They say that the first step to fixing a problem is admitting that you have one. In that spirit, I’d like to start today’s article with a confession: I have a Trent Grisham evaluation problem. It feels good to say it! I’ve had this problem for years. Ever since he burst onto the scene in San Diego with two straight seasons of good hitting and great fielding, I’ve consistently overestimated his future trajectory. I put him on the first cut of my trade value list every year. I think of him as a starter even when the teams that employ him don’t.

I know all of this. When I’ve looked at Grisham in the past, I’ve seen an excellent player even when others haven’t, and I understand that this bias shades my evaluation. But just when I thought I was kicking the habit, Grisham goes and does something like this and pulls me right back in. Through Monday’s action, the first quarter of the season, he’s hitting a ludicrous .288/.373/.663, and while that’s not any reasonable hitter’s slugging percentage, he’s absolutely tattooing the ball, posting career high marks in barrel rate, hard-hit rate, xwOBACON, xSLG, average exit velocity… You get the idea, he’s just hitting everything very hard at the moment.

Now, as a reformed Grishamite, I have to tell you that hitting the ball hard isn’t one of Grisham’s shortcomings. Not quite like this, of course, because the only person who regularly hits like this is Aaron Judge, but he’s always been a threat to go deep. Grisham might have a low-ish wRC+ over the past three years, but the problem has been the quantity of his hits rather than the quality. Even while he scuffled mightily, he slugged roughly 20 homers per 600 plate appearances. He doesn’t always put the ball in play, but when he does, he makes it count.

Grisham also forces pitchers to come to him. He’s among the league’s best when it comes to chase rate, and he’s walking at a double digit clip. Again, though, I have to tell you that this isn’t new. Grisham’s chase rate is higher than it was last year, and his walk rate is below his career average. Unlike your typical outfielder with a below-average batting line, this isn’t an issue of Grisham never seeing a slider he doesn’t like. He’s quite willing to work a count if pitchers won’t challenge him in the zone. Read the rest of this entry »

If you’ve ever struck up a conversation with a stranger at the ballpark, you might have noticed that the FanGraphs readers are easy to spot. Let’s say you find yourself discussing the Yankees. A FanGraphs reader might ponder whether the 30-point gap between Paul Goldschmidt’s wOBA and xwOBA will catch up to him, while a non-reader is more likely to fret over whether Brian Cashman is too reliant on analytics when constructing the team’s roster. But sometimes, the two groups ask the same thing. So today, let’s consider one of those broad questions: Should teams be intentionally walking Aaron Judge more often?

Admit it. You’ve wondered. If you’re a Yankees fan, you’ve wondered just how long Judge is going to be allowed to hit in big spots. If you’re a fan of the team the Yankees are playing, you’ve wondered how your team’s manager ought to solve this impossible puzzle. And if you’re a neutral fan, well, Aaron Judge is the biggest story in baseball right now. He’s having one of the best offensive stretches in the history of the game. Don’t you want to know if there’s anything that can be done about it?

Ever since Barry Bonds broke the sport in the early 2000s, every hot streak in baseball comes with questions about the “Bonds treatment.” Now, that doesn’t necessarily mean 120 intentional walks, Bonds’ tally in 2004 and the single-season record. (It’s the single-season record by 52 walks. Second place? Barry Bonds. Third place? Barry Bonds.) The best non-Bonds total was Willie McCovey’s 45 in 1969. The most Judge has ever racked up in a single season is a measly 20. So the question isn’t whether teams should treat him like Bonds, because no, they shouldn’t. But should they treat him like McCovey? And more importantly, how should opposing managers handle Judge in a playoff game, when all the chips are on the table? Let’s do some math.

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. For once, I don’t have a fistful of double plays to show you. I don’t even have that many great catches. The baseball I watched this week was disjointed and messy, the regular season at its finest. Making the easy plays tough? We’ve got that. Bringing in your lefty to face their righty slugger? Got that too. Doubles that weren’t? Collisions between out-of-position players? Yes and yes. So thanks Zach Lowe for the wonderful article format, and let’s get started.

1. Tell ‘Em, Wash
I mean, how hard could first base be? Incredibly hard, of course. The Red Sox and Rangers are both on to their respective Plan Bs at first base after Triston Casas ruptured his patellar tendon and Jake Burger got sent down to Triple-A. No big deal defensively, right? Each team plugged in a utility player — Romy Gonzalez for Boston and Josh Smith for Texas — and moved on with life. Look how easy first is:

Jackson Chourio is a star. You can see it the second he steps to the plate. He looks like he’s always been in a batter’s box, like hitting comes as easily as breathing. He has easy power and shockingly good contact skills for someone who swings so hard. So, uh, why can’t he take a walk?

Fine, that’s hyperbole. It’s May 8, 38 games into the season, and he’s walked three times in 165 plate appearances. That works out to a 1.8% walk rate, the third lowest among qualified hitters. Jacob Wilson? He’s walked six times already. Michael Harris II? Four walks in fewer games. Name a guy you think can’t walk, with the exception of platoon players Kerry Carpenter and Michael Massey, and you can be sure that Chourio is walking meaningfully less than they are. Chourio didn’t walk a ton in 2024 – his 6.8% walk rate was in the 31st percentile – but this is something different entirely.

Naturally, when I started writing this piece before Tuesday’s game, Chourio had two walks in 161 plate appearances for the lowest walk rate in baseball, but then he walked his second time up in the Brewers’ 9-1 loss to the Astros. (For the rest of this article, I’ll be using stats as of the start of play on Tuesday.) Anyway, the point still stands: Chourio isn’t walking. What’s going on here? Read the rest of this entry »

Last week, I investigated the increasing divergence between the way pitchers approach same-handed and opposite-handed batters. I learned that pitchers across the league are varying their arsenals more and more every year. But that was a broad look, and I had some follow-up questions. Mainly, who specifically? Which teams? Which players? And how? Today, I’ll provide some answers.

As a refresher, I calculated what I’m calling “adaptation score” by comparing how frequently a pitcher uses his top-two offerings, both against same-handed and opposite-handed batters. Adaptation score is simply the difference between how frequently a pitcher throws his two best pitches when he has the platoon advantage and how often he throws those same two pitches when the batter has the edge. I split the data up by teams to see who was driving the move. First, we’ve got the five most and least adaptable teams in 2025:

Not much to see here. The Dodgers’ being on the bottom might suggest that adaptation is bad, even. But truthfully, there’s a big element we’re missing in looking at the data this way: personnel. Changing who’s on your team, even if you have the same philosophy, can change how you score in this metric. The Dodgers were in the middle of the pack last year when it came to adaptation score. Then they overhauled their pitching staff and ended up here.

It isn’t supposed to be this easy. When the Phillies traded for Jesús Luzardo over the winter, they did so with the understanding that he wouldn’t be an ace right from the jump. He was coming off a rough and injured 2024, he’d only hit 20 starts in a season once in his career, and every warning light you could possibly imagine was flashing – worst stuff model grades of his career, lowest strikeout rate, lowest whiff rate, highest hard-hit rate.

Those warning signs explain why the Phillies were able to acquire Luzardo for relative peanuts. It also explains why our projection systems were unenthused by him heading into this year, projecting a 4.19 ERA, a distant fifth among Philadelphia’s starters. No one doubts Luzardo’s potential, but after six seasons and 500 innings (itself not a great sign) of roughly league-average work, well, at some point you are what you are.

Right, yeah, Luzardo’s been the best pitcher on the Phillies this year and one of the best pitchers in baseball. I’m not as surprised as I thought I’d be. But given that we’re a quarter of the way through the season and his ERA and FIP are both below 2.00, I think it’s time to take a closer look at what he’s doing differently.

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. With the first month of major league baseball in the books, I’m settling into the rhythm of the regular season. Baseball writing in the morning, baseball on TV in the afternoon, and usually baseball on TV in the evening. Every so often, I’ll skip two of those and go to the ballpark instead. The actual baseball is falling into a rhythm, too. The Dodgers have the best record in baseball, Aaron Judge is the best hitter, and Paul Skenes is the best pitcher, just like we all expected. But part of the rhythm of baseball is that the unexpected happens multiple times a day, and that’s what Five Things is for. With a nod of recognition and thanks to Zach Lowe of The Ringer for the column format, let’s start the shenanigans.

1. Stopping at Third
The math is pretty easy: A double with runners on second and third scores both runners. Sometimes it even brings home a guy standing on first at the start of the play, too. Last week, though, things got weird. First, Jacob Stallings flat out demolished a ball off the right field wall, but Hunter Goodman didn’t have the read:

Hey, that happens. There are a few plays like this in the majors every year. The batter can tear around the bases as much as he wants, but runners have to stop and make sure it’s a hit first. Goodman couldn’t be sure that the ball would hit the wall, and with no one out, he quite reasonably played it safe. Blake Dunn played the carom perfectly, and again, with nobody out, Goodman didn’t try his luck at home. Read the rest of this entry »

Every winter, pitchers step off the mound and into the lab. Sure, not every pitcher is in a wind tunnel with a high speed camera from October to January, but enough are that everyone seems to reap the benefits. You’ve got the sweeper, the kick change, the rise of the splitter, new fastball shapes – you name it, someone has tried it recently. That means that every year, I spend the first month or two of the season catching up to the new hot thing going on in the world of pitching.

But I have to level with you: On the whole, things haven’t changed as much this year as I expected. That won’t stop me from walking through what has changed, though, and the first shift to highlight is a subtle one – we’re seeing more bendy sliders and fewer gyro offerings:

Why? Two things are happening. First, sweeping sliders do better against same-handed batters, so pitchers are choosing that as their secondary of choice when they have the platoon advantage. In 2021, 2.6% of pitches that righties threw to righties were sweepers. In 2025, that number has ballooned to 10.7%; it’s 10.9% for lefties against lefties. Usage is less than half as high when opposite-handed batters are at the plate.

Meanwhile, “regular” sliders are on the decline when pitchers have the platoon advantage. That makes good sense – they’re just throwing sweepers instead. And when pitchers aren’t facing same-handed batters, neither slider is particularly great; pitchers are staying away from both, more or less. That means that the traditional, gyro-spin slider is declining in prevalence overall. Read the rest of this entry »
