The Boston Red Sox beat the New York Yankees 9-7 on Friday night, and regardless of which team you might have been rooting for, the game was an absolute gem. The lead changed hands fives times, the 28 combined hits included four home runs — one of them a titanic 470-foot blast by Aaron Judge — and the tying runs were on base when Kenley Jansen recorded the final out for his 440th career save. Moreover, the atmosphere at a packed Fenway Park was electric throughout. It was as close to a postseason atmosphere as you will find in July.

The loss was New York’s fifth in sixth games, so I was admittedly a bit apprehensive about asking Aaron Boone a particular question prior to yesterday evening’s affair. I did so anyway. Prefacing it by relating a press box opinion that it had been as entertaining as any played at Fenway all season, I wanted to know if, as a manager, he allows himself to think about the aesthetics of a baseball game in that manner.

His answer didn’t disappoint.

“I always try to have a little appreciation for that,” Boone replied. “Especially with what we’ve been going through as a club. We’ve struggled. There are a handful of games where I’ve felt that way, like, ‘Man, this is a really good baseball game going on.’ When you come out on the bad end it kind of sucks, but you try to have that appreciation for ‘That was a really good one.’ Hopefully we can start to be on the right side of those.” Read the rest of this entry »

After a somewhat slow start to this year’s trade deadline, one of the better pitchers available has a new team, with Zach Eflin heading from Tropicana Field to the land of Old Bay and Natty Boh. (That’s Baltimore, for those of you unfamiliar with properly seasoned shellfish and/or nostalgic mass-market budget lager.) Heading back to the Rays from the Orioles are three prospects, right-handed starter Jackson Baumeister, infielder Mac Horvath, and outfielder Matthew Etzel. In his second season with the Rays, Eflin has a 4.09 ERA and 3.65 FIP over 19 starts, good for 1.8 WAR.

Entering the season, the depth of Baltimore’s rotation was something of a concern. Acquiring Corbin Burnes in his walk year did a lot to alleviate the situation, and with the seventh-best ERA and 10th-best WAR in baseball, the rotation hasn’t really hindered the Orioles’ quest to win their first World Series trophy since I was just a wee cynical kindergartener. Still, despite their positive starting pitching rankings, the water has gotten pretty choppy. Both Kyle Bradish and John Means underwent Tommy John surgery in June, and Tyler Wells is out for the season after an internal brace surgery on his UCL in . Further complicating matters is the fact that Cole Irvin, a pleasant surprise in the season’s early going, had a worse June than the Soviet army in 1941. Cade Povich was decidedly mediocre in his debut and was optioned to Triple-A earlier this month, and Chayce McDermott still has command issues to iron out. The team has good reason to expect more from those two in the future, but that future isn’t going arrive this week, and the team needed a bit more certainty in the rotation behind Burnes and Grayson Rodriguez.

I updated the Top 100 Prospects list today. This post goes through the pitchers and why they stack the way they do. Here’s a link directly to the list, and here’s a link to the post with a little more detail regarding farm system and prospect stuff and the trade deadline. It might be best for you to open a second tab and follow along, so here are the Top 100 pitchers isolated away from the bats. Let’s get to it.

This has been a relatively down year for the no-hitter. Entering play yesterday, Ronel Blanco’s masterpiece during the first week of the season was the only no-no of the season, a far cry from the first half of 2021, which saw six solo no-hitters in 41 days, along with the ever-increasing number of combined efforts in the modern era. And while the rookie Blanco was the unlikely hero in baseball’s first no-hitter of 2024, it was an established star who broke the nearly four-month drought: Dylan Cease.

We haven’t written about Cease since his blockbuster trade to San Diego, so let’s check in on his debut season with the Padres. By most metrics, he’s taken a leap forward with his new team. His 32.5% strikeout rate and 7.6% walk rate are both the best of his career, the latter mark a huge development from someone who’s always run a walk rate in the double digits. Both PitchingBot and Pitching+ view 2024 as his finest season; his 3.03 FIP and 3.01 SIERA are also personal bests, and his 3.50 ERA sits behind only his mark in 2022, when he finished as the AL Cy Young runner-up.

CJ Abrams is one of the blossoming stars in today’s game. Entering play Friday, the 23-year-old shortstop who recently made his first All-Star appearance is batting .260/.333/.467 with 15 home runs, 16 stolen bases, a 122 wRC+, a .344 wOBA, and 1.9 WAR over 422 plate appearances. During the first month of what’s turned out to be his breakout season, I wrote about Abrams’ stellar offensive start. About a month-long slump followed, but he bounced back in late May and is showing that his plus-offensive profile is here to stay.

Now in his third season, Abrams is proving he can be the centerpiece that the Nationals can build around. Beyond his bat, his aggressive baserunning and speed make him one of the most dynamic young players in the game. Last year, despite his inconsistencies at the plate, Abrams was a menace on the paths. Thanks to his 28.6 ft/sec sprint speed (82nd percentile), according to Baseball Savant, he was worth +3 runs on the bases; he swiped 47 bags and had a 9.2 BsR.

This year, Abrams has been just as fast, but at least according to BsR, he is no longer a plus baserunner. (Baseball Savant says he’s been worth +1 run on the bases this year, which ranks 71st; he was no. 23 on last year’s leaderboard.) That’s because he’s been caught stealing 10 times already, with five of them coming via pickoffs, plus another pickoff that didn’t come on an attempted steal.

In 2023, Abrams went 47-for-51 on stolen base attempts. If he took off, the odds were in his favor. Pitchers weren’t exposing him for taking too big of leads or being overly aggressive. This year, his precipitous drop to 16-for-26 has been staggering. When a player who was so recently a great basestealer runs into a slump like this, it warrants a deep dive into understanding what exactly is going on. There are a few components of the steal that we have to pay attention to when trying diagnose this type of issue: the lead, the jump, and the situation. Let’s go through each piece and find out what’s gone wrong for Abrams. Here is a compilation of his pickoffs this year:

None of these look particularly great. He was either off balance or out by a good margin on almost every play. We can trace some of this back to his leads, so let’s start there. There are two main ways to take a lead against a lefty if you are thinking about attempting to steal second. You can take a normal 12-foot lead like Abrams did against Sean Manaea and then run on the pitcher’s first movement (as soon as the pitcher lifts his leg). Or, you can take a larger, one-way lead to possibly draw a throw over and get a feel for the pitcher’s pickoff move.

For the first one, you want to stay close enough to the bag so the pitcher doesn’t pick you off, but you want to get far enough out there that you have a good chance to be safe at second even if he does throw over; as soon as the pitcher lifts his leg, you break for second. For the one-way lead, you are an extra step or two toward second, but you are not attempting to steal on the upcoming pitch. Instead, you put all your weight on your left foot, toward first base, so you can dive back safely if the pitcher attempts to pick you off. If the pitcher doesn’t throw over, you are timing up his delivery so you can get a better jump if you decide to steal later. That doesn’t appear to be what Abrams was doing in the video above. All three times he has been picked off by a lefty this season have come early in the count, twice on the second pitch of the plate appearance and once on the first pitch.

In the 1-0 count against Manaea, Abrams took a standard 12-foot lead. He attempted to go on first movement but realized he would’ve been dead to rights, so he hesitated into shuffles instead. He should have just kept going and forced Pete Alonso to make a play. This was the most obvious mental mistake of the three. Against left-handers Kirby Snead and Alex Vesia, Abrams went on first movement, but because each pitcher expected him to go and was well-prepared to throw over, the defense caught him easily. As a pitcher, you know Abrams is an aggressive runner, but why in these two cases was it so easy? Well, this is a good time to point to Abrams’ tendencies.

Eight of his 16 swipes this season came on the first pitch, and of his six pickoffs, four were on the first pitch. If you’re a pitcher looking to control Abrams’ aggression, do it early. For lefties, it’s even easier to execute because you’re facing him as he leads off first. This goes back to the situational aspect I brought up before. Pitchers are smart, and these are the exact types of tidbits they become aware of as they prep for a good basestealer. Combine the early counts with pitchers being more willing to throw over if they haven’t yet used their allotted disengagements, and you have tough recipe for success. A potential solution here is for Abrams to wait for deeper counts before trying to steal.

The right-handed pitchers in these clips are equally prepared for Abrams to run early. He often uses the vault lead against righties. As a reminder, the vault lead is when you take your primary lead at about nine or 10 feet instead of 12. You take your same athletic stance and shuffle about 2-3 feet just as the pitcher lifts his leg. The momentum from your vault helps you accelerate into your sprint quicker than you would with a traditional, static lead, albeit with risks. The key to a successful vault lead is not the size of your shuffle; it’s your timing. If you venture too far out before or after the shuffle, or you mistime your vault and are in the air when the pitcher disengages to throw over, you risk getting picked off.

At times this season, Abrams has made both mistakes on his vault leads: Either his primary leads or his shuffles are too large. The vault lead is more technical than physical, based more on mechanics than reflexes and pure speed. Abrams is fast enough and reacts quick enough to steal bases with a traditional lead against favorable matchups, so if I were him, I would temporarily abandon the vault lead and work on getting the fundamentals down again before bringing it back in games.

Before letting you go, I also want to look at the plays on which Abrams was thrown out by a catcher to see if these caught stealings were because of bad decisions, poor jumps, or good defense. Here is a quick reel:

Off the rip, there are three plays that stick out. If you’re going to attempt steals against Gabriel Moreno and Patrick Bailey – perhaps the two best throwers in the sport – you have to pick your spots wisely. In the Arizona game, the Nationals were up two runs and the count was 0-2, providing a good opportunity to run and try to avoid a double play; against the Giants, my guess is he wanted to get into scoring position with two outs. These are valid enough reasons to run despite the poor matchups and are not comparable to the pickoff mistakes.

In the game against the Red Sox, righty Brayan Bello, who has an extremely quick slide step, was on the bump. Even runners who are faster than Abrams would have trouble reaching second safely when a pitcher delivers a 96-mph heater in the middle of the zone on a slide step. And perhaps not surprisingly, this came on the first pitch of the at-bat.

On the first play in the clip, against the Rockies, Abrams attempted to swipe third with a left-handed batter up. Even without seeing the quality of the lead that Abrams took, this was a bad decision. Dakota Hudson never took his eye off of Abrams before he delivered his pitch, making it much more difficult for him to get a good jump. On top of that, catchers love when this happens because with a lefty batting they have a clear throwing lane to third base; when righties are hitting, catchers have a more difficult play because they need to step back and around the batter before firing. Even with an inaccurate throw from catcher Jacob Stallings, Abrams was canned.

Abrams is an aggressive runner. Without his aggressions, he wouldn’t be able to steal nearly 50 bases in a season like he did last year. This isn’t something you want to take away from him. However, he does need to learn from these mistakes so he can use his speed and aggression more effectively. Most of these pickoffs and unsuccessful steals resulted from some a combination of being predictable and getting too jumpy. The good news is he is talented enough to make the necessary adjustments. Once that happens, we’ll get to see a much more complete version of Abrams, one who can swipe 40 bags at a high clip and pepper the gaps with line drives.

The Mariners have suffered through a pretty terrible stretch over the last five or so weeks. After blowing a 10-game lead in the AL West during a 24-game span — the quickest that any team has ever surrendered such a large divisional lead — they enter play Friday a game behind the first-place Astros and 3.5 games out of the final AL Wild Card spot. Over their last 30 games, they’ve gone 10-20 and have scored a measly 3.4 runs per game while their pitching staff has allowed the fewest runs in the American League. Things got worse earlier this week, when they were swept by the Angels and lost both Julio Rodríguez and J.P. Crawford to injuries. Rodríguez sprained his right ankle and there is no timetable for his return; Crawford, who fractured his right pinky, is expected to miss 4-6 weeks. Even before those two core pieces of the beleaguered lineup landed on the injured list, Seattle desperately needed an infusion of talent onto their roster.

With that need exacerbated by those two injuries, the M’s wasted very little time making their first addition ahead of Tuesday’s trade deadline: On Thursday night, they acquired outfielder Randy Arozarena from the Rays. In exchange, Tampa Bay received minor league outfielder Aidan Smith (40 FV), right-handed pitcher Brody Hopkins (45+ FV), and a player to be named later. Dan Szymborski put together a hypothetical version of this trade just a few days ago and nailed all the broad strokes: The Mariners got the offensive upgrade they needed and the Rays got some really interesting prospects that they can now sculpt.

The former AL Rookie of the Year and All-Star got off to a agonizingly slow start to the season; through the first month of play, he was slashing .143/.220/.241 with three home runs, a strikeout rate just a hair below 30%, and a 37 wRC+. He started to pull himself out of his slump in May (104 wRC+) but was still underperforming. Since June 1, though, he’s been one of the hottest hitters in the league, putting together a .284/.397/.507 slash line with seven home runs and a 161 wRC+ across 179 plate appearances.

As Jay Jaffe noted back in April when he checked in on Arozarena’s woes, and then again during his replacement level killers series last week, “Rays hitting coach Chad Mottola had expressed the belief that Arozarena’s desire to use the whole field more often, in an effort to make himself an even better hitter, may have backfired.”

That change in approach might be related to his diminished contact rate early in the season, particularly on pitches in the strike zone.

His rebound in June and July aligns pretty clearly with his ability to put the bat on the ball when pitchers leave their pitches over the plate. And thankfully, almost all of his other plate discipline metrics are either improved or within range of his established norms.

He’s still making excellent swing decisions at the plate — his SEAGER is in the 84th percentile among all batters this year — and his batted ball metrics are as solid as ever. That two-month funk to start the season is dragging his overall offensive line way down, but make no mistake, it certainly appears as though Arozarena has put those struggles behind him.

He’ll immediately slot into the middle of the Mariners lineup as their regular left fielder and will give them a potent bat to help protect Rodríguez whenever he returns while providing dynamic run production himself. Perhaps more importantly for Seattle, Arozarena won’t reach free agency until 2027; he’s making $8.1 million this season, his second year of arbitration. The organization has developed a mostly homegrown rotation that has emerged as one of the best in the majors, but over the last few years, the Mariners have been reluctant to use free agency to improve their lineup. That makes it imperative for the front office to be aggressive on the trade market to acquire impact batters who can help the Mariners not just this season but throughout this competitive window, before their group of pitchers either breaks down or becomes too expensive to keep together. Arozarena boosts this lineup now and in the future.

For the Rays, this trade comes at an interesting time. They’re actually only a half game behind the M’s in the AL Wild Card standings and their pitching staff is getting a lot healthier. Shane Baz just came back from his Tommy John rehab earlier this month, Jeffrey Springs should be returning to the majors within a week or so, and Drew Rasmussen isn’t that far behind Springs. Tampa Bay has been hovering on the edge of the AL playoff picture for nearly the entire season, but a late-season surge wouldn’t have been out of the question. By moving Arozarena at this point in the season, the Rays have indicated that they’re more interested in ensuring they’re set up well for the future than in hoping for a long-shot playoff run over the next few months.

The timing also says a lot about what they think of the prospects they’re getting in this deal. Arozarena’s escalating salary now that he’s in the middle of his arbitration seasons had made him an obvious trade candidate this year, but the Rays could have waited until the offseason to move him if they didn’t like the players they were getting in return. That they acted now indicates they liked this package enough to pounce on it five days before the trade deadline. On the very fresh Mariners prospect list that Eric Longenhagen recently put together, Hopkins was ranked seventh and Smith 21st.

In a Seattle organization that is notorious for helping pitchers develop into the best versions of themselves, Longenhagen called Hopkins the most exciting pitching prospect in the system. He’s a converted outfielder who was selected in the sixth round of last year’s amateur draft and is still very new to pitching. He’s got a low-slot release with some deception in his mechanics, and that arm slot creates a ton of ride and life on his mid-90s heater and gives him a wipeout slider that flashes plus. He still needs to develop a third pitch to flesh out his repertoire to reach his ceiling as a mid-rotation starter, but even if he doesn’t, he appears to have a pretty nice floor as a two-pitch high-leverage reliever. He’s already 22 years old, which makes him pretty old for Single-A, where the Mariners had placed him in their organization, but as he gains development time as a pitcher, he should move quickly up the ladder.

As for Smith, he was Seattle’s fourth-round pick in last year’s draft and has hit very well in his brief professional career. A prep selection out of Texas, he’s an athletic outfielder with plenty of speed to stick in center field. He was slashing .284/.402/.470 at Single-A Modesto, and it looks like he had made the necessary adjustments to his swing to improve his feel for contact. He’s a ways away from the majors, but his physical projection and successful start to his minor league career were both intriguing enough for Tampa Bay to take a chance on him.

Even with Arozarena in the fold, the Mariners should not be done adding to their roster. Their offensive issues are too deep to be solved by one player. Even after moving Hopkins and Smith, Seattle has enough highly regarded prospects available to move for another big splash. They’ve been linked to Jazz Chisholm Jr. and Vladimir Guerrero Jr. over the last few days — both would be significant upgrades to the black holes the Mariners are running out at second and first base this year. Given the Mariners’ place in the standings and the state of their roster and farm system, this move for Arozarena should not preclude them from continuing to improve their offense over the next few days.

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 »

The Milwaukee Brewers, in recent history, tend to be a little light both on offense and in the payroll department. Which makes Christian Yelich — the team’s leader in batting average, on-base percentage, and slugging, and the recipient of nearly a quarter of the team’s major league salary expenditure — a pivotal figure for the franchise. Perhaps to an extent unmatched by any other position player on a contending team. (That’d be an interesting blog for another day.)

On Tuesday, the Brewers faced a situation tailor-made for Yelich: Leading 1-0, runners on first and second, two outs, the right-handed Julian Merryweather on the mound. Milwaukee had struggled to scratch out even that one run, and just a single by Yelich would’ve given the Brewers bullpen room to relax. And yet, out of the dugout stepped the right-handed Rhys Hoskins, not Yelich. Hoskins struck out, and the Brewers quickly announced that their star left fielder was experiencing back tightness.

Oh, crap. Read the rest of this entry »

“An egregious error of Umpire Hurst in construing the rules helped Boston to two runs and added to the confusion of the Orioles. In the fourth inning Boston had three men on bases and one out. Ryan came to the bat and scratched out a short fly over third base. Jennings ran for the ball, got under it and muffed it. According to Rule 45, Section 9, a batter is out ‘if he hits a fly ball that can be handled by an infielder while first base is occupied with only one out.’ Ryan should have been declared out whether the ball was muffed or not…

When seen at the club-house after the game he started in defense of his position by attempting a distinction between the outfield and infield, claiming that the ball was not hit to the infield, but when his attention was called to the wording of the rule, which does not state that the ball must be hit to the infield, but simply that it shall be such a ball as an infielder can handle, he abandoned that position, and argued that it was not a fly ball, but a line drive. He soon saw the absurdity of that argument, as a line drive which does not touch the ground is as much a fly ball as if it were hit 100 feet up into the air.”

– “Errors Lost the Game,” The Morning Herald, April 26, 1894

The graph below has been haunting me for weeks now. I made it, but there’s nothing unique about it. You can find an identical graph in this Alex Chamberlain piece, this Tom Tango blog post, or any number of other articles. It shows the batting average and wOBA for every batted ball, based on launch angle.

I cut off 20 degrees from either side, but you get the point. Worthless groundballs and popups are on the sides, and valuable line drives and fly balls make up a narrow sliver in the middle. It occurred to me a few weeks ago that we’ve been splitting batted balls into those same four categories for a very long time now. Moreover, one of those categories is suspect. If you’ve been reading FanGraphs for a while, you know that line drive rate is considered fluky rather than sticky. Only a handful of elite players – Luis Arraez, Freddie Freeman, maybe Steven Kwan – are capable of consistently putting up top-10 line drive rates. According to Baseball Savant, batters have a .639 wOBA on line drives this year. Hitting line drives is what every single batter is trying to do, and yet somehow what Russell Carleton wrote seven years ago still holds true: “There is some skill in hitting line drives, but it is hard to repeat, and how many line drives you hit seems to be unrelated to where you fall on the ground-ball/fly-ball spectrum.” I set out to find some new way to look at this old puzzle, figuring that with all of the tools as our disposal, there had to be a better way to slice this particular pie. I failed, but I came across some interesting things along the way, and that (I have decided after the fact) is what’s really important. Read the rest of this entry »

We now have less than a week until the the July 30 trade deadline, and so far, not much has happened other than the Hunter Harvey trade before the All-Star break. That ought to (hopefully) change in coming days, unless we’re witnessing the heat death of the baseball universe.

As is my habit, I have suggested eight trades that teams should to consider in some form to fulfill their short-term and long-term organizational goals. I’ve tried to make broadly fair proposals in the context of historical deadline trades, but your mileage may vary. Please note that I am not reporting these as trades that are currently being discussed by respective front offices, and if you report these as such, you hereby waive all rights not to receive an ironic visit from an antagonist from a German fairy tale.

Let us know what you think about these ideas and feel free to add your own in the comments!

The Baltimore Orioles acquire P Garrett Crochet from the White Sox for 3B/1B Coby Mayo, OF Enrique Bradfield Jr., and P Chayce McDermott

I know the White Sox are dreaming of a mega-package in return from Garrett Crochet, who is a legitimate Cy Young candidate this season, but I just can’t see them doing better for Crochet than they did for Dylan Cease. I would argue that Coby Mayo, if he had been included in the Cease trade through some kind of weirdness in the space-time continuum, would have been the most valuable prospect involved, more so than Drew Thorpe was at the time. I’m sure the Sox would prefer a comparable pitching prospect to Mayo than Mayo, but I’m not sure the teams most likely to go after Crochet have that available. Mayo is likely to be an impact bat, even if he isn’t going to stick at third base. He also should to be able to contribute quickly, which appears to be (confusingly) an important goal for the White Sox, even though they are in a generally worse position than they think they’re in.

The White Sox may counter and say that they expect a return similar to the Chris Sale trade, but I can’t imagine any team doing that. Sale at the time was a much more established pitcher than Crochet is currently, and he also wasn’t a year removed from a significant elbow injury, as is the case with Crochet. The O’s are in a situation in which they can justify being even more aggressive than this, but to include more name brand talent than this starts to make the trade look quite a bit riskier. Enrique Bradfield Jr. and Chayce McDermott are ranked seventh and eighth, respectively, in the Orioles’ system — 45+ FV guys but not Top 100 Prospects. I do get the impression that at the end of the day, the White Sox don’t have to be completely bowled over to trade Crochet, while the Tigers may very well need to be for Tarik Skubal, the best lefty pitcher who might be available.

The Houston Astros acquire 3B/1B Isaac Paredes from the Tampa Bay Rays for OF Jacob Melton, SS Alberto Hernandez, OF Luis Baez, and P Alimber Santa

Corner infielder Isaac Paredes is arguably the best bat likely to be available at the deadline, so it’s hard for the Astros not to have serious interest given the utter wreck that first base has been for them this year (.205/.276/.317). While one of the prime artisans of that triple-slash, José Abreu, is gone, Jon Singleton is not much of an improvement, and at 32, he’s hardly the future of the position. Paredes, who has three years left until he hits free agency, would fill that short-term need at first and also provide the Astros with an option to replace third baseman Alex Bregman if he doesn’t re-sign with the team.

While Houston has reasons to be interested in Paredes, do they have enough to offer? I think that’s the key question here, because the farm system is pretty poorly stacked at the moment. I don’t think there’s any way the Astros can pull off this trade without giving up their top prospect Jacob Melton, who is ranked no. 78 overall, or Jake Bloss, their top pitching prospect and no. 100 on our Top 100 list. Even if one of those two are included, the Astros would have to send along a few other guys who offer enough upside to make it a worthwhile deal for the Rays. I kinda see Alimber Santa as one of those hard throwers with poor command that the Rays suddenly make into elite relievers after a midseason call-up. I could also see the Rays asking for Shay Whitcomb, who fits in with their organization’s long-term embrace of unheralded Joey Wendle-type infielders who hit in the upper minors and get no attention around the league. ZiPS has actually been rather enamored with Whitcomb for a while. The Rays have bled a lot of outfield bats over the last few years and, in addition to Melton, Luis Baez would help them restock. On top of that, Tampa Bay likes upside, and while I’m a José Caballero fan, Alberto Hernandez certainly has upside. With Jeremy Peña and Jose Altuve, Houston can spare middle infield prospects, even really good ones.

The Los Angeles Dodgers acquire RHP Jack Flaherty from the Detroit Tigers for LHP Justin Wrobleski and SS Trey Sweeney

The Tigers are no doubt asking for the moon for Skubal, but they don’t have the same need to do so for Jack Flaherty, a free agent at the end of the season. Flaherty’s been terrific this year, but he’s also a rental, and teams don’t usually give up their best for players on expiring contracts these days. I kinda wanted to center this trade around one of the Dodgers’ many young catchers, probably Thayron Liranzo, or an infielder on the rise like Alex Freeland, but that just seemed a bit too rich for them to give up for two months of Flaherty’s services. The good news is the Dodgers have an extremely deep farm system, so if a trade like this were to be discussed, there are myriad ways to get Detroit interested, even if it’s not exactly these two mid-tier prospects. Justin Wrobleski is probably too much of an innings eater for the Dodgers, who prefer to juggle high-end pitching talents based on who’s healthy, and although Trey Sweeney has been passed by other players in the organization, the Tigers could still use him in their system.

I think it would be a mistake if the Dodgers didn’t add a pitcher before the deadline. Yoshinobu Yamamoto’s goal to make it back before the playoffs is not an auspicious sign, and even with Clayton Kershaw and Tyler Glasnow returning from injuries, I think the team would be well-served to have another fairly hardy pitcher in the mix for the playoffs.

The Seattle Mariners acquire 1B Yandy Díaz and OF Randy Arozarena from the Tampa Rays for RHP Logan Evans, RHP Emerson Hancock, and RHP Michael Morales

This trade depends on the status of Yandy Díaz, who is currently on the restricted list for a personal issue, but I’m assuming that will be resolved fairly soon. If not, then I’d still be in favor of a scaled back trade in which the Mariners acquired Randy Arozarena. Rays fans might be underwhelmed by the lack of a huge name coming back in the deal, but I don’t think Díaz and Arozarena really have the same trade value they had a year ago, and we project both players to finish with just short of two WAR for the 2024 season. But I think they each hold decent value for the Mariners considering how bad their offense has been this season. The Mitch Haniger reunion hasn’t worked out, and first baseman Tyler Locklear is likely a worse hitter in the short term than Díaz. Additionally, both Díaz and Arozarena have some cost control remaining. The Rays like interesting pitching prospects the way that sculptors like marble, and the M’s are one of the few teams that can provide them without impacting to their long-term roster. Three of those interesting lesser pitching prospects are righties Logan Evans, Emerson Hancock, and Michael Morales. Paredes would probably be an even better pickup for the Mariners, who really need a bat, but I already gave Paredes to the Astros.

The St. Louis Cardinals acquire RHP Nathan Eovaldi from the Texas Rangers for RHP Sem Robberse and C Pedro Pagés

I’m still unsure what the Rangers plan to do next week, but should they decided that retooling isn’t a dirty word for them, Nathan Eovaldi is one of the logical players to trade. Technically, he has a vesting player option for 2025 at $20 million, but I’m not sure that’s really a factor here; Eovaldi’s on target to meet the 300 innings requirement should things go well this summer, and if they do, he’ll be in a position to do a lot better than a single year at $20 million. Like Flaherty, there are no moons to acquire for two months of Eovaldi, but I think the Rangers could do a lot worse than two mid-tier prospects who aren’t years away from the big leagues. Pedro Pagés doesn’t have an obvious place in St. Louis and would be a more effective long-term caddy for Jonah Heim than current Texas backup Andrew Knizner, and the Rangers have a farm system that is lighter on starting pitchers than position players. I like Sem Robberse, but the Cardinals are full of no. 3 and 4 starters, and a healthy mid-rotation arm may simply be more valuable to the Rangers than to the Cards.

The New York Mets acquire RHP Carlos Estévez and LHP Reid Detmers from the Los Angeles Angels for RHP Blade Tidwell, SS/OF Luisangel Acuña, and OF Ryan Clifford

Carlos Estévez is one of the best relievers available at the deadline – and a pure rental – and if the Mets are interested in pushing for a wild card, as I believe they are, shoring up a weak bullpen is a good place to improve. I’m also a big fan of Reid Detmers. He’s commonly talked about as a “reclamation project,” but I think there’s good evidence to say that this year in the majors he pitched better than his surface-level stats showed. No competent major league pitcher is “truly” a .333 BABIP pitcher. Before being demoted, Detmers was having his best season yet in terms of missing bats, and I think he fits in the middle of the Mets rotation both immediately and over the next few years. Maybe I’m underrating the Angels as an organization, but I don’t think they would need a marquee prospect to make this trade, so I’m not going to throw one in willy-nilly. Blade Tidwell has struggled a little with command at Triple-A, but he ought to stick as a starter, and ZiPS is a pretty big fan of him long term. Luisangel Acuña is a tantalizing athlete who hasn’t really hit since he was traded to the Mets organization, and Ryan Clifford boasts plus power and has performed well at Double-A this year, but he strikes out a lot and doesn’t offer much defensively.

The San Diego Padres acquire LHP Yusei Kikuchi and RHP Yimi García from the Toronto Blue Jays for IF Eguy Rosario, C Brandon Valenzuela, and OF Homer Bush Jr.

With Yu Darvish out for personal reasons and Joe Musgrove’s exact timetable for a return still up in the air, the Padres could use an extra starting pitcher. Yusei Kikuchi is no ace, but he’s been solid the last two years and has pitched better than his raw ERA this season. He’s also a free agent at the end of the season, which makes him more movable for the Blue Jays than either Vladimir Guerrero Jr. or Bo Bichette, as I think 2025 is still very important to the Jays. The back of San Diego’s bullpen is also less than enthralling, and a Yimi García acquisition would give them more heft for the very wide open NL Wild Card race.

Naturally, neither Kikuchi nor García merit a top prospect in return, but they should at least get an interesting package. ZiPS actually likes Eguy Rosario quite a bit, projecting him for a 97 wRC+ in 2025 with +5 fielding runs at third, good enough to be a league-average player and help the Jays retool for next season. A healthy Manny Machado greatly reduces Rosario’s utility to the Padres. Danny Jansen is a free agent after the season and the Jays are short in prospects both behind the plate and in the outfield, and Brandon Valenzuela and Homer Bush Jr. are the types of 40ish prospects that frequently go in trades like this.

The New York Yankees acquire RHP Chad Green from the Toronto Blue Jays for IF Jared Serna

I’d be surprised if the Yankees weren’t after a late-inning arm, and they have a good history with Chad Green. I also think Green is unlikely to require a large price despite his solid ERA; his strikeout rate has fallen considerably and it’s backed largely by hitters making a lot more contact. Even before you consider Bichette’s free agency after next season, the Jays are in need of infield depth; I don’t think they see Addison Barger as a long-term middle infielder, but Jared Serna could fill that role.

Amusingly, Isiah Kiner-Falefa is having a strong season and would be useful for the Yankees at third base, but because the Jays need infield depth and might want to retool for 2025 rather than rebuild, they might choose to keep IKF, who is signed through next season.
