Willie Mays was already a superstar by the time the Giants moved across the country following the 1957 season, yet the denizens of San Francisco did not exactly embrace him. They took much more quickly to Orlando Cepeda, who homered against the Dodgers in his major league debut on April 15, 1958, the team’s first game at Seals Stadium, its temporary new home. The slugging 20-year-old first baseman, nicknamed “The Baby Bull” — in deference to his father Pedro “The Bull” Cepeda, a star player in his own right in their native Puerto Rico — was a perfect fit for San Francisco and its culture. He helped to infuse excitement into what had been a sixth-place team the year before, winning NL Rookie of the Year honors in 1958 and kicking off a 17-year career that included an MVP award, a World Series championship, and an induction into the National Baseball Hall of Fame, not to mention a statue outside Oracle Park.

Sadly, 10 days after Mays’ death at the age of 93, the 86-year-old Cepeda passed away as well. The Giants and the Cepeda family announced his death on Friday night — fittingly, during a game against the Dodgers; fans at Oracle Park stood to observe a moment of silence. “Our beloved Orlando passed away peacefully at home this evening, listening to his favorite music and surrounded by his loved ones,” said Nydia Fernandez, his second of three wives, in the statement. No cause of death was provided.

As the second Black Puerto Rican to play in the AL or NL, after Roberto Clemente, Cepeda became a hero in his homeland as well as a favorite of Giants fans. He spent nine seasons with the Giants (1958-66) before trades to the Cardinals (1966–68) and Braves (1969–72), followed by brief stints with the A’s (1972), Red Sox (1973), and Royals (1974) at the tail end of his career. The 6-foot-2, 210-pound righty was a middle-of-the-lineup force on three pennant winners, including the 1967 champion Cardinals, and was selected for an All-Star team 11 times, including two per year from 1959–62; he was the first Puerto Rican player to start an All-Star Game in the first of those seasons. He was the first player to win both the Rookie of the Year and MVP awards unanimously; Albert Pujols is the only one to replicate that feat. Cepeda finished his career with 2,351 hits, 379 homers, 142 steals, and a lifetime batting line of .297/.350/.499 (133 OPS+).

Not everything came easily for Cepeda. If not for the pitcher-friendliness of the Giants’ home ballparks — first Seals Stadium and then Candlestick Park — as well as a series of knee injuries that led to 10 surgeries, he might have hit at least 500 home runs. His path to the Hall of Fame took an extreme detour due to a conviction for smuggling marijuana, which resulted in a 10-month stint in federal prison as well as a humiliating fall from grace in Puerto Rico. Only after his release and his conversion to Buddhism was he able to rehabilitate his image and work his way back into the game’s good graces, a process that culminated with his election to the Hall of Fame by the Veterans Committee in 1999, 25 years after his final game. He was the second Puerto Rican player inducted, preceded only by Clemente. Read the rest of this entry »

Blake Treinen has spent an entire career as one of the best sinker-heavy relievers in all of baseball. Since his debut, he’s been one of the best relievers in baseball — period. That sounds like hyperbole but it isn’t. From 2014 through 2022, he ranked ninth in FIP-based WAR and fourth in RA9-WAR among all relief pitchers. He also ranked second in groundball rate among relievers who threw 400 or more innings. That’s elite performance, and he did it with a consistent attack of sinkers and sliders.

As his career has worn on, Treinen has made one big shift: He started throwing a huge sweeping slider. He was an early poster boy for the sweeper revolution. From 2014 through 2020, his slider averaged about an inch of horizontal movement. Starting in 2021, he changed the way he threw it, and that number blew up to nearly seven inches. That turbo-charged his strikeout rate, and 2021 was one of his better seasons despite intermittent command problems.

Those two things encompass most of what people know about Treinen. He gets a ton of grounders and he throws a big old sweeper. In fact, he was at the vanguard of a pitcher type that now seems to populate every major league bullpen: the sinker/sweeper righty. You can picture this guy, even if you don’t know his name on every single squad. He lives on the east/west plane, and produces plenty of ugly swings and probably a hit batter or two when his sinker veers into the righty batter’s box seemingly out of nowhere.

Tim Herrin is quietly having one of this year’s best seasons among pitchers who are unlikely to be named to the American League All-Star team later this month. The 27-year-old left-hander has come out of the Cleveland Guardians bullpen 38 times and boasts a 1.07 ERA and 2.48 FIP over 33 2/3 innings. Moreover, he’s punched out 34 batters, and none of the 18 hits he’s surrendered have left the yard.

Uncle Charlie has been his primary weapon. Herrin has thrown his curveball 40.6% of the time this season, the second-highest percentage — behind only Kansas City’s Nick Anderson at 45.1% — among pitchers who have worked at least 30 innings. The usage represents a marked change from a year ago. In his 2023 rookie season, Herrin threw his curveball just 12.2% of the time while logging a 5.53 ERA and 3.87 FIP.

Herrin discussed his hook prior to a recent game at Cleveland’s Progressive Field.

———

David Laurila: Is the curveball your best pitch? You’ve certainly been throwing a lot of them.

Tim Herrin: “Yeah, I mean, the usage is up a lot compared to previous years. It’s a pitch I worked on throughout the offseason, trying to be able to command it a little bit better. It used to be more of a two-strike strikeout pitch, and now I can use it to get ahead in counts as well as to put guys away. It’s been a good pitch for me.” Read the rest of this entry »

Royce Lewis is one of the most intriguing hitters in the game right now. Despite how fantastic he has been on a rate basis, it’s hard to fully evaluate his overall value as a hitter because of how little he has played. He has amassed 4.1 WAR and a 159 wRC+ across 93 career games, but as is well known, he’s been limited due to a series of injuries that includes two ACL tears, quadricep and hamstring issues, and an oblique strain.

This season, his explosive performance has added some confidence in what he can be as a hitter. Despite suffering a quad injury on Opening Day that kept him out of the lineup for two months, he’s clobbered 10 home runs in 23 games, showing that he doesn’t need a bunch of plate appearances to shake the rust off his swing before catching fire. His raw talent has never been in question, but there’s one part of his game throughout his power surge that seems to defy logic and is worth keeping an eye on moving forward: His xwOBACON sat at .473 entering play Sunday. If he were a qualified hitter, that would rank in the top decile. Given what we’ve seen from Lewis, that isn’t all too shocking – he can really put a charge into the ball. But when zooming in a bit on a particular detail of his swing, it becomes a bit surprising. Here are the leaders in xwOBACON to date in 2024:

I’ve included Vertical Bat Angle (VBA) here because, except for Juan Soto, Lewis has the lowest average VBA of all hitters on this list. After Lewis, the hitter with the next-lowest VBA is Giancarlo Stanton, who generates so much power and bat speed that it would be nearly impossible for him not to have a top-of-the-line xwOBACON, even with such an unorthodox swing. How Soto can impact the baseball with ferocity despite having one of the flattest swings in the entire game is a bit more complex. The simplest explanation is he has incredible upper body athleticism, which allows him to let the ball get extremely deep in the hitting zone and still adjust his bat path to get on plane with the pitch.

Otherwise, though, hitters hardly ever generate this level of contact quality with these types of VBAs. So it’s remarkable that Lewis is among the exceptions. For the rest of this piece, let’s ignore Stanton because he is, in the words of Yankees manager Aaron Boone, a “weirdo” and what he does with his violent, choppy swing is almost certainly impossible to replicate. Soto is also a singular hitter; the difference is that what he does — using his flatter bat path to make more consistent contact while still having the strength to do damage, and pairing that hit tool with 80-grade swing decisions — would be worth emulating if anyone were talented enough to do it. At a glance, it seems Lewis might have the skills to follow a somewhat similar recipe. So far this season, Lewis has a 98th percentile SEAGER, a metric from Robert Orr that weighs how selective hitter are and the rate at which they attack hittable pitches. It’s especially encouraging that Lewis lets only 28.2% of hittable pitches pass him by, meaning that when he gets a pitch he can crush, he’s attacks it. That’s a great foundation to have.

To better understand his swing, I’ll refer you all to the third hitting installment from Tess Taruskin’s invaluable video scouting series, specifically the part where she compares grooved and adjustable swings. Because Lewis is a hitter with such a flat swing, my initial hunch was that most of his damage comes against pitches down the middle or in top half of the zone, leaving a hole for pitchers to target at the bottom of the zone. This would indicate that Lewis would have a grooved swing, one that repeats a specific swing path over and over, leading to a limited space for barrels. Although Lewis’ sample size is still hardly significant this year, it’s worth looking at where his best swings in terms of contact quality have been located. Here are his 10 home runs this season:

Interesting. All of Lewis’ homers have come from the middle of the zone. That’s not necessarily a bad thing – the best hitters in baseball are the ones who crush mistakes the most often. And as we saw from his SEAGER, he is great at attacking pitches in hittable zones. Basically, we can’t just knock him simply because his homers come from meatballs. However, it’s relevant context to the conversation around distinguishing whether his swing is grooved or adjustable. To go a bit further than just his pitch chart on home runs, we can look at his performance by zone to see if he’s had a hole below the zone.

Lewis has actually been quite successful in the bottom of third of the zone, with a .380 wOBA and .355 xwOBA on pitches in this location. (I included both 2023 and 2024 to increase the sample size a bit.) That’s pretty impressive for a hitter with such a flat swing. Soto’s wOBA/xwOBA line in that span is .264/.260, though his sample is much larger. Lewis’ contact quality on lower-third pitches is also quite strong.

Looking at video, it becomes clear how Lewis is succeeding against lower-third pitches, and this is where he is different from Soto. Remember, it is Soto’s upper body flexibility that propels him to impact pitches that get deep in the zone against him. Lewis, on the other hand, uses his lower body to get down in the zone and do damage on pitches in the bottom third:

If you focus on where Lewis’ head starts on these swings versus where it finishes, you can see the angles he can create with his lower body to get his barrel to the lower third despite his flat swing. It’s reminiscent of Fernando Tatis Jr. The hands start high and stay high, but the lower body creates space for the barrel to still maintain a positive attack angle – the angle of the bat path at contact relative to the ground – at the bottom of the zone. It’s a difficult move to make, but when your swing is this adjustable, you can rely on it from time to time when you identify pitches correctly.

The contrast between Lewis and Soto is a great reminder of how different hitters can be, even when a key trait in their swings is similar. Lewis’ superpower lies in his lower body. Whether the pitch is inside, outside, or in the middle of the zone, he uses his legs and hips to go down and get pitches.

Now, if I were an opposing pitcher, I’d challenge Lewis to make these moves over and over again and prove he can still elevate pitches down in the zone. Like I’ve said, we’re dealing with a limited sample. However, based on what we’ve seen so far, there is reason to believe Lewis has the skills needed to continue producing elite contact with his flat swing.

Below is an analysis of the prospects in the farm system of the Boston Red Sox. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the fourth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

The Angels are in a rough place. With Mike Trout injured, Shohei Ohtani departed, and pitchers like Patrick Sandoval and Reid Detmers injured or struggling, it’s no surprise that they’re on pace for another 90-loss season despite a recent six-game winning streak. Their main source of their woes has been their long-struggling pitching staff, which this year has the third-worst ERA and walk rate in the majors. And while the Angels have taken extreme measures to add pitching depth to their farm system, the next generation of young pitchers in Anaheim aren’t exactly aces. This is to say that any short-term improvements to the staff will have to come from improvements to hurlers already on the big league roster. This year, they’re attempting to do just that by embracing the newest pitch to come into vogue: the splinker.

The splinker is still pretty new in the timeline of pitch design; its early adopters include Jhoan Duran and Paul Skenes. This sinker-splitter hybrid is difficult to classify because so few pitchers throw it, but such offerings generally sit in the same velocity band as four-seam fastballs while killing spin and lift in a manner similar to splitters and changeups. The end result can be downright nasty: Skenes has accumulated a +10 run value with his splinker across just nine starts, only a couple runs better than the first Angel to pick up the pitch, José Soriano.

For the past two-plus years, the Phillies have been one of the most successful teams in baseball. They’ve been to the World Series once and nearly made it back again last year. They’re sixth in the league in wins over that span and are within hailing distance of everyone other than the Dodgers and Braves. They have the best record in baseball this year, and it’s hardly smoke and mirrors; they’re playing .655 baseball with the run differential of a .654 team.

How do they do it? Their approach is strikingly simple. First, get a group of good pitchers. Zack Wheeler and Aaron Nola form one of the best duos in the majors. Ranger Suárez is underrated, though less so after a banner first half. Cristopher Sánchez has been a revelation. The bullpen has been elite for this entire run. Simply put, the team doesn’t allow many runs.

The second part of Philadelphia’s winning formula is to have some burly power hitters smash dingers. Kyle Schwarber has hit 110 homers since the start of 2022, second only to Aaron Judge. Bryce Harper has missed time with injury, but he’s been one of the best in the game when healthy. The rest of Philadelphia’s attack is a bunch of complementary pieces (maybe that sells Trea Turner short, but I’m working an angle here) meant to help the boppers out.

Over the next few weeks, that proven formula is going to be severely tested. Last Thursday night, both Harper and Schwarber sustained fluke injuries. First, Schwarber planted awkwardly on a throw from the outfield and strained his groin. Calling it a fluke might not go far enough – this was only his third time in the field this year, as he usually handles DH duties. It wasn’t a contact injury, just an awkward step on a routine play.

Schwarber departed the game in the eighth inning. In the ninth, Harper grounded out to end the game. He felt his hamstring tighten up as he ran to first base. He was diagnosed with a strained hamstring, and both he and Schwarber hit the IL before the next day’s games.

First, the bad news. The Phillies are going to have to make the approach they’ve used to such good effect work without one of its key components. Harper and Schwarber have both been instrumental to Philadelphia’s recent run of success. This year, they’ve been the team’s best two hitters, give or take Turner’s abbreviated season. They’ve contributed 37 homers and an aggregate 150 wRC+. They’ve been worth 5.7 WAR, and that despite the positional adjustments that likely understate the value of first basemen and DHs.

Here’s an easy way to think about how the Phillies will look without their stars: So far this year, they’ve won 55 games and lost 29, a .655 winning percentage. Now, let’s subtract the 5.7 wins between Harper and Schwarber and replacement level, and add those games to the loss column instead. Now they’d be a .587 baseball team. That’s a .068 drop in winning percentage, a significant gap.

That sounds pretty dire, particularly given that Harper and Schwarber don’t occupy roles that are easily replaced. The only other obvious DH on the roster is Nick Castellanos, and he’s no Schwarber. There’s no obvious first base replacement, either – Kody Clemens has played in each of the three games since Harper’s injury, but that’s more by necessity than design. His natural position is second base, and he’s played a utility role in recent years.

While the Phillies pitching staff is almost comically deep, the same can’t be said about their position players. Johan Rojas is back in the lineup as a frequent starter with Castellanos now out of the field, but he had been demoted to Triple-A on the back of a dreadful offensive start. Clemens has been injured himself. David Dahl is getting big at-bats for the team. Whit Merrifield is hitting .193/.273/.289 and will be playing much more to make the various positional permutations work. The Phillies have a 101 wRC+ if you exclude their two injured stars. This went from a fearsome lineup to a middling one overnight.

There’s good news for Philly fans, though. First, neither injury appears to be serious. The Athletic’s Matt Gelb reported that both players could at least theoretically miss the minimum 10 days with their injuries. Manager Rob Thomson said that he thought both players could be back before the All-Star break. Sure, having an average offense instead of a great one is a big problem should their injuries linger and cause them to miss the rest of the season, but if both Harper and Schwarber return on July 8, the team is only looking at six more games without their services. They’ve already gone 2-1 in their three games since the injuries.

Remember that 68-point drop in winning percentage? That comes out to a difference of 0.4 wins over a six-game stretch. Playing without your offensive core is a blow, but baseball is a game driven heavily by randomness. Over six games, it’s hard to separate the wheat from the chaff. No single player matters that much in the short run. No two players do, even.

I think that both Harper and Schwarber will get slightly more time to rest, though, which brings me to my second reason the Phillies don’t need to be excessively worried about these injuries. The All-Star break starts on July 15 and stretches for four days. Leave both players on the IL until then, and they could get a full 20 days to recuperate without missing an excessive number of games. The Phillies will only play six games between July 8 and July 18; it’s a relatively good time to have your best hitters on the shelf.

Will that cost the team another 0.4 wins in expectation? Sure, I suppose, though I think the actual amount is slightly less than that; Clemens appears at least a little better than replacement level to me. More important than exactly how many wins it costs them, though, is their current position in the standings. The Phillies are up eight games on the Braves. We give them an 81.5% chance of winning their division even after accounting for the dip in playing time for Harper and Schwarber. It’s never great to play with a diminished group, but these games don’t have the same import as they would if the team were locked in a tight divisional race.

When you think about it that way, a rest until July 19 starts to make a lot more sense. It’s highly unlikely that missing two hitters for six games will put Philadelphia’s season on a downward trajectory. The real fear here is some kind of injury recurrence. Soft tissue injuries are prone to re-aggravation, and both Harper and Schwarber have battled injuries in the past, though never of this exact type.

Part of the benefit of roaring out to an early divisional lead is that you can take a pragmatic approach to the rest of the year. Harper is notoriously competitive, and I’m sure he wants to come back as soon as is feasible. His return from elbow surgery in 2023 took less than six months, shorter than even the most optimistic recovery timetable predicted. But now is a good time to be prudent, because one week of games isn’t going to change the team’s season, but a month or two without Harper and Schwarber might.

If I were the Phillies, I’d stick to the more conservative recovery timeline regardless of what happens in the next week. If they’re particularly worried about getting caught by the Braves, though, they could always wait to see the outcome of their series in Atlanta this weekend before making any decisions. If they get swept and neither player experiences any setbacks in their injury recovery, maybe plugging Harper and Schwarber in for those last six pre-break games will become an attractive proposition.

Regardless of exactly how they manage things, though, the Phillies are surely breathing a sigh of relief. Without their two anchor hitters, the team really would look different. The success of their model depends on Harper being a superstar and Schwarber providing valuable offensive backing. For a day, that model got washed away and replaced with the unknown. What if one or even both of these strains were serious? What if something tore? It’s hard to imagine how the team would remake itself without these two, but luckily, it appears that we won’t have to find out for more than a few weeks.

Takeya Nakamura is atypical among NPB hitters. The 40-year-old Seibu Lions infielder not only has 478 career home runs — ninth-most in Japan’s top league — he has fanned 2,118 times. Ingloriously, that is the highest strikeout total in Japanese baseball history.

How is the Adam Dunn-like slugger looked upon in a baseball culture that favors contact over power? I asked that question to Toronto Blue Jays southpaw Yusei Kikuchi, who played alongside Nakamura with the Seibu Lions for eight seasons.

“He’s a former teammate of mine and I really respect him as a player and a human being,” said Kikuchi through translator Yusuke Oshima. “There aren’t a lot of hitters with pop over there. I think those kind of players should be more respected in Japan, because it’s natural for home run hitters to strike out a lot. It’s a tradeoff. He’s said that he’s not worried about it. People should be more open-minded when it comes to those things.”

Kikuchi added that there aren’t a lot of hitters like Nakamura in Japan because “coaches over there tend to frown upon striking out a lot.” Moreover, the statistical categories that are valued most are hits, batting average, runs scored, and RBIs. Pitchers are viewed in a traditionally-similar manner. Much as it once was stateside, wins are what matter most. Read the rest of this entry »

A friend of mine is a huge Cleveland Guardians fan, and the other night we were discussing the awards chances for some of their top players. He pitched Emmanuel Clase as a Cy Young candidate — which, side note: Have you seen his ERA and Cleveland’s record when leading after eight innings this year? — but I was more interested in where José Ramírez and Steven Kwan might finish in the MVP race. I pulled up our leaderboards to see where they stood and was greeted with a surprise that had nothing to do with the Guards:

Huh? Josh Smith? The same Josh Smith who batted below the Mendoza Line in each of his first two major league seasons? The one who didn’t get a single postseason plate appearance last year? The one who barely made the Opening Day roster this season? Somehow, yes.

Through the first half of the 2024 campaign, that Josh Smith has been the most productive hitter in a loaded Texas Rangers lineup. Of course, that doesn’t quite capture how great the 26-year-old has been this season — after all, that loaded lineup is hurt and underperforming — but you could shave 25 points off his wRC+ and he’d still be their best hitter. Fortunately, the Yankees included Smith in their 2021 trade for Joey Gallo, so no shaving is required.

More to the point, Smith isn’t just excellent relative to the Rangers’ band of bangless bangers. Rather, his status as a great hitter this season is indisputable. Here’s where Smith ranks among qualified American League batters:

So what’s behind Smith’s surge? The most obvious thing to point to is his stance. According to Shawn McFarland of the Dallas Morning News, Smith changed his setup and load over the offseason while working out at Texas’ Globe Life Field with Seth Conner, the team’s assistant hitting coach. Smith stands more narrow now than he did last year, and he has gone to a “stacked” load — meaning he keeps his head stacked over the center of his body through his swing to the point of contact. The purpose of these adjustments was to cut down on strikeouts and fly balls, hit more line drives, and get back to the contact-oriented approach that made him a Top 100 prospect a few years ago.

“I decided to change it because I was hitting like a buck fifty,” Smith told McFarland in April. “That was kind of annoying, so I decided to make some changes.”

His actual batting average last year (.185) wasn’t quite that bad, but regardless, if you want to hike up your average, striking out less and hitting more line drives is a good place to start.

Midway through this season, Smith’s changes have worked as intended. His strikeout rate has dropped from 23.7% last year to 19.2% this year, and his 34.9% fly ball rate is down from last year’s 40.4%. Meanwhile, he’s increased his line drive rate by 10.4 percentage points (25.3%, up from 14.9%). That’s the biggest jump among the 188 players who recorded at least 200 plate appearances in both 2023 and ’24:

Smith has said that in his first two seasons, he got caught up in the push for power. He was chasing fly balls because he thought that was the way to stick in the big leagues. In some ways, he achieved what he was going for last year: He dramatically increased his barrel rate (10.5%, up from 2.4% in 2022) and his average exit velocity (88.5 mph, up from 87.0). And last year was an improvement at the plate from his woeful rookie campaign, but that’s like saying the 1963 Mets were better than the ’62 Mets — they were better, but only because they couldn’t get any worse:

During the offseason, in the afterglow of winning the World Series, Smith concluded that he wasn’t going to cut it as a slugger. At 5-foot-10 and 172 pounds, he couldn’t generate enough power to make his 2023 approach worthwhile. So he started working out with Conner and the early returns were promising, as Smith had a good spring training (154 wRC+ in 49 plate appearances). He made the Opening Day roster mainly because of his positional versatility, but he was a backup and playing time wasn’t guaranteed.

That is, until third baseman Josh Jung broke his wrist in the fourth game of the season, requiring surgery. Smith replaced him as the strong side of a platoon but quickly hit his way into the everyday lineup. Beginning with his first start on April 2 through the end of that month, Smith hit .321/.415/.506 across 94 plate appearances, good for a 163 wRC+. He hasn’t looked back since, climbing up the batting order and settling into the no. 3 hole. Even with Jung nearing his return to the lineup, manager Bruce Bochy has said Smith has earned a starting role, though where he plays in the field will depend on the day.

Narrowing his stance and stacking his load have helped Smith get into a better position to hit, but being in a good position to hit and actually doing it are two different things. That brings us to the driving force behind Smith’s success: He’s making much better swing decisions.

Inspired by teammate Corey Seager, Smith has started hunting pitches over the heart of the plate. Sounds obvious, right? Swing at the most hittable pitches. Duh! But that’s easier said than done when you’re in the box and trying to gear up for 100-mph heaters while also worrying about nasty breaking pitches. In Seager, Smith saw the benefits of a selectively aggressive approach and realized he’d been overthinking things in the box.

Now he’s stripped hitting down to its most basic elements to such a degree that I’m cringing while typing this because it sounds like I went to the Crash Davis School of Baseball Clichés: Swing at good pitches, don’t try to do too much, hit line drives. But this really is what Smith is doing. Check this out:

Smith has been especially great at hunting first pitches in the Heart Zone:

This season, nestled in the lineup between Seager and Adolis García most games, Smith is seeing first pitches in the Heart Zone at a much higher rate, and when he does, he’s hacking at and ripping them.

There are some questions about the sustainability of Smith’s breakout. He is greatly outperforming his expected stats (.244 xBA, .350 xSLG, .314 xwOBA), and it seems unlikely that pitchers will keep grooving him this many pitches. But, even if a regression is coming, it’s hard to image that Smith will be as bad as he was in his first two seasons. With his new setup and approach, his foundation as a line drive hitter should help him limit his slumps and produce as a solid lineup contributor, if not the surprising offensive force he’s been this season.

There were a few good reasons for me to catch up with Tanner Houck this past week. One is that he has arguably been the best starting pitcher in baseball over the first half of the season. Along with a 2.18 ERA and a 2.20 FIP, the 27-year-old Boston Red Sox right-hander boasts the highest WAR (3.6) among big league hurlers. Another is that I’ve been due to ask him about the pitch he relies on most. Per Statcast, Houck has thrown 41.8% sliders, 30.8% sinkers, 24.8% splitters, and 2.6% cutters.

Back in 2019, when he was pitching in Double-A, Houck was featured here at FanGraphs in an interview that focused on his sinker. Two years later, a second interview explored a developing splitter that, as my colleague Kyle Kishimoto detailed just over a month ago, has become an especially effective weapon. Which brings us to the here and now. Interested in both how Houck’s slider has evolved and how it plays within his three-pitch arsenal, I approached him to get some answers.

———

David Laurila: How does the slider you’re currently throwing differ from the one you had last year?

Tanner Houck: “It’s a different grip, technically. Last year, I was running up the horseshoe a little too much and not getting as much side-to-side action. This year there is a focus of creating more east-to-west, side-to-side movement with the pitch, as well as on prioritizing throwing it more in bigger situations. It’s my best pitch by far, so I’m leveraging it whenever I can in those big moments.” Read the rest of this entry »
