This season is the third since the implementation of a spate of significant rule changes across the majors. Along with a pitch clock and limits on defensive positioning, a limit on disengagements (read: pickoff throws plus idle standing around) combined with slightly larger bases gave runners a collective green light. With fewer throws to first, bigger targets to slide into, and more predictable pitcher deliveries thanks to the clock, stealing a base got much easier overnight. In 2022, the last year of the old rules, the majors saw 2,486 steals across the entire season. In 2024, that number surged to 3,617 steals. Even better from an offensive perspective, the stolen base success rate jumped from 75.4% to 79% over that span.

The first year of the new rules was all about experimentation. Some players ran wild – Ronald Acuña Jr. more or less took off every time he could. Meanwhile, the Giants stole just 57 bases as a team, fewer thefts than the previous year, when those steal-boosting rules weren’t yet in effect. None of that seems particularly surprising to me; when new rules of this import are added to the game, every team will scramble to figure out how to change their own behavior to benefit. There were a ton of moving parts, and many teams took a simple approach: keep stealing more and more until it starts to fail.

The 2024 season was the year of the defensive reaction. Teams attempted 209 more steals in 2024 than they did in 2023, but only succeeded on 114 of those extra steals. The aggregate effect was a lower success rate on marginally more attempts. Catcher pop times improved, pitchers threw over more often, and defenses were more attentive to baserunners in general. That brings us to 2025, and in the early going, it looks like the baserunners are continuing to push the envelope:

Hello there, FanGraphs readers. Today I’d like to tell you about a reliever on the Los Angeles Angels. Now sure, just last week, I wrote about how much help the Angels needed on the pitching front, and in the bullpen in particular. And sure, the guy we’ll be discussing today has a 4.05 ERA and a 4.08 FIP so far this year, not exactly stud closer numbers. Was he a trade throw-in last summer, one of four lottery tickets the Angels landed in exchange for a reliever in a contract year? He sure was. But that doesn’t change the fact that he’s interesting. So I’d like to introduce you to Ryan Zeferjahn, the best reliever you’ve probably never heard of.

The first thing you should know about Zeferjahn is that his primary pitch is weird. Everyone calls it a cutter, and in many ways, that makes sense. Let me show it to you in action:

Yep, that’s a cutter. It’s 90-ish mph, with less rise and arm-side fade than a four-seam fastball, and it makes batters look uncomfortable because they can’t quite classify whether it’s a fastball or a breaking ball. Miguel Vargas read that pitch as inside, and then it held the plate thanks to unexpected cut. But Zeferjahn’s cutter has, for lack of a better way of saying it, a lot of cut even for a cutter. This isn’t something you would pick up from watching a GIF or two, but that pitch has about six inches of glove-side break. Read the rest of this entry »

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. There must have been something in the water across the league over the past seven days, because while this column always highlights delightful oddities that I caught, they aren’t often so delightful or so odd. This week, rarities abounded. There were runners getting hit by throws, wild acrobatics, no-look passes, and even a pitchout. Hot teams and cold teams clashed, errors got compounded, and situations that felt in hand rapidly got away. So keep an eye on the runner at first base, and let’s get started – after my customary thanks to Zach Lowe of The Ringer, who popularized this column format for basketball.

1. Not-Quite-Free Bases
Jarren Duran is off to a slow start to the 2025 season. And while the problems have mostly come at the plate, everything seems a little off. Take this misadventure on the basepaths last Thursday. Duran led off the bottom of the 10th inning with a game-tying single. That made him the winning run, and he immediately started plotting a theft of second base to get into scoring position. Nick Sandlin checked on him:

Then he checked on him again:

That’s two disengagements; Sandlin wasn’t likely to try again. Duran stole 34 bases last year. He’s blazing fast. He was 5-for-5 on the season and had already swiped one in this game. Second base was as good as his. And so the Blue Jays took extreme measures, calling for one of the least-used plays in modern baseball, a pitchout:

It’s never fun being the subject of a story that people call a saga. So when the Pete Alonso free agency saga transpired over the winter, I wondered whether he’d get off to a sluggish start as a result. Signing for less money than your agent told you you’d make, later than you expected to sign, and with a team offering you a smaller contract than they had the year before? It’s enough to make spring training a bit less of a ramp-up period and a bit more of a time for taking out frustration. If Alonso had started slow this season, I wouldn’t have raised an eyebrow.

Turns out, Pete Alonso isn’t like me. Instead of sulking a little and coasting into the regular season, he’s come out like a man possessed. Through Tuesday’s action (17 games), he’s hitting an outrageous .356/.466/.729, the kind of batting line that doesn’t really make any sense and doesn’t need to. Suffice it to say, he’s not going to stay this hot unless he’s secretly Lou Gehrig, a development that would raise more questions than it answered. So we don’t need to ask whether this form is real – we can instead focus on what Alonso is doing the same and differently, and then go from there.

What is Alonso best at? That’s right, hitting the ball in the air with authority. That’s always been his calling card and it’s no different this year. Want a simple way of stating that? He leads the majors with 13 barrels, one ahead of Aaron Judge. That’s the kind of power you’d expect from a first baseman who averages 38 homers per 600 plate appearances (2020 makes “per year” stats pretty annoying). Even last season, Alonso’s worst in the bigs, he finished 13th in the majors in barrels. He plays a lot and he hits the ball very hard; those are things we’ve always known about Alonso.

Have you seen all the technological advances taking over pitching in recent years? High-speed cameras, pitching labs, weighted ball training, wind tunnels – maybe the reason we haven’t sent anyone to the moon for decades is that we’re using all the technology to strike batters out instead. Clearly, the arms race (get it?) favors technological savvy and complicated, inscrutable mathematical modeling.

Here’s a counterpoint, though: Maybe you should just throw a fastball and a slider and laugh as batters flail at both. Case in point: Randy Rodríguez has been the best reliever in baseball this year, and there’s nothing fancy about his game. He throws a 98-mph fastball. He throws a tight slider. That’s it – and that’s really all he needs anyway. Through eight appearances this year, he has 13 strikeouts, zero walks, and zero runs allowed.

Oh, two paragraphs don’t make an article? Well then, I guess we should expand on everything a bit. First, his backstory: Rodríguez signed with the Giants in 2017 out of the Dominican Republic and then slowly climbed the minor league ranks. He was a reliever right from the jump, with only occasional dalliances with short-burst starts, and he got a taste of Triple-A in 2022, where he got shelled. He tried it again in 2023 with better results, and by 2024 he looked like he belonged. That was his first year in the upper minors with a single-digit walk rate, and that’s all the Giants were waiting for; they called him up midseason and plugged him into the bullpen.

For the past half decade, Logan Webb has been one of the game’s premier starters. He churns out 30-start seasons with ERAs in the 3s like clockwork; that’s almost exactly his seasonal average since switching to a full-time sinkerballer in 2021. In that span, he’s averaging 4.4 WAR per year, and he’s topped 200 innings in each of the past two seasons. This year, he’s atop the leaderboards again, with a 2.63 ERA and 2.25 FIP through four starts. But there’s something new to see here, and it’s a change I thought Webb would make for years before he actually did, so I think an updated look is in order.

Webb’s approach was simple and yet effective. He threw three pitches to righties: sinker, sweeper, changeup. Against lefties, he threw fewer sweepers and more changeups, and he also mixed in a few four-seamers in lieu of sinkers. For the most part, though, he alternated his three best pitches, weighted to suit the batter he was facing. Here’s a great graphic, courtesy of Baseball Savant’s player pages, that shows Webb’s movement profile. I picked 2023 for reasons that will become obvious shortly:

This shows a few things about Webb’s game in one image. His sinker and changeup move very differently from the league-average versions of those pitches. His four-seamer, rarely thrown, is effective not because of inherent shape, but because it’s different from his primary fastball. His sweeper is the only thing he throws that breaks glove side, and it breaks that way by quite a lot. If you’re facing Webb, you’re either going to see something that tails hard arm side (sinker or changeup) or something that shoots hard glove side (sweeper). It’s like facing Clay Holmes or Blake Treinen for 100 pitches at a time. Read the rest of this entry »

This spring, the Angels banned the use of cell phones in their clubhouse. I read that news with great interest, since like so many people these days, I have a love/hate relationship with the little screen in my pocket. I really do feel like looking at it less often could help me out. What better laboratory to test the wholesome effects of less screen time than a high stakes sport?

Then I thought a bit more about the situation and laughed. Could cell phone usage bring the Angels to the playoffs? Signing Shohei Ohtani for a pittance couldn’t bring the Angels to the playoffs. Drafting Mike Trout, one of the greatest players in the 21st century, and then twice signing him to contract extensions has only taken the team to October once in Trout’s career. Maybe this was the wrong team to pin my hopes to. But fast forward three weeks, and who sits atop the AL West but the Los Angeles Angels, in the first year where they banned cell phones. Coincidence?

I mean, yeah. Thanks for bearing with me for that extended introduction, but this isn’t an article about the evils of technology. Instead, it’s about what’s gone right in Anaheim so far this year, and whether that should change our view of the team going forward. Read the rest of this entry »

Welcome to another edition of Five Things I Liked (Or Didn’t Like) In Baseball This Week. I was at a wedding this past weekend, a generally fun event for a baseball writer. That’s because strangers ask me what I do, and then I get to say, “I’m a baseball writer.” That plays a lot better than, “I work in accounting/finance/tech,” no offense to any of you in those fine fields. But this weekend, someone inquired deeper. “Oh, like sabermetric stuff?” “Yeah! Kind of. Also I make GIFs of dumb and/or weird plays. And bunts, lots of bunts.” Yes, it’s a strange job being a baseball writer, but also a delightful one, and this week delivered whimsy and awe in equal amounts. So unlike guests milling around at a wedding, let’s get straight to the point – after the customary nod to Zach Lowe of The Ringer for the inspiration for this article format.

1. Not Reaching Home
The third time a runner was tagged out at the plate in Wednesday’s Cardinals-Pirates clash came at a pivotal moment. Locked in a scoreless tie in the bottom of the 11th, Pittsburgh finally looked like it would break through when Joey Bart singled to right. But, well:

That was a good throw by Lars Nootbaar and a clean catch by Pedro Pagés, and that combination turned a close play into a gimme. I mean, how often are you going to be safe when the catcher already has the ball in his glove and you’re here:
