I humbly request that you watch the following home run three times. During your initial pass, I merely ask that you permit yourself to marvel at the power of Pete Alonso. Exclaim, should you feel so moved. This level of ferocity certainly merits stiffer punctuation than a period can provide.

The second time you take it in, allow yourself to focus on the reactions. Catcher Dalton Rushing and baserunner Brandon Nimmo offer an illuminating interplay. Nimmo cranes his head toward the heavens and prepares to tag up on the play in spite of the fact that the ball goes on to land some 900 feet past the left field wall. Rushing recognizes at once that the ball has attained escape velocity, and he reacts by lifting his hands with enough suddenness and precision to send you searching the web for the phrase “rude Italian hand gestures.” A couple behind the plate provides a master class in the Long O sound:

SHE: Whoa.
HE: [EXPLETIVE DELETED] Nooo.
SHE: Ohhhh!

On your third pass, please focus exclusively on pitcher Ryan Loutos as he crumbles into dust. The young pitcher’s delivery is a study in contrasts. He’s all elbows and knees as he drops and drives, but he finishes with such rotational force that his follow-through twists him all the way around toward first base, torso first, arms and right leg swinging forward in neat arcs to catch up. He’s linear then rotational, angled then curved, herky-jerky then smooth. Read the rest of this entry »

It’s not the results. I mean, it’s not not the results. Nobody feels good about an 0-4 record or a 5.68 ERA. But while the top line numbers are reason enough to worry about Spencer Strider, changes to his delivery and pitch shapes point to deeper concerns. The 26-year-old right-hander has made just four starts this season, but it’s reasonable to ask whether he’ll ever regain the form that just two years ago made him one of the most dominant forces in the game.

First and foremost, this stinks. Strider is a charismatic young player who’s easy to root for. When he’s at his best, standing bow-legged on the mound with his muscles threatening to shred his uniform pants, blowing 100-mph heat past anyone unlucky enough to find themselves in the batter’s box, he’s appointment viewing. After a cup of coffee in 2021, Strider burst onto the scene a fully-formed ace in 2022, laying waste to the league with a 98-mph fastball, a wicked slider, and a rumor of a changeup. From 2022 to 2023, his 2.43 FIP was the best among all starters, and his 10.3 WAR trailed only Kevin Gausman’s 10.7. Strider’s 3.36 ERA was 16th-best among starters with at least 300 innings pitched, and he looked for all the world like he would spend the rest of the decade as a true ace. Four games back from the internal brace surgery that wiped out nearly all of his 2024 season, we’re forced to reassess. Read the rest of this entry »

When I wrote a few weeks ago about how Kyle Schwarber deserves to be the first player in baseball history to get not his own bobblehead doll, but rather his own bobble helmet doll, I neglected to mention one thing. Schwarber has been brilliant this season. He’s off to the best start of his entire career. Schwarber is currently running a 164 wRC+, which makes him the eighth-best qualified hitter in baseball. His 19 home runs and 16% walk rate both rank in the top five. That excellent spring is all the more impressive considering that Schwarber is, relatively speaking, something of a slow starter. He owns a career 110 wRC+ in March and April, followed by a 115 mark in May, then a 145 mark in June. This season, he just started out hot and got even hotter. Here’s a table that shows his wOBA in March and April through his entire career:

Schwarber has had plenty of hot streaks like this one before, but never to lead off a season. Moreover, the way he’s doing it is different. With Joey Gallo attempting to reinvent himself as a pitcher, Schwarber stands alone as the game’s foremost practitioner of the Three True Outcomes, but he’s doing his best to abandon one of those outcomes. He’s currently running a 24.4% strikeout rate, which would represent the lowest rate of his career and a drop of more than four percentage points compared to last season. In addition to lowering his strikeout rate, Schwarber is doing more damage than ever when he puts the ball in play. His .499 wOBAcon and .531 xwOBAcon are the best marks of his entire career.

Yesterday, Hannah Keyser, of the excellent Bandwagon newsletter, threw down the gauntlet on Bluesky. She posted a screenshot from MLB Network’s daily research packet and wrote, “I challenge the researches at MLBN who put out the daily stat packet to find a split that makes the Rockies look good.” The screenshot featured a single line of text:

The daily research packet is exactly what it sounds like, a multi-page document that contains tons of research on the day’s slate of games, broken down into bit-sized pieces of interesting information. A team of researchers assembles it each morning, then distributes it far and wide across the baseball media ecosphere. Although you’ve probably never seen this document, it has unquestionably informed your experience as a fan. Each broadcast team has its own researchers, of course, but if you’re watching a game and you hear the announcer casually mention that Mickey Moniak is batting .333 with a .476 slugging percentage when he represents the go-ahead run, you can feel pretty confident that they read that fun fact verbatim from the packet.

Just over a year ago, the Brewers made the best kind of baseball history: weird baseball history. On May 31, 2024, they hosted the White Sox in Milwaukee, shellacking them 12-5. That part wasn’t weird. It’s hard to imagine anything less weird than the 2024 White Sox losing a baseball game (unless it’s the 2025 Rockies losing a baseball game). The weird part was how the Brewers beat the White Sox. They put up 23 hits, and 16 of those hits came on groundballs. That’s the most groundball base hits ever recorded since the pitch tracking era began in 2008. Would you like to see them all? Of course you would.

That’s what a record looks like. Groundball after groundball finding the various nooks and crannies that made the 2024 White Sox defense so similar to an English muffin. We’ve been waiting until this game’s anniversary to write about it. According to Baseball Savant, since 2008, only one other team has surpassed 12 groundball base hits in a single game. The White Sox tallied 15 against the Tigers on September 14, 2017. And that’s it. That’s the only team that came within three groundball hits of Milwaukee. First, let’s talk about how the Brewers pulled off this feat of worm-burning ingenuity.

As with any record, a fair bit of luck was involved. Balls took crazy hops off the mound and the first base bag. The Brewers hit a perfectly placed chopper and sent a ball hugging the third base line on a check swing. They wouldn’t have broken the record if any one of those balls had bounced another way. But as the saying goes, luck is the residue of design, and there was plenty of design involved here too. Read the rest of this entry »

This year, Josh Bell returned to Washington with a new goal in mind. “What this team needs is slug,” he told reporters during a Zoom call when he signed back in January. He explained that although he’d always prided himself on making contact and avoiding strikeouts – Bell’s career strikeout rate is 14% below the league average and his slugging percentage is 5% above it – he was finally ready to make use of his 6’3” frame and trade contact for power:

That’s kind of in my DNA, but understanding MVPs the last few years, they hit 40-plus homers and they might strike out 150-plus times, but that doesn’t get talked about. The slug is the most important thing. That’s where WAR is. That’s what wins games… I have a big frame, and I should probably hit more than 19 home runs a season. Hopefully, a year from now I can be looking back on a season where I had 40-plus and break my own records for slug in a season. That’s the goal.

Bell came into the season with a more upright stance, a slightly higher leg kick, and a new mission. “I feel like I’m not afraid to strikeout more if it means less groundballs,” he said in February. “I know when I’m at my best, I don’t hit the ball on the ground. I strike out a little bit more. So if I can take one and get rid of the other, then I’ll be in a good place and the average should stay the same or go up. Time will tell.”

I bring all this up because Bell has seen a huge change in his batted balls this season, but it’s very definitely not the change he hoped to see. So far this season, he’s running a .173 ISO, a bit down from his career mark, but more or less in line with what he’s done for the last several years. His hard-hit rate and exit velocity are nearly identical to last season’s marks. So in terms of both results and raw contact quality, he’s not more powerful, but he’s not less powerful either. The experiment may have failed, but it didn’t blow up the laboratory. Read the rest of this entry »

You can’t keep Pete Crow-Armstrong away from the baseball field. I mean that in the sense that he’s a passionate young star who loves the game and plays with his hair on fire all the time. But I also mean that in a more literal sense. The Cubs might need to devise a system for keeping Crow-Armstrong away from the baseball field. He has a problem.

The Cubs walked off the Rockies on Monday night. The score was 3-3. With one out and two on in the bottom of the 11th inning, rookie Matt Shaw stayed back and punched a Tyler Kinley slider into right field, scoring Jon Berti from second base. It was thrilling. (For the Cubs, anyway; for the Rockies, it was probably akin to the feeling you have when you go to bed with a tickle in your throat and you just know that it’s a really bad cold coming on even though there’s no tangible basis for that certainty, and then you do in fact wake up in the middle of the night with a terrible cold.) As you’d expect after a thrilling(-slash-miserable) walk-off hit, Shaw got mobbed by his teammates.

Well, he got mobbed by one teammate, anyway. There’s Shaw, moments after his big hit, engaged in an intimate leaping chest bump with Crow-Armstrong. I mean “intimate” in the sense that it seemed like a special moment, but I also mean it in the sense that it’s just the two of them all alone on the grass under the romantic Chicago skies, smiling at each other like there’s nobody else in the whole wide world. The rest of the Cubs are just out of frame, celebrating too. Read the rest of this entry »

This is not the company the Red Sox hoped they’d be keeping. When they face off against the Brewers tonight, they’ll be trying to avoid joining the Rockies, White Sox, Pirates, and Rays as the only teams in baseball with three separate losing streaks of at least four games this season. Boston currently sits fourth in the AL East and 2 1/2 games out of the final Wild Card spot. According to our playoff odds, the Red Sox have seen their postseason probability fall by more than half since Opening Day, dropping from 56.2% to 25.3%. Only the Braves, Orioles, and Rangers have had a bigger decline.

Boston’s most recent win also provided its biggest loss of the season thus far. When Alex Bregman signed back in February, there was every reason to believe that the Green Monster would be his best friend. His game is designed around lifting the ball to the pull side, and he’s already bounced five doubles and a single off the wall on the fly, to go with three homers launched over it. But the Monster betrayed Bregman on Friday. In the first game of a would-be doubleheader against the Orioles (the second game was postponed, and Saturday became a doubleheader instead), Bregman scorched a single that short-hopped the wall, but as he chopped his steps to back off an aggressive turn, something looked off.

“I was rounding first base and digging to go to second and I kind of felt my quad grab, so I didn’t continue running to second base for the double,” Bregman said. “I just kind of stopped and came back to the bag so I wouldn’t make it any worse. After I felt it, I knew I needed to come out and see the trainer.” Bregman left the game with right quad tightness, telling reporters that he initially feared that the injury might be more severe, but that he felt more positive after the game and hoped he could avoid an IL trip. “Hopefully, I sleep good and it feels great,” he said. “We’ll just see how it presents and take the next step there, just kind of follow the training staff, their lead. But right now, it’s just quad tightness.”

Bregman didn’t sleep good. Pain from the quad kept him up during the night, and an MRI on Saturday morning revealed a “pretty severe” strain. Bregman compared it to the left quad strain he suffered in 2021. That strain kept him out 69 days, from June 17 to April 25. In case the Red Sox are looking for consolation, Bregman looked like himself upon his return that season, running 115 wRC+ before the injury and a 112 wRC+ (with better exit velocity numbers) after he came back. But that’s cold comfort. With a 160 wRC+ this season, Bregman has been the team’s best player, and he’ll be out for at least two months. Read the rest of this entry »

He doesn’t look like he’s riding a horse so much as he looks like he’s pretending to ride a horse. I have been thinking about it for a while now, and that is as well as I can describe the way Jacob Wilson gets ready for the pitch. He looks like he’s pretending to ride a horse. I say this with love.

Baseball is hard. The ball is small and very dense. A big, strong man stands not very far away and repeatedly throws it pretty much right at you with a great deal of force. The ball performs all sorts of twists and turns on its short journey toward almost breaking your fragile human body, and not only are you expected to not run away, you’re expected to hit it with a stick. So if the only way that you can manage to do all that is by pretending to ride a horse for a few seconds while you’re waiting for the missile to be launched, then by all means, pretend to ride a horse for a few seconds:

(I started writing this article the day after the Statcast team released all their new fancy bat tracking information, including wireframe models of every player’s average swing. Naturally, I offered MLB.com’s Mike Petriello $20 to find me a few seconds of wireframe footage of Wilson doing his bouncy pre-pitch routine. He declined like a principled jerk, even after I upped the offer to $23.) Read the rest of this entry »

Yesterday, I wrote an introduction to Statcast’s latest round of bat tracking metrics. MLB.com’s Mike Petriello wrote a real primer, so I tried to build on that by analyzing how the different metrics work together using a couple common pitch types. We’re still figuring out how to use these new toys, but today I’d like to explain how my first dive into the bat tracking metrics led me to one particular player who is doing something weird, which led me to learn something small about the way swings work. After all, that’s why we’re here exploring all these strange new numbers in the first place.

In my first shot at playing with the metrics, I tried to establish something simple. I pulled the overall bat tracking data for all qualified players, and I focused on Attack Direction, which tells you the horizontal angle of the bat at the moment of contact (or, in the case of a whiff, at the moment when the bat is closest to the ball). That seemed pretty straightforward to me. As with most bat tracking metrics, it’s also a timing and location metric. You generally need to meet inside pitches further out in front of home plate. If you’re behind the pitch, your bat will be angled toward the opposite field, and you won’t pull the ball. If you’re out in front of the pitch, your bat will be angled toward the pull side, and you’ll pull it. A player’s average Attack Direction should correlate pretty well with their pull rate, and the numbers pretty much bear that out. Attack Direction and pull rate have a .60 correlation coefficient:

Most of the dots are clustered around that very clear trendline. Players who pull the ball more tend to have their bats angled toward the pull side just as you’d expect. What interested me was that green dot way at the bottom. It belongs to Leody Taveras. I guess it is Leody Taveras, if we really believe in our graphs, which we probably should at this particular website.

Taveras has a moderately low Attack Direction, four degrees to the pull side, but he’s got the third-lowest pull rate of any player on this chart. I couldn’t help wondering how exactly he was doing that. Before I dug into it too deeply, I was reminded that the fact that he’s a switch-hitter might have something to do with it. So I pulled the data again, this time separating out all players by handedness. On the chart below, switch-hitters will appear twice:

The correlation isn’t quite as strong, because switch-hitters are now broken into two different players with two smaller samples (that’s how small-sample right-handed Patrick Bailey got way down at the bottom). But there are two green dots now! And they’re both Leody Taveras! From both sides of the plate, Taveras looks like he should have a pull rate that’s a bit above average, and instead has one of the very lowest pull rates in the game. At this point, I was officially curious, so I started poking around.

First, I specifically looked at Attack Direction on balls hit to the opposite field. Since the start of bat tracking midway through the 2023 season, when Taveras hits the ball the other way, his average Attack Direction is three degrees toward the opposite field. Only four players in baseball have an average Attack Direction that’s less oriented toward the opposite field. Oddly, they’re all sluggers. Salvador Perez, Yordan Alvarez, Aaron Judge, and José Ramírez are all at two degrees toward the opposite field, and Austin Riley is tied with Taveras at three degrees. Taveras is definitely not a slugger. He could not be more different from these five guys. So not only is he doing something way different from most hitters when he goes the opposite way, but the only players out on that ledge with him have completely different swings than he does. There really is something weird about him.

Next, I tried looking specifically for balls hit to the opposite field even though the bat was angled toward the pull side at the moment. Just 21% of balls hit to the opposite field have the bat angled toward the pull side at all. I ran a Baseball Savant search, setting the minimum Attack Direction at seven degrees toward the pull side. Since bat tracking started, 5.5% of Taveras’s batted balls have fallen into this category. Among the 375 players with at least 200 BIP over that period, that’s the 11th-highest rate. Elehuris Montero is the champion at a shocking 10.5%, but no player who has put as many balls in play as Taveras has run as high a rate as he has.

At that point, I decided to look at individual balls that fell into this category: balls that go to the opposite field even though the bat is angled toward the pull side at contact. How exactly does this happen? Try to picture it in your mind. If the bat is angled toward the pull side, and it’s being swung in that direction anyway, how does the ball end up going in the opposite direction? There are two main answers. Here’s the less common way:

That’s Taveras way, way out in front of a curveball, hitting it off the very end of his bat. He cued it up so perfectly that if the end of his bat were cupped, the ball might have just gotten stuck in there. So that’s one way to do it. In fact, 21% of the balls we’re looking at, hit to the opposite field even though the Attack Direction is seven or more degrees to the pull side, are squibbers hit off the end of the bat below 80 mph. That’s one way to do it.

The other way is much more common, and it looks like this:

Of those same balls, hit to the opposite field even though the Attack Direction is seven or more degrees to the pull side, 50% are classified as popups, and 65% have a launch angle above 38 degrees. Basically, when you hit a ball in that weird manner, it’s almost always going to be either a cue shot or a popup. Leody Taveras taught me that.

This has a lot to do with Attack Angle. If your bat were perfectly parallel to the ground, but angled toward the pull side, it would be pretty much impossible to hit the ball the other way. But when you pop the ball up, you’re not hitting it flush. You’re getting under it. And regardless of the situation, your bat is almost never parallel to the ground. According to Statcast, the bat is angled downward on more than 80% of swings. If you just look at popups, that number is up above 90%. About half of popups come on four-seamers and cutters, where the batter has trouble catching up and swings just under the pitch. The rest come on softer stuff, and those pitches are usually low in the zone. I need you to do some 3D visualization in your head here, because my diagram is not very good:

On the left is a perfectly level bat, parallel with the front of the plate. Now imagine you’re angling your bat downward and you get just underneath the ball. If your bat is angled toward the opposite field or, as in the middle example, straight toward center field, you’ll likely just foul the ball off behind you or into the opposite field stands. Once you angle it toward the pull side, however, it can stay fair, bouncing up and toward the opposite field. Please imagine that the bat on the right looks so funky because it’s foreshortened, pointed out toward the first baseman. Taveras can show us what that looks like in the real world:

If his Attack Direction were zero, he would’ve fouled the ball up and into the stands down the third base line. He only kept it fair because of his Attack Direction of 18 degrees.

Look, I don’t have a big takeaway here. I just think this interesting. I think it highlights the way that the angle of the bat informs even the most mundane batted balls. If you’d asked me yesterday whether it’s possible to go the opposite way while your bat was angled toward the pull side, I would’ve had to think about it, but my first reaction would’ve been to say no. The bat and ball move through space so quickly that they can be hard to track, but the bat tracking metrics help explain why exactly Taveras pops out so very, very often, and how it’s even possible to hit a ball like that in the first place.
