Of all 193 relief pitchers with at least 20 innings pitched this season, exactly three have thrown four distinct types of fastballs a minimum of 20 times each: Reed Garrett, Chris Martin, and Cole Sands. They all have one non-fastball offering, but none of them throw it more than a quarter of the time. Justin Choi wrote recently about the strategic options available to pitchers with more than one fastball, but four? Four whole fastballs? These guys feel like doomsday preppers getting ready for some apocalyptic scenario where money is now worthless and fastballs are the new currency.

But anytime a new strategy pops up in baseball, it’s worth checking to see if the outliers are onto something others should attempt, or if their “one weird trick” to pitching works only for them. Shoot, maybe it doesn’t even work for them all that well. Regardless, we’re gonna get to the bottom of what’s going on with these pitchers and all the fastballs they’re hoarding.

Reed Garrett

Garrett has thrown 34.2 innings for the Mets so far this season, posting a 3.12 ERA and a 3.17 FIP. He’s struck out 37% of the batters he’s faced and walked 12%. His performance this year has earned him an ERA- of 81, firmly better than average. What the averages aren’t telling you is that Garrett started the season with a 0.57 ERA in March and April, a ridiculous run that earned him a full breakdown on his evolution from last season by Ben Clemens on April 23. But that April ERA had to buy new pants after swelling to 6.08 in May. His performance has regressed somewhat in June, settling somewhere between those extremes. The current version of Garrett is probably more representative of what the Mets should expect from him moving forward.

The table below shows a breakdown of Garrett’s pitch repertoire with the usage and a few metrics for evaluating each offering (run value per 100 pitches thrown, xwOBA, Stuff+, and Location+). The two most common fastball types (four-seamers, sinkers) that most pitchers feature at the center of their arsenals are the pitches he throws the least. But the metrics linked to Garrett’s outcomes — either actual outcomes (RV100) or expectations based on the characteristics of the outcomes (xwOBA) — agree with his decision to de-emphasizing those pitches. They like Garrett’s four-seamer the least, even though it has his highest velocity and second best Stuff+. The pitch’s Location+ score reveals its critical flaw: a lack of command. Stuff+, RV100, and xwOBA agree that his sweeper and splitter are his two best pitches. Based on usage, Garrett agrees with that assessment.

His pitches mostly hover around league average in terms of individual characteristics, but the sweeper and splitter are both a tick or two harder than average and generate a bit more spin leading to more horizontal break, which is likely why Stuff+ likes them more than the rest of Garrett’s arsenal.

He makes the most of middling pitches by playing them off one another. The sweeper and cutter mirror the spin direction of the sinker and the splitter. As a result the pitches look similar out of the hand but fork in four different directions as they approach the plate to keep the hitter guessing (see movement plot below). So even if hitters guess the horizontal direction correctly, they’ve still got two similarly spinning pitches that fan out vertically as they approach the plate.

Garrett deploys all of his pitches no matter the handedness of the hitter, but he does vary the flavor of his approach. To lefties, Garrett likes to fill the zone with his cutter and dangle the splitter down and away when looking for a chase. To righties, he keeps the hitter off balance by throwing the sweeper to a variety of locations, but then comes down and inside at varying speeds with the splitter and the sinker.

The flowchart below gives us an idea of Garrett’s sequencing habits. He tends to start hitters with a cutter or sweeper. Once ahead in the count, he’s more likely to play around on the periphery of the zone with his sweeper and splitter, whereas while behind in the count he rolls with the four-seamer and cutter as more zone-friendly options. The wOBA values for plate appearances passing through each given count indicate the approach works well in early counts and with two strikes, but not as well when the count forces him back into the zone, in part because his four-seam command limits his ability to actually hit the zone with that pitch when circumstances demand it.

Here’s a representative example of how hitters respond to Garrett’s two-strike splitter.

Looking at swing metrics by pitch type, each pitch adds a valuable tool to his kit. The splitter is Garrett’s best combo play for inducing swings (56% swing rate) without courting disaster. The pitch owns his best swinging-strike rate (30%) and second lowest hard-hit rate (20%) when batters do connect. He gets batters to swing at 74% of the sinkers he throws in the zone, he uses the sweeper to induce weak contact (17% hard-hit rate), and turns to the cutter to mix things up. The four-seamer is the weak link in the chain so long as it keeps taking the scenic route to the catcher’s mitt.

Chris Martin

Martin has thrown 21.1 innings for the Red Sox in 2024, logging a 4.22 ERA with a 3.90 FIP. He’s struck out 28.2% of the batters he’s faced while walking just 2.4% of them. He has been on the IL since June 5 while proactively seeking help with anxiety.

Again, we’ll start with a synopsis of each pitch he throws according to the value metrics. Stuff+, RV100, and xwOBA all like his splitter best. The pitch is very similar to Garrett’s splitter from a velo/movement/spin perspective, but he doesn’t throw it nearly as much. His four-seamer is his next best pitch by RV100 and xwOBA, but fourth best by Stuff+. However, he locates it well enough to still get results. Martin’s cutter is his consensus third-best pitch, striking a balance between stuff and command to get the job done. Like Garrett, Martin’s non-fastball pitch is a sweeper, but unlike Garrett, he throws it so infrequently that it’s hardly worth discussing.

His pitch characteristics all hover around average, thrown maybe a tick or two harder, but with slightly less spin and therefore less movement. What helps overcome somewhat middling profiles is a distinct release point created by his long levers. Though his delivery is composed of a pretty standard three-quarters-ish arm slot, the arm attached to his 6’8” frame allows him to release the ball several inches higher and farther to his right than other pitchers throwing from a similar slot.

Rather than mirroring the spin on his offerings like Garrett, Martin takes a different approach to cultivating deceit. The puzzle for his hitters is more akin to spotting the difference between two nearly identical photos. All of Martin’s pitches spin in a similar direction, and his four-seamer, sinker, and cutter do so at almost the same spin rates. Where they differ is in the amount of active spin, or the amount of spin contributing to the pitch’s movement. The four-seamer, as one might expect, has the most active spin and the most rise. The sinker has a little less active spin and creates more horizontal break and more drop. The cutter drops in a comparable fashion to the sinker, but refuses to follow his fellow fastballs and break toward the third base side. Then there’s the splitter that spins at a much slower rate and with less active spin, which translates to roughly the same amount of horizontal movement as his four-seamer, but with even more drop than the sinker. Yet another carbon copy, but with a small but crucial edit.

Martin uses the same theory to guide his approach to both righties and lefties: Fill the zone with the primary fastball(s), use one of the secondary fastballs as a threat inside, and pepper the bottom of the zone with splitters. Against right-handers the four-seamer and cutter are the pitches he consistently throws to all parts of the zone and the sinker backs the hitter off the inner half of the plate. Against left-handers, Martin stays away from the sinker, so the cutter becomes the weapon he aims inside, while the four-seamer and the splitter maintain their existing roles.

The job of each fastball is further etched in stone by Martin’s sequencing, visualized below. He starts an overwhelming majority of hitters with the four-seamer or cutter and sticks to those zone-friendly pitches if he falls behind in the count. But if he gets ahead, Martin starts mixing in the splitter and sinker. His results tend to be better if he gets to those splitter/sinker counts, but it’s unclear whether that’s because of the effectiveness of those pitches or because he gets too predictable in unfavorable counts.

The swing metrics indicate Martin’s cutter is his best option for getting swings (55% swing rate) that lead to either strikes (13% swinging-strike rate) or weak contact (27% hard-hit rate). The splitter is his overall best bet for a swinging strike (19%), but when hitters do make contact, it yields the highest hard-hit rate (70%). The sinker is most effective when thrown in the zone because it has the lowest out-of-zone swing rate (18%) and in-zone contact rate (78%) compared to Martin’s other offerings. And avoiding contact is key, since the sinker has the second highest hard-hit rate (67%) of the bunch.

Cole Sands

Sands has pitched 32 innings for the Twins this season. Those innings have amounted to a 4.22 ERA and a 3.30 FIP. His strikeout rate sits at 28% and his walk rate is a measly 3%. Sands’ season trajectory mimics Garrett’s: on a rocket to the moon in April, a crash landing in May, and now back up and cruising at altitude in June. At his peak, Sands was striking out Shohei Ohtani on three pitches, and Minnesota was considering stretching him out to start while managing injuries in the rotation; now he’s settled into a multi-inning relief role.

Digging into Sands’ repertoire via the pitch evaluation metrics, his cutter, curveball, and splitter all clock in right around average according to Stuff+, but RV100 favors the four-seamer and hates the curve and split. Comparing the curveball’s xwOBA (.305) to its wOBA (.372) suggests the pitch’s actual outcomes have been a bit unlucky compared to what’s expected based on the batted ball characteristics, which in turn is likely deflating its RV100. Meanwhile the four-seamer and sinker both have better wOBAs when compared to their xwOBAs, suggesting some good luck has swung their way and their RV100s might be a little full of themselves. Luck doesn’t explain the metrics’ diverging opinions on the splitter, suggesting something is amiss with Sands’ execution. Hopefully, this contradiction will untangle itself as we proceed.

In terms of the movement profile broken down in the table below, Sands, like Garrett, mirrors the spin of his breaking ball relative to the four-seamer, sinker, and splitter in an attempt to disguise their true identities until it’s too late for the hitter to react. And concealing those identities is necessary because, as with the other two pitchers, Sands’ pitch characteristics are far more average than overpowering. The furthest he deviates from average is with his extension, but unfortunately he deviates in the wrong direction. His 5.8-foot extension puts Sands roughly six to eight inches below league average. Releasing the ball farther from home plate gives the hitter more of a chance to identify the pitch’s trajectory, which likely explains the lower Stuff+ scores relative to what Garrett and Martin receive for comparable pitches. And while we’re talking pitch trajectory, the extra couple inches of drop on his splitter relative to an average right-handed offering of the pitch might be too much of a good thing; at times it dives too far, too quickly to really tempt hitters.

How the pitches move relative to one another is basically a hybrid of what we’ve seen so far from Garrett and Martin. The fastballs land on the movement plot in roughly the same orientation as the other two, aside from being stretched more vertically. Sands’ curveball operates similarly to Garrett’s sweeper, just with more drop.

Like Martin, Sands doesn’t throw his sinker to lefties, but beyond that omission, Sands attacks hitters in the exact same manner regardless of handedness. He aims to fill up the zone with his four-seamer, works arm side with the cutter and sinker, and keeps the ball down and/or to the glove side with the splitter and curve.

Sands mostly sticks to the standard sequencing playbook, but he’ll reach for any of his non-splitter offerings to begin a plate appearance. If he gets ahead, expect a heavy mix of splitters and curveballs; if he falls behind, expect him to thrown mostly cutters and four-seamers. His adequate command keeps him competitive, since even after falling behind, the average outcomes remain respectable and in line with the more favorable counts.

The swing metrics suggest Sands’ cutter is his best option for inducing weak contact (51% swing rate, 32% hard-hit rate), the four-seamer has the lowest in-zone contact rate (80%) to pair with the second highest in-zone swing rate (71%), and the curveball is best for forcing swings out of the zone (35%) that lead to either a strike (14% swinging-strike rate) or weak contact (25% hard-hit rate).

***

With the four-fastball approach to relief pitching now fully dissected on the lab table before us, I can’t truly say we’ve discovered the next big thing that pitchers everywhere will be rushing to replicate. Though Garrett, Martin, and Sands are the only three relievers doing this out of almost 200, their approach is not as novel as those numbers suggest. What they’re actually doing is leaning on all of the classic pitching fundamentals: changing the hitter’s eye level, attacking the zone to get ahead in the count and then make the hitter chase, varying speeds, varying locations, keeping the hitter off balance. Most relievers execute these fundamentals using one or two overpowering pitches, or in lieu of dominant stuff, they cobble together a few crafty junk pitches. Garrett, Martin, and Sands pitch as if they were junkballers, but instead of throwing knuckleballs or Bugs Bunny changeups, they take their collection of middling fastballs and deploy them as junkballs. They mix and match movement profiles and velocities so hitters can’t sit on certain pitches or locations. They do all the same stuff every pitcher does; they just dress it up a little different. Which in and of itself is novel enough to still be impactful. After all, 10 Things I Hate About You is a singularly great movie, but it’s also a classic Shakespeare play, just dressed up a little differently.

Matt Tuiasosopo has fond memories of his 2013 season with the Detroit Tigers. An October swing of the bat is responsible for one of the few unpleasant memories. Now the third base coach for the Atlanta Braves, Tuiasosopo was watching from the bench when David Ortiz blasted an eighth-inning, game-tying grand slam, a play that saw Torii Hunter tumble into Fenway Park’s home bullpen in a futile attempt to snare the drive. It was the signature moment of an epic ALCS Game 2 that the Red Sox went on to win, and a catalyst to their eventual capturing of the series.

What was it like to be on the wrong side of such a memorable event, and how does he look back at it now that a decade’s worth of water has passed under the bridge? I asked Tuiasosopo those questions when the Braves visited Boston earlier this month.

“That was an intense moment, “ recalled Tuiasosopo, who while not on Detroit’s ALCS active roster was in uniform for the games. “The whole stadium was going nuts. It was really loud. Of course, my first concern was Torii, because he flew over that wall. When he got up, it was ‘Thankfully he’s okay.’ I mean, there were a lot of different emotions.

“It obviously wasn’t fun,” continued Tuiasosopo. “At the same time, as a baseball fan it was, ‘Big Papi against one of our best relievers — Joaquín Benoit was big for us that season — and there was also everything that happened for the city of Boston [the Marathon bombing] that year. The moment was special, even though it sucked on our end.” Read the rest of this entry »

Last Sunday’s column led with Detroit Tigers infielder/outfielder Matt Vierling reflecting on his days as a two-way player in high school and at the University of Notre Dame. This week’s leads with a former two-way player whose career path took a different turn. A native of Saginaw, Michigan who played shortstop and served as a closer at the University of Nebraska, Spencer Schwellenbach is currently a member of the Atlanta Braves starting rotation.

His big-league debut came sooner than expected. The 24-year-old right-hander was drafted in 2021 — Atlanta selected him in the second round — but because of Tommy John surgery he didn’t take the mound until last year. At the time of his May 29 call-up, Schwellenbach had just 110 minor-league innings under his belt. Moreover, he hadn’t thrown a pitch above the Double-A level.

His two-step call-up is something he’ll never forget.

“They actually told me I was going to Triple-A,” said Schwellenbach. “I showed up in Gwinnett, threw a bullpen, and after I got done they asked if I was all packed up to go to Virginia. I said, ‘Yeah, I’ve got all my stuff here.’ They were like, ‘Well, unpack your stuff, you’re throwing in Atlanta on Wednesday.’ I was so taken off guard that I didn’t know what to say. It was like, ‘holy crap.’ I called my parents, my fiancee, my brothers, my sister. It was awesome.” Read the rest of this entry »

The Portland Sea Dogs roster includes three Top 100 prospects, but neither Roman Anthony (15), Marcelo Mayer (42), nor Kyle Teel (83) has been the Double-A affiliate’s best player so far this season. That distinction belongs to a 23-year-old, shortstop-turned-left-fielder whom the Boston Red Sox drafted 69th overall in 2019 out of the Carlos Beltran Baseball Academy. Along with playing stellar defense at a new position, Matthew Lugo is slashing .306/.404/.653 with 10 home runs and an Eastern League-best 191 wRC+.

Markedly-improved plate discipline has played a big role in his breakout. Last year, Lugo logged a 5.9% walk rate and a 27.6% strikeout rate. This year those numbers are 13.4% and 22.5%.

The key to his newfound ability to dominate the strike zone?

“Timing,” explained Lugo, who takes his cuts from the right side. “Last year, I had a lot of movement with my hands, which made me inconsistent being on time with the pitcher. My hands were very low, and then when I got to the launch position they were very high; there was a lot of distance for my hands to go through. This year, I’m closer to my launch position before I swing. I also had a [bat] wiggle and this year I just get to my spot with no wiggle. I’m getting into my spot early and have more time to see the pitch, so I’m making better swing decisions.”

The decision to move Lugo off of his natural position and into an outfield corner wasn’t based on defensive shortcomings, but rather on the arrival of Mayer. The high-ceiling shortstop was promoted to Portland last year on Memorial Day weekend, and given his first-round pedigree, he wasn’t going to be the one moving. Read the rest of this entry »

This is the year of the splitter. In 2024, 3.1% of all big league pitches thrown have been splitters compared to 2.2% in 2023, a year-over-year increase of 41%. Aficionados of the split-fingered fastball include former NPB stars like Yoshinobu Yamamoto and Shota Imanaga, longtime MLB users like Joe Ryan and Fernando Cruz, and an assorted collection of hurlers who’ve added a new splitter or featured one much more prominently in their arsenal this year. And few starters have scaled up their splitter usage more than the man atop the pitcher WAR leaderboard: Tanner Houck.

Houck has thrown a splitter his entire time in the majors, but he’s taken it to a new level this year by doubling its usage. Among qualified starters, Houck throws the sixth-highest percentage of splitters, while his splitter’s 110 Pitching+ ranks fifth, ahead of Ryan and Imanaga. The rise of Houck’s splitter, combined with the arsenal tweaks he’s made to throw it more, have transformed him from a mixed-role swingman to slam-dunk frontline starter.

Houck has spent most of his big league career straddling the line between starter and reliever. He pitched mainly as a starter during his 2021 rookie season, but never completed the sixth inning in any of his starts. His sophomore campaign saw him make multi-inning appearances out of the bullpen. Back in the rotation last year, he posted an ERA above five and struggled to get outs as his pitches lost their bite later in starts.

Aside from stamina, Houck’s delivery served as a hurdle to his abilities as a starter. While a handful of starters fire from low arm slots, Houck is one of the only true sidearmers currently in a big league rotation. He doesn’t have an outlier release point thanks to his tall stature and mechanics that carry him toward the first base side, but his arm angle is certainly the lowest among starters. Houck’s delivery provides a great viewing angle for left-handed hitters, who comprise the majority of his competition as opponents stack platoon bats against him.

In 2023, lefties slashed .271/.356/.502 against Houck, roughly the equivalent of having to face Rafael Devers for the entire season. But through his first 10 starts of this year, he’s held them to a line so poor I can’t find a qualified hitter whose numbers I can compare with it. Neutralizing the platoon advantage is a huge deal for a pitcher with his arm angle, and much of this impressive feat has to do with his splitter.

Let’s take a look at what Houck’s approach to pitching looked like before ramping up the use of his splitter. Like most low-slot pitchers, his two primary offerings are a sinker and slider, taking advantage of the east-west movement his arm action produces. Both these pitches are chart-topping in terms of movement, dropping more than average due to their lack of backspin, and his slider breaks to the left even more than most sweepers (though Statcast doesn’t classify it as one).

While these two pitches made right-handed hitters absolutely futile against Houck, sinkers and sweeping sliders tend to generate large platoon splits, compounding with the advantage lefties gain from seeing the ball clearly out of his hand. Houck’s slider drops so much that lefties can’t do much with it, but his sinker moves directly into the path of their barrels, eager to get hammered. In the past, Houck primarily used four-seamers and cutters as his hard offerings against lefty opponents, hoping the rising action would be enough to miss bats. But these pitches still had too much arm-side movement and didn’t generate upward Magnus force, instead staying on plane with lefty swings.

Houck’s approach to lefties wasn’t working, and he needed a change. In came the splitter. What was once a distant fourth offering became his offspeed weapon. He tinkered with its shape, adding nearly four inches of drop to make it more distinct from his sinker. He tightened up its command, finishing down in the zone more consistently and spiking fewer in the dirt. The end result of these adjustments is a lethal pitch that has been a key contributor to Houck’s success.

Houck’s splitter leads his arsenal in both swinging strike rate and putaway rate, indicating it’s already his go-to weapon in two-strike counts. And while it’s been successful at missing bats, the results it generates when batters put it in play may be even more impressive. His split has the lowest launch angle allowed of any individual pitch from a starter; it’s one of just a dozen with a negative average launch angle. After years of allowing lefties to crush the ball in the air, he’s inducing a higher groundball rate against lefties than righties in 2024. These underlying changes have manifested in big time results – lefties have just a .038 ISO against Houck this season and have yet to homer, and Statcast metrics like barrel rate confirm this is no fluke.

The emergence of Houck’s splitter has also cut down his walk rate significantly, as he’s jumped from the 42nd to the 88th percentile in avoiding free passes. Previously, Houck often nibbled around the zone against lefties, afraid of what they could do to his fastball and cutter. Now armed with a pitch that limits damage, he’s fearlessly attacking the strike zone, improving his splitter zone rate by 14 percentage points and his overall zone rate by nearly five.

The effectiveness of his splitter has also made Houck’s sinker a more effective strike stealer because hitters watch it go by expecting it to drop beneath the zone. Houck currently ranks second to Seth Lugo in called strike rate, getting ahead of hitters before disposing of them with the slider and splitter. His improved control of the count is a big reason why he ranks fourth in K-BB% increase relative to 2023.

What impresses me most about Houck’s splitter is the sheer frequency with which he deploys it against lefties, especially at the expense of his fastballs. He’s throwing significantly fewer cutters and has shelved the four-seamer entirely. After unsuccessfully throwing the kitchen sink against opposite-handed opponents, he’s essentially become a two-pitch pitcher against lefties, throwing either a slider or splitter nearly three-quarters of the time.

It’s not often that you see a pitcher use two different non-fastballs as their primary offerings, but this strategy has paid off – not just for Houck but also for the Red Sox as a whole. Last month, Chris Gilligan wrote about Boston’s staff leading the leaguewide shift away from the fastball, pointing out Houck’s four-seamer had a horizontal movement profile ripe for hitters to feast on. Just a couple decades ago, a starting pitcher who almost exclusively relied on sliders and splitters against left-handed hitters would have been unthinkable, but the secondaries-first approach is now a strategy that entire teams are embracing with tremendous results.

Houck’s run as the top-performing pitcher in the majors probably won’t last — he has an unsustainably low 2.6% HR/FB rate — but the excellence of his splitter has certainly put a massive up arrow on his future projection. Just a couple years ago, it would’ve been difficult to envision that the sidewinding swingman who couldn’t handle lefties would become an excellent starter who consistently works into the seventh inning. But with a surprisingly simple fix, Houck has made it happen.

Welcome back to Top of the Order, where every Tuesday and Friday I’ll be starting your baseball day with some news, notes, and thoughts about the game we love.

Losing your starting shortstop and no. 2 hitter all at once is one of the worst things that can happen to a team, but somehow, the Phillies have weathered the absence of Trea Turner better than anyone could have hoped. The All-Star departed Philadelphia’s May 3 game against the Giants (in which he also scored from second on a wild pitch!) with a strained hamstring; at the time, he was expected to miss about six weeks, though he is “progressing at a surprising pace given the original timetable,” as Matt Gelb of The Athletic recently reported.

Obviously, the Phillies would love to have Turner back ahead of schedule, but they have more than held their own without him. They are 12-3 in their 15 games since May 4, their first following Turner’s injury, and their 123 wRC+ is the second-best mark in the majors during that stretch, behind only the Yankees. Philadelphia’s success isn’t due to the other positions carrying the load; though they’ve certainly been playing well, too. Rather, Philadelphia’s shortstop platoon of Bryson Stott and Edmundo Sosa has combined for a 163 wRC+ over that 15-game span; that’s better than every other NL team’s shortstop production. Only the Orioles, led by Gunnar Henderson, have gotten more offense at short.

Since Turner went down, Stott leads the Phillies with a 230 wRC+ and ranks fourth in the majors among players with at least 50 plate appearances in that span. Meanwhile, Sosa’s 167 wRC+ as a shortstop is the second-best mark since May 4, behind Henderson (187). Catcher J.T. Realmuto (153), first baseman Bryce Harper (180), and DH Kyle Schwarber (129) have also propelled the offense over these last 15 games. Additionally, the Phillies have received surprising contributions from utilityman Kody Clemens, who’s popped a couple of homers and has a 183 wRC+ across his 25 plate appearances since he was recalled to replace Turner on the roster. Even right fielder Nick Castellanos has woken up a bit, mustering a respectable 117 wRC+ during the 15 games without Turner after having posted a woeful 42 wRC+ from Opening Day through May 3.

On the other side of the ball, Phillies pitchers have kept up their end of the bargain for pretty much the whole season, and they’ve continued to perform well over the last 15 games, ranking fifth in ERA (2.78) and third in FIP (3.22).

All in all, even without Turner, everything’s clicking for the Phillies this season. They enter play Tuesday with a five-game lead over the Braves in the NL East, with the highest scoring offense (5.33 runs per game) and by far the most valuable pitching staff (9.3 WAR) in the majors. As Jake Mailhot noted in yesterday’s Power Rankings, Philadelphia has played the weakest schedule in baseball so far this season, so perhaps the team won’t maintain its .708 winning percentage the rest of the way. Even so, the Phillies have been winning at an .800 clip without their superstar shortstop. That is certainly encouraging.

Quick Hits

Let’s run through some other notable things from the past few days of games:

• The Yankees’ seven-game winning streak was snapped Monday night in heartbreaking fashion, when closer Clay Holmes allowed his first four earned runs of the season to blow a 4-1 ninth-inning lead against the Mariners in an eventual 5-4 Seattle win. Nevertheless, New York is playing its best baseball of the year right now. Aaron Judge has continued his reign of terror on opposing pitchers, going his 14-for-28 with 10 extra-base hits, including four homers, in his last eight games, and after a mini-slump, Juan Soto is catching fire again; over his last four games, he is 7-for-15 (.467) with two homers. Luis Gil, who wouldn’t have made the rotation if not for Gerrit Cole’s injury, struck out 14 in his start on Saturday. The Orioles lost on Monday as well, keeping the Yankees’ division lead at two games. The two sides don’t meet again until June 18.

• Like the Yankees, the Astros also coughed up an early lead on Monday night after a recent stretch of excellence. Houston led 6-1 before the Angels scored seven runs in the top of the fifth inning in what ended up as a 9-7 Astros loss. Still, the Astros have won each of their previous three series and jumped back into the AL West race after their dreadful start. They enter play Tuesday 4.5 games behind the first-place Mariners. Less than two weeks ago, on May 8, they were 8.5 games back. Yordan Alvarez still isn’t hitting anywhere near his abilities — though perhaps a double, single, and walk on Monday portends the start of a hot streak — but Alex Bregman has woken up and Kyle Tucker is playing like an MVP.

• Red Sox third baseman Rafael Devers set a franchise record Monday night when he homered in his sixth consecutive game. His home run, a two-run blast, came in the fourth inning off Rays righty Taj Bradley and extended Boston’s lead in its 5-0 win. Over his last six games, Devers is 7-for-24, his only non-homer hit being a single, with a 1.042 slugging percentage. With his home run Monday night, Devers surpassed the six other players who went yard in five straight games with the Red Sox: Bobby Dalbec (2020), Jose Canseco (1995), George Scott (1977), Dick Stuart (1963), Ted Williams (1957), and Jimmie Foxx (1940). The major league record for consecutive games with a home run is eight, shared by Dale Long (1956), Don Mattingly (1987), and Ken Griffey Jr. (1993).

Kyle Harrison was pitching for the Double-A Richmond Flying Squirrels when he was first featured here at FanGraphs in August 2022. Then a fast-rising prospect in the San Francisco Giants system, the now-22-year-old southpaw had broken down the early evolution of his arsenal for me prior to a game at Portland, Maine’s Hadlock Field. Fast forward to this past week, and we were reacquainting at a far-more-fabled venue. Harrison was preparing to take the mound at Fenway Park for his 14th big-league start, his seventh this season.

As I’m wont to do in such scenarios, I asked the dark-horse rookie-of-the-year candidate what’s changed since our 20-months-ago conversation. Not surprisingly, he’s continued to evolve.

“I’ve added a cutter, although I haven’t thrown it as much as I’d like to,” Harrison told me. “Other than that, it’s the same pitches. The slider has been feeling great, and the changeup is something that’s really come along for me; it’s a pitch I’ve been relying on a lot. I really hadn’t thrown it that much in the minors — it felt like I didn’t really have the control for it — but then all of a sudden it clicked. Now I’ve got three weapons, plus the cutter.”

Including his Thursday effort in Boston, Harrison has thrown his new cutter — Baseball Savant categorizes it as a slider — just six times all season. Which brings us to his other breaking ball. When we’d talked in Portland, the lefty called the pitch a sweepy slider. Savant categorizes it as a slurve.

Wilyer Abreu has been one of the top rookies in baseball this season. Along with playing above-average defense in right field, the 24-year-old Boston Red Sox outfielder has logged a 155 wRC+ while slashing .316/.396/.519 over 91 plate appearances. His 1.1 WAR ranks second among rookie position players, behind Baltimore’s Colton Cowser. Granted, less than a month’s worth of games is hardly enough time to know if he’ll keep this up, but Abreu’s strong start is encouraging nonetheless.

He similarly impressed last year in a 28-game cameo. Debuting in late August, Abreu went 24-for-76 (.316) with two home runs, the exact same numbers he had this April. There’s juice in his bat. Eric Longenhagen wrote last summer that Abreu “has above-average raw power,” and the youngster’s production has backed up that prose. By the time of his call-up, Abreu had gone yard 22 times, with a 135 wRC+, at Triple-A Worcester.

His path to the big leagues included more than your typical climb up the minor league ladder. The Red Sox acquired Abreu from the Houston Astros, along with Enmanuel Valdez, in the trade for Christian Vázquez on August 1, 2022 — but that’s also only part of the story. The Maracaibo, Venezuela native had intended to sign with Boston in 2016, but the Red Sox were locked out of the international amateur market in 2016-17 as punishment for violating international-signing regulations. Abreu subsequently signed with the Astros in 2017; he waited an extra year to sign because he was told he’d get a better offer if he did.

He’s evolved as a hitter since inking his first professional contract. Read the rest of this entry »

Justin Slaten is well on his way to becoming a Rule 5 success story. Selected by the Mets out of the Rangers organization this past December and subsequently swapped to the Red Sox on the same day, the 26-year-old right-hander has come out of the Boston bullpen eight times and relinquished a single run in 14 1/3 innings. Moreover, he’s been stingy with baserunners, allowing just six hits and a pair of free passes. Four weeks into the season, he’s been the team’s top reliever.

His lone low moment to date came in his major league debut. Pitching in Seattle in the third game of the season, Slaten surrendered a 10th-inning walk-off single to Julio Rodríguez on his fifth big league pitch. Since that time, he’s been borderline flawless — opposing hitters have gone a paltry 5-for-45 against his power arsenal, with a Mike Trout triple accounting for the only extra-base knock. He’s punched out 11 batters.

Slaten’s mix — 38.5% cutters, 35.2% sweepers, 24.0% four-seamers, 2.2% curveballs — has been more varied than he expected it to be when he broke camp. Other than that, he’s mostly the same hurler who attracted Rule 5 interest by overpowering hitters while pitching with the Rangers’ Double-A and Triple-A affiliates last year.

“My only approach coming in was to throw everything in the zone, trying to get the best results,” Slaten told me before a recent game. “The only thing that has changed a little bit is the pitches that have been called. I’m probably throwing a higher percentage of breaking balls than I have in my entire life. But nothing has changed about the way I throw them, or try to execute.” Read the rest of this entry »

Welcome back to Top of the Order, where every Monday, Wednesday, and Friday, I’ll be starting your baseball day with some news, notes, and thoughts about the game we love.

Blake Snell’s Giants tenure couldn’t be going much worse. In three starts spanning just 11.2 innings, he’s allowed 15 runs — nearly a third of last year’s total in only 6.5% of the innings — with a hard-hit rate that’s up nearly six percentage points from last year. Some of his woes can be attributed to small samples and bad luck — his 11.57 ERA is much higher than his 4.05 xERA — but this clearly isn’t how he and San Francisco drew it up. And that was before news broke Wednesday that the Giants were placing Snell on the 15-day injured list with an adductor muscle strain in his groin area. He has dealt with this injury twice before in his career, though he doesn’t seem worried that it’ll a long-term issue:

Snell had the same injury in 21 and 22, says he caught it early and is hopeful he misses minimal time. Maybe just slightly more than the 15 day minimum.

After his disappointing free agency, Snell could at least look forward to the possibility that he’d earn $32 million this year and pitch well enough to opt out and seek a more lucrative deal after the season. But now that he is going to miss at least three starts, following his three clunkers, it appears unlikely that he’ll be in a position to risk the $30 million he’s set to make next year if he stays.

The more immediate concern for the Giants, though, is how they’ll fill Snell’s spot in the rotation. Logan Webb is on a roll (29 innings in his last four starts, with just three runs allowed), and Jordan Hicks is pitching quite nicely, with a 1.61 ERA in five starts. Keaton Winn (3.54 ERA) is also chipping in on the back end, and while top prospect Kyle Harrison has struggled to a 5.00 ERA so far, there’s certainly room for him to get better. The fifth spot, however, looks like something of a mess.

The Giants had hoped Alex Cobb would be in the rotation by now after he recovered from hip surgery more quickly than expected, but he strained his elbow as he ramped up and was transferred to the 60-day IL instead. That leaves the Giants with two options: go with bullpen games, as they did in a pinch on Wednesday when Snell was scratched, or bring up someone from Triple-A. The latter feels far more likely, especially with Mason Black (1.53 ERA in four starts) pitching very well with Sacramento. Black hasn’t thrown more than five innings or 70 pitches in a start this year, so he won’t exactly take the load off San Francisco relievers, who have the second-highest bullpen ERA in the majors. Still, promoting Black appears to be the best way through this unfortunate situation.

…

On the opposite coast, the Red Sox placed Opening Day starter Brayan Bello on the IL with lat tightness, joining fellow starters Lucas Giolito, Nick Pivetta, and Garrett Whitlock. As with Snell’s injury, Bello seems to have avoided serious injury, but in the best division in baseball, Boston can hardly afford to miss its no. 1 starter for even the minimum 15 days.

Rather amazingly, despite all those injuries, the Red Sox have the lowest ERA and FIP in the majors, with Kutter Crawford leading the way with a 0.66 ERA (two earned runs in 27.1 innings) that’s backed up by an also excellent 2.28 FIP. Tanner Houck (1.65 ERA/2.24 FIP) has become indispensable as well.

But things get dicey after that. The rest of the rotation now consists of Cooper Criswell, Josh Winckowski, and Chase Anderson, and because the latter two opened the season as relievers and aren’t stretched out to start just yet, their outings have turned into bullpen games.

This creates an awfully precarious position for the Red Sox bullpen, which has performed well thus far but doesn’t have the depth to cover an extended workload. Boston has already tapped into its pitching pipeline by calling up Criswell, and none of its other Triple-A pitchers are performing well enough to warrant a promotion to the majors. Moving Winckowski and Anderson to the rotation, then, has the compounding effect of weakening the bullpen, especially since Winckowski had pitched in high leverage situations.

Checking in on Wyatt Langford

Things certainly haven’t been rosy for Rangers rookie Wyatt Langford, who is batting .253/.337/.308 (89 wRC+) with no home runs across 104 plate appearances.

The 22-year-old has excellent raw power but just hasn’t tapped into it in the majors yet. His average exit velocity and hard-hit rate are both well below league average, with his barrel and sweet spot rates just barely above it.

It’s not all bad for Langford; he has elite speed that’s allowed him to beat out some infield hits, and his swing decisions are generally good, with chase and contact rates both well better than major league averages. But having great plate discipline can sometimes handcuff batters when they’re scuffling, and that seems to be the case with Langford. He’s talking too many pitches over the heart of the plate.

Pitch selectivity is a skill that depends just as much on swinging at the right pitches as it does laying off the wrong ones. A hitter may not get his ideal pitch during an entire game, let alone a single plate appearance, and taking too many hittable pitches leads to a lot of pitcher’s counts. It appears Langford would be much better off swinging more and using his quick hands and raw talent to make the most out of the pitches he gets over the plate rather than waiting around for the best possible one.
