Hello, all of you FanGraphs readers! Are you a FanGraphs Member? Are you looking for something fresh to read on Saturday mornings? Do you have any burning baseball questions for us, but don’t quite know where to ask them? Well, then we’ve got great news for you.

FanGraphs is launching a weekly mailbag, curated by me, that will run on the website every Saturday morning. Anyone can submit a question, but the piece answering them will only be available to FanGraphs Members.

So how is this going to work? Send any and all of your questions — about baseball, baseball writing, or whatever else you might be interested in having us answer — to me via email at mailbag@fangraphs.com, and each week, I’ll pick a few that we’ll answer in that Saturday’s mailbag. That’s right, I said we, because my FanGraphs colleagues will be helping me out. If you have a Hall of Fame question, I’ll probably relay it to Jay Jaffe. We’ve got Eric Longenhagen for prospect inquiries, and Dan Szymborski if we need to consult the ol’ ZiPS machine — the list goes on! We’ll do our best to answer as many questions as possible each week, but we won’t be able to get to them all. The ideal mailbag question is something that requires a deeper dive than we can tackle in our various chats, but is not so expansive that it warrants an entire article. Read the rest of this entry »

Mikey Romero has hit a few speed bumps since the Boston Red Sox drafted him 24th overall in 2022 out of California’s Orange Lutheran High School. A back injury limited the 21-year-old multi-position infielder to just 34 games in 2023, and he then didn’t return to game action until last May. He also missed time in August after suffering a concussion.

When healthy, it’s been mostly smooth sailing for the former first-rounder. [Boston took Roman Anthony 16 picks later the same year]. Romero’s last-season ledger included 16 home runs and a 125 wRC+ over 362 plate appearances between High-A Greenville and Double-A Portland.

He’s off to a strong start in the current campaign. Back at the higher of those levels, Romero is swinging to the tune of a 134 wRC+ in 154 trips to the plate. Fully half of his 34 hits have gone for extra bases. The San Diego native’s smooth left-handed stroke has produced 10 doubles, a pair of triples, and five home runs.

As the season was getting underway, I asked the promising youngster how he’s grown as a hitter since joining the professional ranks. Read the rest of this entry »

Ben Lindbergh and Meg Rowley banter about the most exciting prospects who haven’t yet made the majors but should soon (including Jac Caglianone, Roman Anthony, Bubba Chandler, and Andrew Painter), the struggles of once-ballyhooed trade targets Sandy Alcantara and Luis Robert Jr., the recent rebounds of Emmanuel Clase and Devin Williams, the returns of Mike Trout, Ronald Acuña Jr., and Spencer Strider, the differing trajectories of former Reds relievers Fernando Cruz and Alexis Díaz, the surprisingly successful and homegrown Yankees, the looming specter of Craig Kimbrel, watching Paul Skenes, what baseball would be like with man defense, not zone, and teams whose playoff odds have increased or decreased the most in the season’s first two months.

With the sixth pick in the 2024 draft, the Kansas City Royals took slugger-pitcher Jac Caglianone out of the University of Florida, and set him to the task of being a full-time hitter. Caglianone’s short 2024 debut was a middling performance at best, as he hit .241/.302/.388 for the High-A Quad Cities Rivers Bandits, and while he showed impressive power in spots in the Arizona Fall League, he hardly dominated the opposition.

But since the calendar flipped to 2025, Caglianone has been on a quest for vengeance against pitchers with the ferocity of a Liam Neeson movie protagonist. First, he went 9-for-18 in spring training with six extra-base hits, in order to give major leaguers fair warning that he was coming for them. After hitting .322/.394/.553 for Double-A Northwest Arkansas, a promotion to Triple-A hasn’t tamped down his homerlust, and he’s already smacked five home runs for Omaha. The question of Caglianone’s promotion to the majors has rapidly become “when” rather than “if,” and it’s in the interest of the Royals to answer it with a three-letter word: “Now.” Read the rest of this entry »

If Tarik Skubal locates his fastball up in the zone, opposing hitters are probably cooked. Nearly half the time they swing, they come up empty. If they manage to put it in play, they’re unlikely to do much damage — of the six hits he’s allowed on elevated heaters, five have been singles. That lone extra-base hit? An absolute tank! A 429-foot home run, off a perfectly executed 98-mph heater on the first pitch of the game, courtesy of one Zach Neto, who is currently making a case for low-level stardom.

After a rough rookie campaign in 2023, Neto broke out in his sophomore effort, posting 3.5 WAR by playing a competent shortshop and clubbing enough home runs (23) to cover up his mediocre on-base ability. Even after missing the first few weeks of this season with a bum shoulder, the 24-year-old has managed to take another step forward in 2025: His 139 wRC+ ranks second among all shortstops with at least 150 plate appearances.

That improved line is fueled by a power surge. In just 37 games, he’s homered nine times and hit 10 doubles. The barrel rate has literally doubled, jumping from an 8.4% rate last year to 16.8%. As a result, his .589 expected slugging (xSLG) ranks eighth in baseball, just below big-time sluggers like Aaron Judge, Shohei Ohtani, and Kyle Schwarber.

Those three guys are hard swingers, perennially topping the bat speed leaderboards. But Neto doesn’t fit that profile. He stands at a slender 5-foot-11; even with a slight uptick in bat speed year-over-year, his 71.7-mph average swing speed falls below the big league average. The Angels shortstop isn’t posting elite power numbers because he’s swinging the bat hard. It’s because he’s maxing out the aggression in his approach, selling out for power and mostly succeeding.

A couple of weeks ago, Hannah Keyser of The Bandwagon asked Kodai Senga about his reverse splits when it comes to times through the order. His .347 wOBA allowed the first time through the lineup drops to .275 the second time through it, and then sinks to .205 the third time through. However, his total batters faced sits at just 90 for each of the first two times through the order and 48 for the third time through. That’s a small enough sample that it’s difficult to say how much of the credit goes to Senga and how much is naturally occurring variation.

Either way it doesn’t matter much to Senga, who cares more about process than results, “Quite honestly, I don’t feel like I’m very good at any point during the game this year,” he told Keyser through his interpreter. Harsh words for a pitcher with an ERA- of 37. He does acknowledge that he makes adjustments throughout the game to get a better feel for his pitches and tweaks his strategy based on how each pitch is looking in a given start, which offers some explanation for the improved outcomes as the game goes on. But according to Senga, all of his pitches feel off this year, as he remains in the process of re-establishing his mechanics following the shoulder and calf injuries that sidelined him for nearly all of last year.

Senga’s self-evaluation reminds us that folks performing at the elite level of their fields don’t get there by letting good enough be good enough, but rather by insisting that nothing is ever good enough. To the layperson, it’s baffling to hear that Senga feels he’s pitching worse, despite posting better results than in 2023, his first MLB season, and the last in which he was fully healthy. Add on that he somehow manages to gain effectiveness throughout his starts despite a certain level of displeasure with all of his pitches, and it couldn’t be any clearer that regardless of what you read in Us Weekly, the stars are not actually just like us.

Hello, and welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. Memorial Day marks the point at which we’re a third of the way through the season, a great time to take stock of how preseason story lines have fared in the light of the regular season day. The Orioles might be bad. The Phillies and Tigers might be great. The Rockies might be the worst team of all time. Aaron Judge might be an alien. We’ve learned a lot so far – but none of those things affect the day-to-day experience of watching baseball. That’s what I like about it so much – you can turn on a random game, completely ignore any of those overarching narratives, and still see something delightful. So this week, let’s celebrate the little things that don’t necessarily win games but do consistently bring a smile to my face. With my customary nod to Zach Lowe of The Ringer for his basketball column that inspired this one, let’s dive in.

1. Determination
I’ve always been fascinated by Nick Allen, who blends elite shortstop defense with a completely powerless approach to offense. That combination got him traded to the Braves this winter to play a utility infielder role, but he outplayed Orlando Arcia in spring training to claim the starting job, and he’s been running with it. Not on offense – his 68 wRC+ is both mortifying and a career high – but on defense, he’s never been better.

Allen’s defense is many things, but most importantly to me, it’s kinetic. He doesn’t give up on plays. He’s always moving. He’ll throw from any platform, any arm angle, jump or twist or slide to get more force behind it. He’s graceful around second base, but it’s a nervous kind of grace, a ballet dancer after four shots of espresso. And if something gets in his way, he’ll just run through it:
