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.

With just four (!!!) days to go until the July 30 trade deadline, let’s round up some more news and developments from the last few days and discuss how these nuggets might affect what happens over the next 96-plus hours. Here’s the latest:

Miller Trade Could Be off the Table Following Injury

All-Star closer Mason Miller, the most tantalizing reliever on the market this deadline season, went down with an unfortunate injury this week, making it more likely that he’ll remain with the A’s for the rest of the year.

After pitching a 1-2-3 inning on Monday night, Miller fractured the fifth metacarpal in his left hand. According to A’s manager Mark Kotsay, Miller was getting treatment when “he was reminded that he had a postgame lift to get in. Out of a little bit of frustration, he just kind of pounded his fist down on a padded training table.” Miller was placed on the IL on Thursday, and there is no timeline for his return. While this is certainly better if he hurt his pitching hand, the injury surely depresses his trade value because he won’t be pitching for at least a few weeks. As a result, Oakland would be wise not to move trade this season; he is under club control through the 2029 season, and the A’s were going to move him only if they were blown away by the return package. Now that his trade value is down, the organization would be better off holding onto him and then shopping him around in the offseason, after his suitors have seen him come back healthy.

On July 27, 2018, a piece titled A Conversation With Oakland Pitching Coach Scott Emerson was published here at FanGraphs. Notable about the piece is that a question I’d asked about a particular pitcher, Daniel Mengden, ended up segueing into a variety of related topics. As I noted at the time, Emerson loves discussing his craft.

Six years later, that hasn’t changed. A few days before the All-Star break, I once again sat down with Emerson at Fenway Park. I wanted to ask him about pitch counts — the night before, A’s starter JP Sears threw 114 pitches across 5 2/3 innings in Oakland’s 5-2 win over the Red Sox — and expected our chit-chat would last roughly five minutes. Not surprisingly, we talked a good bit longer. Moreover — again not a surprise — we ended up discussing not just what I’d intended, but other aspects of the art and science of pitching as well.

———

David Laurila: JP Sears threw 114 pitches last night. “What is your philosophy on starters going deep into games in terms of pitch count?

Scott Emerson: “For us last night, he had an extra day of rest, and we’re also going into the break, so he’s going to have some rest there. We wanted him to get through the sixth so we could get to [Austin] Adams, [Lucas] Erceg, and [Mason] Miller. We thought that was our best chance through their lineup.

“As for me, I like starters to go as long as they can and as hard as they can. I don’t think 114 is necessarily that high of a pitch count. I thought he was throwing the ball fine. [Mark Kotsay] and I talked about it, and [Sears] felt good about himself, so we tried to get him through [Rafael] Devers. That was the goal.”

Laurila: Generally speaking, how does a pitcher’s arm action and pitching style factor into it? Read the rest of this entry »

One of my enduring memories of watching the All-Star game as a child — a child who became a baseball fan in a time before high-speed internet, social media, or even interleague play — was learning about all the players I’d been unable to see throughout the regular season. That included the American League and West Coast stars, but also a parade of forgettable pitchers, and yes, it always seemed to be pitchers, from crappy teams.

For some reason, Royals right-hander José Rosado is the guy who sticks out in my mind. Rookie of the Year vote-getter in his age-21 season, All-Star at 22 and 24, done in the majors at 25. If he hadn’t shown up in pregame intros between Justin Thompson and Jeff Cirillo that one time, I might never have been aware of him. Read the rest of this entry »

FanGraphs was at the Futures Game in Arlington on Saturday. In total, 16 pitchers appeared in the seven-inning game. The following are some quick notes on every pitcher who toed the rubber during All-Star weekend’s premier prospect event. Obviously one game isn’t enough on its own to move the needle significantly for any of these guys — they all have a large body of work that can better inform our evaluations — but it’s useful to see whose stuff ticks up when they’re in an environment like the Futures Game and get to let it eat in a shorter burst than they’re accustomed to.

Josh Rojas has turned himself into a plus defender. My colleague Ben Clemens chronicled that advancement last month, citing the Mariners infielder’s improved ability to go to his left as a primary reason for his markedly-better metrics. Exactly what type of adjustments have allowed the 30-year-old third baseman to turn the proverbial corner with his glove? I happened to be in Cleveland when Seattle began a road series against the Guardians on the day Ben’s article ran, so was able to get the answer right from the horse’s mouth.

“It was a matter of adjusting what works best for me reacting to balls left and right,” Rojas told me. “It has to do with my preset. Not getting down too early, not getting down too late. Picking up contact points. Another thing that helps is knowing how the ball usually comes off guys’ bats when certain pitchers are throwing. There is constant communication between me, the pitching coaches, and Bone [infield coach Perry Hill] on what the plan is for the series.”

The preset is what I was most interested in, so I asked the erstwhile Arizona Diamondback — Rojas became a Mariner at last July’s trade deadline — if he could elaborate. Read the rest of this entry »

One of my favorite articles to write is the “you won’t believe how this guy is succeeding” piece. You’ve seen me – and plenty of other writers – break it out over and over again. Maybe it’s a reliever with a weird pitch, or a starter with a blazing fastball who is nonetheless succeeding with secondaries. Perhaps it’s a hitter excelling thanks to a novel approach, or a slugger altering his game to prioritize something he didn’t before. In any case, it’s fun to subvert expectations, and it makes for a good story to boot.

Spare some thought for the players who succeed by doing exactly what you think they’re doing, though. They might not garner as many headlines, but that doesn’t make what they’re doing any less real. I have a specific example of this today, someone I was hoping to write about in the former style. I went looking for the one weird trick that made him tick, but I couldn’t find one. Brent Rooker is succeeding with one extremely normal trick: Every time he comes to the plate, he tries to hit a home run.

Here’s a representative Rooker swing:

Here’s another:

You’ll notice a few things right away. He swings hard – his average swing speed matches Bryce Harper and Matt Olson. He also swings with a pronounced uppercut. Most hitters hit more home runs on high pitches, thanks to the laws of physics. Rooker doesn’t have a single homer in the upper third of the strike zone this year; he’s either annihilating pitches down the middle or lifting low balls over the fence.

There’s no way to say this without sounding snarky, so I’m not going to try: The Oakland A’s, who were supposed to be abysmal, have shocked the baseball world by being merely mediocre. They’re in third place in the AL West, with a full series’ worth of buffer between them and their pursuers. The Angels are suffering the mother of all post-breakup hangovers, and it appears that the Astros have finally been caught by Mephistopheles. Reports say a sinister-looking goateed man has been seen pounding on the door to Minute Maid Park, saying, “I gave you your two World Series, now I’m here for your soul!”

Nothing gold can stay.

The key — or at least one key — to Oakland’s surprising ascent to averageness has been a superb bullpen. Closer Mason Miller has grabbed most of the headlines; some people are saying he’s the best reliever in baseball now. I don’t know if that assertion will hold up over a full season, but the hyperbole will continue until the FIP doesn’t start with a minus sign.

Miller’s emergence has sucked up all the air in the room — insofar as there was ever a ton of air in the room for discussing Oakland’s bullpen — to the detriment of his teammates. So I wanted to highlight Lucas Erceg, who’s been very good this season, and is also kind of weird.

The first thing to know about Erceg is that he was, until very recently, a third baseman. As a sophomore at Cal, Erceg hit .303/.357/.502 with 11 home runs in 57 games, but was ruled academically ineligible the following season, which kicked off a circuitous path to the majors. First: A year at NAIA Menlo College, alma mater of former MLB… standout is probably too strong a word, even if he won a World Series and made an All-Star team… Gino Cimoli. Erceg went in the second round to Milwaukee, becoming Menlo’s highest draft pick ever in the process, and slowly worked his way through the minors with a series of unremarkable batting lines.

In 2021, the Brewers gave Erceg, who’d pitched occasionally at Cal, a shot as a reliever, and by that summer he was good enough to get an honorable mention on Milwaukee’s prospect list. (Even if it was only one sentence in a section labeled “Arm Strength.”)

In 2023, the A’s — who have had some success with converting college infielders into relief pitchers, or who at least brought Sean Doolittle through — purchased Erceg from Milwaukee. This furthers my long-held belief that everyone who plays for the Brewers will one day play for the A’s, and vice-versa. We’d save a lot of hassle by merging the two franchises and having them play on a barnstorming circuit called the John Jaha Highway.

But I digress.

Erceg’s surface stats look pretty pedestrian right now, but about half of his 3.38 ERA comes from one three-run blown save against the Rangers on May 6. At the end of April, he was on a run of nine consecutive scoreless appearances, the last eight of which were also hitless. It’s not as impressive as a hidden perfect game, but Erceg did throw a hidden no-hitter (with 13 strikeouts and three walks on 120 pitches) from April 11 to April 30. I regret not getting to this topic two weeks ago, because I would’ve hammered the “more like Lucas Goose-egg” joke until you all started sending me rotten vegetables in the mail.

Puns and unusual development plan withstanding, there are two things I want to highlight about Erceg: His unusual repertoire and the significant step forward he’s made in missing bats from last year to this year.

As you might expect from a conversion project, there are elements of Erceg’s game that might be considered crude. He’s a hard-throwing one-inning reliever, to start, and even after taking a substantial step forward in this department, his walk rate this year is 11.9%. That’s in the “survivable, but not ideal” bucket for a pitcher, even a reliever.

Nevertheless, Erceg has a legitimate four-pitch repertoire. And this isn’t some fastball-slider guy who has a show-me curveball and a changeup he occasionally throws to opposite-handed batters. He throws four pitches between 18.9% and 30.5% of the time, and while he has specialist offerings to both righties and lefties, he throws his four-seamer and slider against everyone, giving him a three-pitch repertoire against any opponent.

There are 15 pitchers this year who qualify for Baseball Savant’s leaderboards, throw at least four pitches 15% of the time, and have no more than a 20-percentage point spread between their most-used pitch and their least-used pitch. (Erceg’s spread is 11.6 percentage points, the third-lowest of his cohort.) Of those 15 pitchers, 10 have thrown most or all of this season out of the rotation. That makes sense, because the more times a pitcher goes through the lineup, the more pitches he needs.

Here are the five relievers, with the number of pitches they throw, the spread between their highest and lowest pitch usage rate, and the average velocity of their hardest fastball. (Hardest, because all five of these pitchers throw at least two types of fastballs.)

These guys aren’t soft-tossers — Brent Suter came up in the net I originally cast before I narrowed the parameters some — but Erceg is on a different planet, velocity-wise. His changeup is averaging 91.4 mph, which is just 0.3 mph slower than Farmer’s sinker. That changeup is getting knocked around — five of the seven extra-base hits Erceg has allowed this season have come off the changeup, including his only home run — but it’s also missing bats at a rate of 37.5%.

In fact, I’m going to combine arbitrary-endpoint theater and small-sample-size theater to give you a fun fact: Through the weekend, only three pitchers in baseball were running whiff rates of at least 28% on four different pitches they’d thrown at least 49 times: Zack Wheeler, Pablo López, and Erceg.

Now to the really fun part. Erceg has experienced a massive uptick in chase rate, from 23.2% to 31.0%, while at the same time lowering his in-zone swing rate from 62.9% to 56.1% and his in-zone contact rate from 79.3% to 67.2%.

In other words, hitters are swinging less at pitches in the zone, and when they swing they’re not making as much contact. And simultaneously they’re chasing pitches a third more than they did last year. It’s not immediately clear to me why this is happening; Erceg’s in-zone rate is down a couple percentage points, and while his overall opponent swing rate is up, it’s by about two swings at this point in the season. That’s nothing.

As with any reliever performance before the All-Star break, it bears monitoring before we start to count on it going forward. But for now, Erceg is getting whiffs on four different pitches, and is one of the best relievers in baseball both at missing bats and avoiding hard contact. Not bad for a converted infielder, and at best the second-most important reliever on the Oakland A’s.

Below is an analysis of the prospects in the farm system of the Oakland Athletics. 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.

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.

Welcome to another edition of Five Things, my weekly column that highlights strange and often delightful happenings from the last week of baseball. My own baseball watching was a bit stilted this week, for the best possible reason. I went to three Giants games, an exciting event made possible by cheap ticket deals, a friend’s birthday, and some last minute cancellations of non-baseball weekend plans. Two of those games were pretty awful; Blake Snell got shelled Friday night, and then Blake Snell’s replacements got shelled Wednesday afternoon.

The good news is, there’s still *so much* good baseball going on all the time that I had plenty in the tank to write about. You don’t have to look too far to find things to like about baseball these days. We’ve got new holidays, old AL Central rivals, stadium gimmicks, and pure unadulterated velocity. As always, this column is inspired by Zach Lowe’s basketball column, Ten Things (Zach inspired Will Leitch to start his own Five Things column over at MLB.com, in fact).

Three out of every four FanGraphs and RotoGraphs staff members picked the Twins to make the playoffs, with 18 of us predicting them to win the AL Central. (Yes, I was one of them.) And who could blame us? Sure, Minnesota lost Sonny Gray and Kenta Maeda from last year’s division-winning team, but the Twins would also get a full season of Chris Paddack, a revamped and improved bullpen, and — hopefully — a full year of Byron Buxton, Carlos Correa, and Royce Lewis anchoring what looked like a strong lineup.

So, naturally, those plans went awry almost right away. The bullpen has been ravaged by injuries, Lewis hurt himself on Opening Day and will be out for yet another extended stretch, and Correa, who was off to a strong start after recovering from his plantar fasciitis that bugged him all of last year, is now on the IL with a strained oblique. Not helping matters is that Buxton isn’t hitting, striking out 36.1% of the time with an anemic wRC+ of 51. The injuries to Lewis and Correa (not to mention Max Kepler, though his stay looks like it’ll be for the minimum 10 days) have eroded Minnesota’s depth, and Buxton’s poor performance is emblematic of the lack of production from the rest of the lineup.

Entering Thursday, the 6-11 Twins had the league’s third-worst wRC+, at 80, and that’s with Correa’s 165 wRC+ in 44 plate appearances. Young lefties Edouard Julien (99 wRC+) and Alex Kirilloff (151 wRC+) are doing their part, which may make you think (as I did when I started researching this column) that the Twins are awfully exposed against left-handed pitching. But they’re actually doing fine (95 wRC+) against southpaws, with both of those lefties beating up on same-handed pitching, albeit in small samples. Additionally, Buxton’s struggles have not carried over to his 13 plate appearances against lefties, and Ryan Jeffers and Manuel Margot are also hammering them.

You probably know where this is heading, then. The Twins are horrible against righties (76 wRC+). In fact, the bumbling White Sox (73 wRC+) are the only team that has been worse against righties than Minnesota. Buxton has a 31 wRC+ across 48 plate appearances vs. righties, and Willi Castro’s 50 wRC+ against righties would look good only in comparison to the marks of some of his teammates and because it is significantly better than his -24 wRC+ vs. lefties. Meanwhile, Margot, Christian Vázquez, and Kepler have all been essentially useless against righty pitching, with wRC+ numbers below zero.

So, what exactly can the Twins do? It’s an uninspiring answer, but not much. Correa and Lewis won’t be back anytime soon. Buxton is going to be given every chance to swing his way out of his slump, and as long as he stays healthy, the Twins should be cautiously optimistic that he’ll turn things around. Aside from that, their best hope is that Kepler will be much more productive when he returns from his knee contusion, which may well have affected his hitting. Matt Wallner was optioned to Triple-A after starting his season terribly (2-for-25 with 17 strikeouts), and surely there’s hope that he’ll come back looking more like the guy who had a 144 wRC+ in 254 plate appearances last year. Otherwise, there won’t really be any saviors rising up from within. Austin Martin is already up in the majors, and Brooks Lee hurt his back and has yet to play a minor league game this year. The Twins will have to make due with what they have until guys get healthy or they find a way to swing a trade or two sometime this summer. In the meantime, it’s not looking great.

Meet the Mets’ Breakout Reliever

Early season leaderboards are always fun, and in just about all cases they shouldn’t be viewed as indicative of what’s to come for the remaining 90% of the season. But that doesn’t mean we can’t take note of surprising players at or near the top of them. So, who leads all relievers in strikeout percentage? The resurgent Craig Kimbrel? The hellacious Mason Miller? Nope, atop the list is Reed Garrett, who didn’t even make the Mets’ Opening Day roster. He wasn’t even one of the last cuts; he was optioned on March 15, a full two weeks before the season started. But since getting the call on April 1 he’s been nearly unhittable, with a ridiculously low wOBA allowed of .177.

Garrett, 31, put up a 7.11 ERA in 44.1 MLB innings before this year, and there wasn’t really anything that we were publicly aware of that made anyone think a breakout was coming. But it’s not hard to see where Garrett’s success has come now that we’ve got the data. He’s deemphasizing his two fastballs, throwing his four-seamer and sinker a combined 26% of the time, with his sweeper, splitter, and slider giving hitters fits.

The splitter — which he’s nearly tripled in usage since 2022 — has been especially lethal, with two-thirds of swings against the pitch coming up empty. The radically different pitch mix makes for changes that look sticky and should allow Garrett to continue his rapid ascent up the bullpen hierarchy. Once viewed as an up-and-down pitcher by virtue of having an option remaining, he looks here to stay.

Leiter Gets Lit Up in Poor Debut

Well, not every MLB debut can go swimmingly. Jack Leiter’s first game as a Ranger started off well enough, with two strikeouts in a scoreless first. But the wheels came off soon after; he allowed four runs in the second and three more in the third and his day ended after just 11 outs.

To my eye, the stuff looked just fine, with his fastball up to 98 mph and averaging 96, but he just didn’t have feel for his offspeed pitches. Hitters really weren’t fooled overall. His 28% CSW rate was right at league average, but it was only 21% on his curveball, slider, and changeup, which made up 47 of his 85 pitches.

Whether Leiter sticks around in the rotation remains to be seen. The Rangers already have six healthy starters as it is, and Cody Bradford’s IL stay should be a short one. And let’s not forget that Tyler Mahle, Max Scherzer, and Jacob deGrom are all lurking for returns later in the season as well.
