It’s easy to take a totally nihilistic view of pitching prospects in general. You’ll get your hopes up over a 13-strikeout start at the College World Series, twiddle your thumbs as innings limits and service time shenanigans delay the path to the majors by two years, and be left scratching your head when the pitcher’s UCL gives out anyway, just two months after his big league debut. Next thing you know, you’re watching a 29-year-old, whose coming was once as breathlessly anticipated as the Messiah’s, toodle around for 140 lackluster innings a year.

Such a viewpoint would be facile, the type of cynicism that, to quote the author Joe Klein, “passes for insight among the mediocre.” But baseball fans come by their pessimism honestly; as anyone who’s read a Nick Hornby novel knows, nothing fosters obnoxious nihilism like repeated heartbreak.

MacKenzie Gore was the high schooler with the big leg kick and unreal velocity for a lefty. Then he was arguably the top pitching prospect in baseball. Then he was trade fodder — but still a key component of the deal that brought Juan Soto from Washington to San Diego. And in 2023, Gore was fine. He made 27 starts, threw 136 1/3 innings, and posted a 4.42 ERA. Did he look like a future Cy Young winner? No. Was this worth giving up on Soto and risking sending the franchise into a tailspin? No. But he was competent in a big league rotation, and not all pitching prospects even achieve that. Read the rest of this entry »

Roughly a month’s worth of the 2024 season is now in the books. The American League East looks great. The Brewers and Guardians are standing up for the Central divisions. The White Sox can only beat the Rays, and the Astros somehow can’t beat anyone. Enough time has passed that I feel confident saying all of those things. On the other hand, it still feels too early to be certain about which players are over- or under-performing. But that doesn’t mean our opinions can’t change a bit. There’s enough data to make some educated guesses, so let’s put on our speculation caps. Here are four players — two hitters and two pitchers — who have risen in my estimation over the last few weeks. Tomorrow, I’ll follow up with four players who have gone the other way.

Elly De La Cruz, SS, Cincinnati Reds
I already thought De La Cruz had the potential to be one of the best players in baseball before the season started. Quite reasonably, though, I was worried about the downsides. A guy who struck out 33.7% of the time last year is always risky, and that’s particularly true given how he did it. He swung more often than league average at balls and less often than average at strikes; he also made less contact than average. You can have one of those three things be true, or maybe even two of three if you make up for it elsewhere, but three of three? Yikes. Read the rest of this entry »

Spending money can be a lot of fun, but spending someone else’s money is even better. And that’s exactly what we’re doing today!

About a month into the season is typically when I look at some of the players who are prime extension candidates and the possible deals they might work out with their teams. As usual, the contracts here are not necessarily what I would offer the players or what they will get, but what the mean, cold-hearted projections think would amount to a fair agreement. For each player, I’ve included their ZiPS projections with the latest model updates.

Elly De La Cruz, Cincinnati Reds (Nine years, $192 million)

It’s going to be a long time until Elly De La Cruz is eligible for free agency, but if the Reds wish to signal to the fans that the best players they develop will be in Cincinnati for longer than their middle arbitration years, ownership is going to have to make a real commitment to one of them at some point. And who is a better option than De La Cruz? I would have said Matt McLain a few months ago, but his major shoulder surgery makes it a risky time for both team and player to come to a meeting of the minds on a future dollar figure. De La Cruz still has issues making contact, but his plate discipline has continued to improve since his debut. He’s drawing a lot more walks this year and he’s actually been better than the average major leaguer at not chasing pitches. And with better plate discipline should come more power because a greater percentage of his swings will come against pitches that he can actually drive.

As you can see below, he wouldn’t need to exceed his 50th percentile projections for home runs by much to secure a 40/40 season. In fact, after hitting his eighth home run of the year Monday night, De La Cruz is currently on pace for 45 homers and an absurd 101 steals this season — and he still has a lot of polishing left to do. He’s also showing he’s far from a defensive liability at shortstop, even though a healthy McLain is still probably preferable there. This contract buys out some of De La Cruz’s early free agency years and gives him a big wad of guaranteed dough.

Corbin Burnes, Baltimore Orioles (Eight years, $210 million)

If you’ve been following my work for a while now, you surely know I’m an Orioles fan. And like many other Baltimore fans, I remember the moment when I became unhappy with the ownership of the late Peter Angelos. My feelings toward him soured because of how he and the Orioles handled their free agent negotiations with Mike Mussina. After Moose had previously taken a hometown discount, the O’s assumed he would continue to pitch for them at a below-market rate, and as a result, they lowballed him the next time he was eligible for free agency. He declined, leading to the second-best pitcher in team history finishing his career wearing Yankee pinstripes and ensuring that his Hall of Fame plaque wouldn’t have an ornithologically correct bird on the cap.

While I still think the team should lock up Grayson Rodriguez long term, it’s far more urgent< for the O’s to extend Corbin Burnes, given that he hits free agency after the season. No better pitcher will be available this winter, and nobody in the minors anywhere, for any team, is a safe bet to be better than Burnes over the next five or six years. New owner David Rubinstein has said all the right things, and he made a nice gesture when he bought everyone at Pickles a round of drinks, but the best way to show that he’s serious about building a perennial contender is to not let his team’s ace sign elsewhere. Given the O’s have just about nothing in the way of financial obligations, there’s no reason not to extend him. If that means paying more than that figure above, so be it.

Bo Bichette, Toronto Blue Jays (Seven years, $151 million)

Let’s be clear, despite his uncharacteristic struggles so far this season, I think Bo Bichette will command more than $151 million, and while the Blue Jays may balk any amount greater than that figure, they should still be willing to pay him whatever it takes to keep him around for the bulk of his career. Because of his position and his consistency (again, his first month of this season notwithstanding), Bichette has emerged as the best scion of a baseball family in Toronto, and time’s running out to extend bounty hunter Boba Chette before he hits free agency after the 2025 campaign. I actually think he’ll age better than ZiPS does, at least offensively. Either way, shortstops get super expensive if you wait until they hit the open market. That means that now’s the time for the Blue Jays to extend him if they’re going to keep him, even if that means going over this projected offer to ensure he doesn’t reach free agency.

Alex Bregman, Houston Astros (Four years, $101 million)

The Astros have been able to let some of their offensive contributors walk in free agency — Springer and Carlos Correa among them — mainly because they’ve had pretty solid replacements coming up at the same time, such as Yordan Alvarez, Kyle Tucker, and Jeremy Peña. There’s no similar player on the horizon who can take the place of Alex Bregman. And with Houston already reeling with its pitchers, it would be a lot to ask the front office to fill a gaping hole at third base as well.

Max Fried, Atlanta Braves (Six years, $150 million)

Atlanta has a knack for being able to survive epidemics of pitcher injuries in ways that are fascinating if you’re a fan of the team and maddening if you root for another one. But with Spencer Strider already out for the rest of this season after undergoing internal brace surgery for his damaged elbow, can Atlanta really afford to let Max Fried and Charlie Morton depart this offseason? I like what Reynaldo López has done this season, but you don’t really want to go into 2025 counting on his continued success, Chris Sale’s health, and a full recovery from Strider following his second UCL procedure? The Braves reportedly offered six years, $162 million to Aaron Nola; how could they not make a similar offer to Fried, a similarly valued pitcher who has been a large part of their recent success? Now, all reports I’ve heard suggest Fried’s not keen on discussing an extension during the season, but that doesn’t mean he wouldn’t change his mind if Atlanta gives him a good reason to do so.

Josh Naylor, Cleveland Guardians (Four years, $80 million)

Since the start of the 2002 season, the Guardians have received 10,109 plate appearances from first basemen not named Jim Thome, Carlos Santana, or Josh Naylor. Those 57 hitters have combined to hit .253/.324/.426 for 7.7 WAR, or about 0.5 WAR per 600 plate appearances. This is a franchise that has struggled to find solid fill-in first basemen, so it’s hard to imagine the Guardians would be able to find an an adequate replacement if Naylor walks after 2026. And this is hardly a blockbuster deal; it’s similar to what Kyle Schwarber got from the Phillies coming off the best season of his career (2.7 WAR in 2021). Naylor’s not a superstar, but he’s in his prime years. That should be enough incentive for the Guards to pay for him to stick around, and so long as the deal is fair, the fact that Josh’s younger brother Bo also plays for Cleveland might make him more inclined to stay.

Jackson Merrill, San Diego Padres (Seven years, $95 million)

Jackson Merrill has one of the odder long-term projections according to ZiPS, which expects him to have a long, stable plateau rather than a period of significant growth followed by a steady decline (at least in the years covered below). But ZiPS is increasingly coming around to his reputation as a good bad-ball hitter, and his batting average projections have improved considerably since the winter. Merrill looks to be a solid player, and he’s one the Padres may need toward the end of their long-term deals with infielders Xander Bogaerts, Manny Machado, and Jake Cronenworth.

Pete Alonso, New York Mets (No offer)

Pete Alonso is rightfully a very popular player in New York, and I’ve always had a soft spot for the Polar Bear, both because homers are fun and because ZiPS was in on him very early when he was a prospect (everyone likes looking smart). And with his free agency imminent, this would be a suitable time to extend him on a long-term contract. The problem is, the more I look at the situation, the harder it is for me to think of a scenario in which he and the Mets could come to terms on a deal unless one party was willing to come out of the negotiation feeling very unhappy. ZiPS suggests a four-year, $70 million contract, and I can’t imagine Alonso feeling anything but insulted by an offer like that. I think given Alonso’s place in the organization and the hiccups in the development of Brett Baty and Mark Vientos, the Mets would be willing to pay Alonso more than a projection suggests, but I can’t see them offering him Freddie Freeman or Matt Olson money, either. Because the basic fact is that Freeman and Olson are more well-rounded players than Alonso, who has one amazing dimension. Just to illustrate, below Alonso I’ve included the projections for Freeman and Olson over the next six years.

Alonso projects to be slightly worse than them in the short term and then to be similar in the later years, though that’s likely because he is younger than them. Plus, by the end of 2024, the other players’ contracts already will have covered two additional prime seasons from Olson and three from Freeman. I don’t think any pending free agent has a bigger gulf than Alonso does between the perceived value of his past and the expected value of his future, and as such, this has contract boondoggle written all over it, as big as it was with Kris Bryant a couple years ago. I don’t envy the Mets for the decision they have to make with Alonso, because letting him go, trading him, and keeping him all feel like poor options.

With five hits in a three-game span against the Diamondbacks and Mets, Paul Goldschmidt finally got off the interstate — to use former All-Star-turned-broadcaster Ken Singleton’s memorable term for hitters with a batting average below .200 — but as the end of April approaches, the 36-year-old first baseman has nonetheless produced at a sub-replacement level thus far. It’s early, but he’s got some company in that department among former All-Stars, as well as some high-profile free agents both past and future.

Goldschmidt won the National League MVP award in 2022, hitting a robust .317/.404/.578 with 35 homers; he led the league in both slugging percentage and wRC+ (176) while totaling 6.9 WAR. His value slipped to about half of that last season (3.4 WAR) as he batted .268/.363/.447 (122 wRC+) with 25 homers — respectable by most standards, but the lowest slugging percentage of his 13-year career to that point. Right now, both he and the Cardinals would gladly settle for that batting line, as he’s hitting just .208/.304/.287 with two homers, a 74 wRC+, and -0.3 WAR.

Goldschmidt is hardly the Cardinals’ only hitter who is struggling. Last week, the team optioned Jordan Walker, who was carrying a .155/.239/.259 (44 wRC+) line, back to Triple-A Memphis, but that hasn’t exactly cleared up the problem. Nolan Gorman (77 wRC+) and Lars Nootbaar (81 wRC+) have been terrible as well, and their center fielders, Michael Siani and the since-demoted Victor Scott II, have combined to “hit” .095/.170/.131 (-7 wRC+) en route to a net -1.0 WAR. Small wonder the team is second-to-last in the NL in scoring at 3.57 runs per game. But this dive isn’t so much about the Cardinals as it is about Goldschmidt, whose offensive profile looks as though it has aged 10 years in the past two. After going 3-for-4 with a home run off the Dodgers’ Tyler Glasnow on Opening Day, he went 92 plate appearances (of which just 12 were hits) before collecting his second extra-base hit. He’s up to four now, having doubled both on Wednesday and Saturday. Read the rest of this entry »

When I interviewed Marco Gonzales in spring training 2018, the now 32-year-old Pittsburgh Pirates southpaw was with the Seattle Mariners and about to establish himself as a solid big league starter. We discussed his return to health — he’d undergone Tommy John surgery two years prior — as well as his repertoire. We also touched on his approach on the mound, a subject we’d earlier addressed in a 2014 conversation when he was a St. Louis Cardinals pitching prospect. At the time, Gonzales was your prototypical crafty lefty, and he’s remained just that throughout his career.

The former Mariners’ player rep for the MLBPA has a lot of opinions on the game he’s played professionally since 2013, when the Cardinals drafted him 19th overall out of Gonzaga University. Not surprisingly, the increase in arm injuries is of particular interest, as is the pitch clock.

Gonzales, who has since landed on the 15-day injured list with a left forearm muscle strain, sat down to discuss those topics at Pittsburgh’s PNC Park earlier this month.

———

David Laurila: We talked back in 2018 when you were with the Mariners. Are you the same pitcher now that you were then?

Marco Gonzales: “No. You’re never the same pitcher you were, even if you think you are. You might have a similar identity — you always have an identity as a player — but you change physically, emotionally, mentally. Your maturity on the mound changes. Your thought process changes, and in turn, that changes what you can do on the mound.

“The pitches I throw haven’t added or subtracted, but how I think about them, how they move, and how I’ve used them has changed a lot. Year to year, week to week, there are changes. That’s part of baseball. For whatever reason, sometimes a pitch doesn’t come out the same way it usually does and you have to use it differently, or maybe manipulate it more.” 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.

At 13-16, the Arizona Diamondbacks have started their season with something of a whimper. The biggest reason for that, in my opinion, has been the performance of Corbin Carroll, who’s gone from winning Rookie of the Year and finishing fifth in MVP voting last season to hitting just .189/.295/.236 (60 wRC+) with just one home run over 122 plate appearances. There are a couple of silver linings — he’s swiped eight bases despite his struggles and has struck out just 21 times to go along with his 15 walks — but frankly, it’s mostly been a disaster for a guy who should be playing like what he is: the most talented all-around player on the National League’s reigning pennant-winning team.

Firstly, I’ll acknowledge that Carroll perhaps overperformed last year. His batting average, slugging percentage, and wOBA were all notably higher than his expected marks, and his barrel, hard-hit, and sweet-spot rates were all in the 51st percentile or lower. Then again, his .268 xBA, .441 xSLG, and .370 xwOBA were all at or above the 65th percentile — meaning he still would’ve been solid hitter if those were his actual statistics. Moreover, with his first full season behind him, we could have reasonably expected him to improve his skills, and thus his production, as he gained experience.

So far, that hasn’t been the case. He’s been downright dreadful at the plate.

Carroll’s top-level approach is good: He’s not swinging and missing (80th percentile whiff rate) or striking out (81st percentile strikeout rate), and he’s taking his walks (84th percentile walk rate). But there’s only so much value a hitter can provide by walking and making contact if his quality of contact is abysmal, and, well, that’s pretty much the only way to describe it. His 30th-percentile barrel rate is actually his best quality of contact marker, with his percentiles for average exit velocity, hard-hit rate and sweet-spot rate all amazingly in the fourth percentile or lower. He’s basically hitting the ball with the authority of Steven Kwan and Luis Arraez; that can be totally fine for a hitter if he has the bat control that those two have (which leads to elite sweet-spot percentages), but Carroll doesn’t have that, making him punchless at the plate.

On average, Carroll is hitting the ball nearly five mph softer than he did last year. Along with that, his groundball rate has increased by nearly five percentage points. For Carroll, who has as much speed as anyone in baseball, putting the ball on the ground is far from the worst thing, but that spike in worm-killers has come at the expense of his power. Last season, he hit 25 home runs, 30 doubles and 10 triples; one homer and two doubles are his only extra-base hits this year.

When a hitter loses this much punch despite being in his early-20s, the focus, understandably, will turn to injury. Carroll has a history of scary shoulder problems, forcing him to have surgery when he was in the minors and causing him to leave a couple of games last season after painful swings. But I haven’t noticed any wincing or grimacing in the Carroll plate appearances I’ve seen this year, and he hasn’t been lifted from the lineup because of his shoulder. If there are residual issues, Carroll is keeping them private. Instead, he’s theorized that his working to cut down on strikeouts has created a deeper point of contact, which has made it harder for him to get out in front of pitches and drive them. That’s borne out in the data; his overall pull rate is down from 38.4% to 33.7%, and he’s pulling just 6.5% of fly balls compared to 27.2% last year.

This very well could be the root of his struggles: Carroll doesn’t have otherworldly raw power, so if he’s going to tap into the pop he does have — as he did last year — he’s going to need to start pulling the ball in the air again. If that means taking bigger cuts and whiffing a bit more as a result, then that’s a worthy tradeoff for him to get back to being the offensive force we know he can be.

On George Kirby and Command vs. Control

George Kirby is a fantastic pitcher, and one of my favorites to watch. The degree to which he limits walks is so unprecedented in this era that it’s almost comical. (For what it’s worth, I’m not ashamed to admit I had only so much as heard of 12 of the 24 pitchers ahead of Kirby on the list.)

It’s indisputable that Kirby has incredible control, the likes of which we haven’t seen since most pitchers were topping out at 88 mph instead of 98. If anyone breaks the 20-80 scouting scale for control, it’s Kirby. The question, though, is this: Is his command better than any pitcher since Pud Galvin retired in 1892? I would argue no.

For those unfamiliar, control is accuracy (throwing the ball in the strike zone), while command is precision (throwing the ball where you want). We’ll never know for sure where Kirby wants every pitch; there are command-based statistics that attempt to use catcher glove position to approximate, but with PitchCom allowing for more seamless communication, catchers have an easier time deking hitters who may glance back for location. But it’s hard to imagine he wants all of his sinkers where he’s putting them, even as, in fairness to him, opponents are batting just .172 against that pitch.

But they’re hitting .357 off his slider, and while Kirby’s generally able to locate it down and on the glove side, when he misses with it, he tends to leave it up and over the middle third of the plate to righties.

Pitchers aren’t robots, and even the best won’t be able to put the ball where they want all the time. Many pitchers throw the ball outside the strike zone when they miss their spots; Kirby’s misses happen within the zone. That leads to more balls in play, which makes for a more entertaining viewing experience and oftentimes a lower pitch count, but that doesn’t necessarily mean he has the best command of all time. If his command were that impeccable, considering how good his stuff is, he’d be the best pitcher in baseball by far; instead, he’s allowed nearly a hit per inning this year. Don’t get me wrong: He’s very good, one of the best starters in the league, but let’s not overrate him just because he has a lower walk rate than anyone who’s pitched since Benjamin Harrison was president.

Judge’s Hand Gives Big Inning A Head Start

In their 15-5 win on Sunday, the Yankees had a massive sixth inning that was jumpstarted in the oddest of ways. With the score knotted at four, nobody out, and Aaron Judge on first base, Alex Verdugo bounced a routine double play ball to second baseman Brice Turang, who flipped to shortstop Willy Adames, who came across the bag and fired to first. Except the ball never made it there. Instead, it deflected off the raised hand of a sliding Judge and rolled to first baseman Jake Bauers well after Verdugo reached.

— Talkin' Yanks (@TalkinYanks) April 28, 2024

After discussion on the field, the umpires elected not to call interference on Judge, which would have resulted in a double play. Verdugo was allowed to remain at first base. The next batter, Giancarlo Stanton, popped up to Turang for the second out before the Yankees rallied for seven runs. Interference is a judgment call and thus is not reviewable, but interestingly, crew chief Andy Fletcher said after the game that he believed his crew missed the call, describing the hand raising as “an unnatural part of his slide.”

Crew chief Andy Fletcher said they missed the call on Judge’s slide.

“On the field we got together and did the best we could to come up with a correct answer. After looking at it on replay, it appears that the call was missed. It was an unnatural part of his slide.”

— Curt Hogg (@CyrtHogg) April 28, 2024

Here is the rule that Fletcher said Judge violated, per the MLB rulebook: “If, in the judgment of the umpire, a base runner willfully and deliberately interferes with a batted ball or a fielder in the act of fielding a batted ball with the obvious intent to break up a double play, the ball is dead. The umpire shall call the runner out for interference and also call out the batter-runner because of the action of his teammate.”

So, according to Fletcher, interference should have been called and Verdugo should’ve been out because Judge added an unnatural act to his slide to “willfully and deliberately” break up the double play. Except, the raised hand is a natural part of Judge’s slide. “I’ve been sliding like that for years,” he said after the game. “You can look back at any picture you want of me sliding into second base.”

Indeed, I did go back and look, and I found this 2021 video of Judge sliding into second base with his hand high above his head on a stolen base.

So while this perhaps is unnatural for most, it is completely natural for Judge. Maybe this is something that opponents — and umpires — should add to their scouting report on him.

Jared Jones had made just one big-league appearance when my colleague Ben Clemens wrote on April 2 that we should all get irresponsibly excited about the rookie right-hander. Little has happened to change that opinion. When Jones takes the mound this afternoon for the sixth time in a Pittsburgh Pirates uniform, he will do so with a 2.79 ERA, a 3.19 FIP, and 34.8% strikeout rate. Moreover, his fastball has averaged 97.3 mph, occasionally reaching triple digits.

Following his second start, I caught up to the flame-throwing 22-year-old at PNC Park to get a first-hand account of his arsenal and development path. Among the things I learned is that he was especially raw when the Pirates drafted him 44th-overall in 2020 out of La Mirada (CA) High School.

“I didn’t know how to pitch when I signed,” Jones told me. “I just threw fastballs, and throwing hard in high school is a lot different than throwing hard in pro ball. Guys in pro ball can hit the hard fastball, especially if you don’t have anything else.”

Jones did have secondary pitches prior to getting drafted, originally a curveball “that wasn’t very good,” and then a slider that went from “just okay” as a young prep to “pretty good” by the time he’d graduated. Even so, he was admittedly more thrower than pitcher — someone whose elite arm strength allowed him to “just throw fastballs by guys.”

Velocity came naturally to the now-6-foot-1, 180-pound righty. It also came early. “I was in my sophomore year of high school when I hit 97 [mph] for the first time,” explained Jones. “I’ve been a hard thrower for a long time.” Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the San Francisco Giants. Scouting reports were compiled with information provided by industry sources as well as our 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.

From now on, maybe we should ignore the numbers until Juan Soto is leading the league in walks. Soto has had the highest walk rate in baseball in each of the last four seasons. And he’s close this season! He’s got 21 walks (tied for first) and a 17.4% walk rate (tied for third). But first place belongs to Riley Greene, and that’s a surprise. Greene is not the person you’d expect to top this list. Excepting a two-game stint in Single-A in 2022, he hasn’t run a walk rate above 12% at any stop of his career, but this season, he’s at 19.6%. Since 1903, the largest single-season jump in walk rate by a qualified player in AL/NL history was 10.7 percentage points, by Barry Bonds in 2004. Right now, Greene is sitting on a jump of 11.2 percentage points. He’s also sitting on a 157 wRC+, thanks to a .244 ISO that ranks 22nd in baseball, just behind Soto. Aside from the fact that it’s still April, what exactly is going on?

For the second year in a row, Greene has cut his chase rate, and this year the drop is more than five percentage points. Want to walk more? Not swinging at balls is a great start! But take a look at his swing rate on pitches inside the zone.

It’s down by nearly 10 points! Among all qualified players, Greene has the 12th-lowest overall swing rate, by virtue of being 27th lowest outside the zone and 24th lowest inside it. It’s not just that he’s chasing less, it’s that he’s being much less aggressive overall. With such a big drop on pitches inside the zone, I wondered whether Greene had become too passive. After all, his exit velocity numbers are down a bit, and his 63.2% swing rate on meatballs (pitches right down the middle that you should definitely be swinging at) is 15th lowest among qualified players. However, according to Robert Orr’s SEAGER metric, not only is Greene making better swing decisions than he did in 2023, he ranks 17th in all of baseball (minimum 70 plate appearances). Greene has cut his swing rate in the heart zone by 15 percentage points, but apparently cutting nine percentage points off his swing rate in the chase zone was a worthy tradeoff.

Despite being so much choosier, Greene has improved his contact rate by less than a percentage point, which is somewhat odd. We can see what’s happening when we break things down by pitch type. He has cut his in-zone swing rate by roughly the same amount against all three categories of pitches, but look at the breakdown of his chase rates.

Offspeed pitches are still his biggest problem, but he’s halved his chase rate against fastballs, and cut his chase rate against breaking pitches by a quarter. No one who has seen at least 100 fastballs outside the zone has chased fewer of them than Greene. This helps explain things: He’s making a hair more contact on pitches inside the zone, but his contact rate on pitches outside the zone has fallen by nearly five percentage points. That’s what happens when the pitches you’re chasing are harder to hit. In 2023, fastballs (which run lower whiff rates) made up 37.6% of the pitches Greene chased. So far this year, they’re just 19.2%.

It’s important to keep in mind that a player’s contact rate on pitches outside the zone isn’t necessarily that important. Chasing and whiffing isn’t great, but chasing and making weak contact is usually worse. That’s part of the reason Greene is getting into deeper counts and working so many walks. Even though he’s swinging at way fewer strikes, more of the balls that Greene actually puts into play are coming on pitches in the zone: 83.1%, up from 80.7% in 2023.

Before we end, I would like to take you on a brief detour. I mentioned before that Greene’s in-zone swing rate has dropped more or less indiscriminately. He’s down roughly eight points against offspeed pitches and 10 points against fastballs and breaking balls.

Understandably, opponents have reacted to this by throwing Greene a lot more offspeed pitches. In a somewhat odd side note, Greene is under the impression that he has, in fact, stopped chasing changeups. “Heater in, changeup away,” he told reporters. “It’s almost automatic now. Until I can prove that I can lay off the changeup away, they’re going to keep throwing it. And I feel like I’ve been doing a good job recently of laying off the changeup away.” To be clear, he is swinging at significantly fewer changeups, but only inside the zone (where he’s swinging at less of everything). That is in itself a victory, as offspeed pitches give Greene a ton of trouble, but he’s still chasing them at a nearly identical rate. In 2023, 14.6% of his swings came against offspeed pitches. In 2023, that number is 28.6%. It’s nearly double! His 2023 swing rate is on the left, and 2024 is on the right.

Greene has done a great job of laying off elevated fastballs this season, and he’s also done a better job of laying off low breaking balls. But because so many of his swings are coming against changeups, his swing zone is focused down and away. When he swings at offspeed pitches, he’s worse than ever. He’s running a .158 wOBA and a 50% whiff rate against them, and his 83.5 mph exit velocity against them is dragging his overall EV numbers down. However, because he’s picking better fastballs and breaking balls to swing at, he’s barreling up nearly twice as many balls as he did in 2023.

These are all knock-on effects of the big news. The big news is simple: Riley Greene has slashed his chase rate against breaking pitches and decided to stop chasing fastballs entirely. That’s why he’s walking more, and that’s huge. Even if he never figures out how to stop chasing changeups, this is an improvement. However, we’ve still got a few more days left in April, so I am legally obligated to end by throwing some cold water on everything I just told you. Take a look at the 15-game rolling average of Greene’s walk and chase rates.

In both 2022 and 2023, Greene started out passive, and then got more aggressive over the next couple weeks. Presumably he’ll start swinging more at some point, and presumably Soto will ease back into pole position. But even if Greene’s aggression goes all the way back to his career norms, it’s definitely encouraging that he’s displaying better pitch recognition and a better understanding of the strike zone. It wouldn’t be the worst thing in the world for Greene to get some of his old aggression back, especially if he can keep any of the gains he’s displayed in the past month.

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 »
