Jose Altuve takes off, running as fast as he can down the line. The throw is coming in faster, sailing toward the bag. You can tell it’s going to be a close call, and indeed it is. The umpire extends his arms, signaling safe, and the crowd erupts into either emphatic cheers or cacophonous boos, depending on whether this hypothetical call takes place in Houston or Philadelphia. The whole play lasts only a few short seconds, but it’s one of the most thrilling moments of the entire game.

What I am describing is an infield hit — one of the most overlooked plays in baseball. It’s not surprising that home runs, extra-base hits and the like get a little more attention, especially since infield hits are just as often the result of poor defense or a lucky bounce as they are the result of true offensive skill. Yet as individual plays, infield singles are exactly what make baseball so exciting. There are few batted ball events as highly suspenseful as those in which an infield hit is possible. Those four to five seconds between the contact and the call can get your heart racing nearly as fast as the runner himself. Infield hits represent a true battle between batter, fielder, and even the field itself. On top of that, the ever-present possibility of an infield single is exactly what makes every routine ground ball worth watching.

This year, we have the privilege of watching two of the very best infield hitters in the game face off in the World Series. Altuve and Jean Segura are the active leaders in infield hits, the former with 247 and the latter right behind him with 244. They both passed Elvis Andrus on the active leaderboard this season, who himself reached the top of the leaderboard when Hunter Pence retired in 2020. FanGraphs began tracking infield hits in 2002, and in that time Segura and Altuve each rank among the top ten. Both just 32 years old, they have plenty of time to climb the ranks, too. Within a few years, they should find themselves second and third behind only infield hit god Ichiro Suzuki. Now if you don’t mind, I’d like to a moment to appreciate how they both got here.

Hello there! Here’s a graph.

Were you not geared up for such a quick graph? Did I blow it right by you? That was kind of the point. The graph shows the run value of fastballs, bucketed in 1-mph increments. Over the past four seasons, for every 100 fastballs thrown, one tick of velocity has been worth roughly an eighth of a run. The lesson? Throw your fastballs fast.

I’ll stick to fastballs in this article, but I should mention that harder soft stuff is also associated with better outcomes, though the correlation is weaker and the effect is less dramatic. My number crunching indicates that over 100 breaking and offspeed pitches, an extra mile per hour is worth roughly 1/16 of a run. Read the rest of this entry »

Every October, I eagerly await the latest installment of Jay Jaffe’s series about the state of starting pitching in the playoffs (his look at relievers is also a highlight). Last year, that waiting was almost rubbernecking; I wanted to see how absurdly short the postseason starts had gotten, and I wasn’t disappointed – thanks, opener Corey Knebel. This year, I was excited to see a rebound because I’m a sucker for playoff pitching duels. Again, I wasn’t disappointed; as Jay noted, start length has exploded this year, to the highest mark since 2019 and second-highest since ’16.

That tracks perfectly with my experience of this year’s slate of games. Sure, there were some games like the deciding Padres/Phillies clash where neither starter escaped the first inning, but for the first time in ages, aces pitching into the seventh has felt more like the rule than the exception this year. Yu Darvish totaled 25 innings across four starts. Zack Wheeler has amassed 25.1 innings in four starts, and he’s coming back for more. Framber Valdez and Joe Musgrove have each averaged more than six innings per start. Six is the new seven; in modern baseball, these qualify as workhorse performances.

You should read Jay’s article if you haven’t already. It’s one of my favorite recurring features — it’s that and my postseason managerial report cards, except with Jay’s series, I get the great pleasure of reading instead of having to pore over every game log countless times myself. When you’re done reading Jay, though, I have a treat: I got my hands on a database of postseason game logs, which means I can do some fun permutations and take a closer look at this season’s postseason starters.

Though the short and ugly starts of Bailey Falter and Mike Clevinger in Game 4 of the NLCS put a small dent in the numbers, thus far in the postseason we’ve seen a welcome rebound when it comes to starters preventing runs and pitching deeper into games relative to recent years. After two postseasons in which relievers threw more than half of all innings, starters have reclaimed their rightful spot atop the marquee. Even so, when it comes to October, the relievers we’ve seen have been stingier and more dominant than at any time in recent years. Thankfully, we’re seeing fewer of them — meaning fewer pitching changes and less dead time — but that’s of cold comfort to both the Mariners and Yankees.

As you can probably guess, that’s because Houston’s relief corps has been so overwhelming thus far. The Astros are 7-0 in this postseason, and while their starting pitching has been a major part of the story, their relievers have held opponents to just three runs in 33 innings (a 0.82 ERA) and a .127/.207/.227 line, with a 34.7% strikeout rate. As old friend Mike Petriello wrote recently, the staff — not just the bullpen — doesn’t have a weak link, even without having a late-inning lefty. Read the rest of this entry »

No matter how many photo ops he posed for with the retiring Albert Pujols and Yadier Molina, no matter how many cameos he made in the broadcast booth, Adam Wainwright never actually said that 2022 would be his last season in professional baseball. And sure enough, as first reported by Derrick Goold of the St. Louis Post-Dispatch, Wainwright will return to the Cardinals in 2023.

Surely, if Wainwright were to pitch anywhere this year, it would be here. The Cardinals, perhaps by dint of producing so many memorable players in this century, do seem to be uniquely sentimental about their old guys. And Wainwright has been pitching there so long he probably still refers to Missouri as “French Louisiana.” Still, this is no mere victory lap. Wainwright is not the all-spinning, all-conquering ace he was 10–12 years ago, but he can still pitch. This past year, in a season during which he turned 41, he finished second on the Cardinals in innings and strikeouts and 13th and 32nd in the entire league in innings and ERA-, respectively. That’s quite impressive for someone who’s older than Blade Runner.

There are two main questions regarding Wainwright’s outlook this year: What can one last season do for him; and what can he do for the Cardinals? Read the rest of this entry »

Jordan Lawlar’s fifth stop in what was essentially his first professional season ended prematurely on Friday. Playing for the Arizona Fall League’s Salt River Rafters, the 20-year-old shortstop suffered a fractured left scapula after being plunked by a pitch. The injury — the second to put him out of action since he was taken with the sixth overall pick of the 2021 draft — will leave him on the shelf for a reported six to eight weeks. Fourteen months ago, he tore a labrum in the same shoulder after just a pair of games with the Arizona Diamondbacks’ rookie-league entry.

The progress he’s made in the interim is a testament to his talent. Advancing from the Arizona Complex League to Double-A Amarillo, with two stops in-between, Lawlar slashed .303/.401/.509 with a 138 wRC+ and 16 home runs in 459 plate appearances this season. A self-described “pure hitter who likes to just be athletic in the box,” the Dallas-area native is currently No. 42 in our Top 100 Prospects rankings.

Veronica Gajownik knows him well. An outfield and hitting coach in the Diamondbacks system, the former Team USA infielder worked with Lawlar in Amarillo this year, and more recently in the AFL.

“He wants to get better,” said Gajownik, who is on Salt River’s coaching staff. “He has a very open mind, and the determination to do what it takes to get to the big leagues. The effort level is great to see from someone his age.” Read the rest of this entry »

Welcome to Part 2 of my new series, How Did Jose Altuve Hit in the Last 36 Innings? For those of you who missed Part 1, the answer last time was, well, badly enough to write a whole article about it!

Here in Part 2, I’m happy to report that Altuve’s performance over the most recent 36 innings has been upgraded to “still bad, but with reasons for optimism.”

Before we dig in, I should probably mention that Altuve is excellent. His playoff struggles are notable because he’s normally so fantastic at the plate. He posted a 164 wRC+ this year, fourth among qualified batters. He’s a great hitter. Now let’s talk about why he’s not hitting so great right now. Read the rest of this entry »

Take a look at the Astros’ bullpen in the ALCS against the Yankees. Do you see anything odd about it? And no, this isn’t an article complaining about the fact that they rostered nine relievers in a seven-game series with multiple off days. Rather, it’s the fact that all nine relievers are right-handed that sets them apart from every other playoff team this season, and nearly every playoff team in recent memory:

This trend was largely true during the regular season as well. Despite leading the majors in bullpen ERA and FIP, just 48.1 of their 495.1 relief innings came from southpaws. Back in April, their Opening Day roster included 10 relievers, only one of whom, Blake Taylor, is a lefty. Taylor pitched just 19 innings with an average ERA, but walked more batters than he struck out. In June, he was placed on the IL with an elbow injury and pitched the rest of the season in Triple-A after he recovered. Aside from a cup of coffee from rookie Parker Mushinski, the remaining lefty innings came from deadline acquisition Will Smith, who posted a solid 3.27 ERA and 2.66 FIP in 22 innings down the stretch. But all three have been absent from their playoff rosters so far, with the Astros opting for right-handed pitchers instead.

This dearth of lefties clearly hasn’t inhibited the Astros’ success – through seven games, their bullpen has allowed just three runs in 33 innings, including a dozen scoreless frames to clinch their final victory of the ALDS. So how have the Astros dealt with their opponents’ left-handed hitters? For starters, it helps that no one they’ve had to face so far has been particularly vulnerable to lefties. Hitters in the opposing Division Series like Josh Naylor are great against righties and unplayable against lefties, but that hasn’t been the case with the Astros’ opponents so far:

While hitters like Rizzo and Carpenter don’t have career reverse splits like they did in 2022, they’ve only been marginally worse against left-handed pitching in their time in the big leagues. In other words, neither team had hitters that might inspire a manager to call on a lefty specialist. But the Astros’ effectiveness against lefties doesn’t just come from the tendencies of the hitters they’ve faced. Houston’s relievers are also well equipped to neutralize both left- and right-handed hitters. Consider the 2022 platoon splits of each reliever on the roster:

Seven of the nine righties in Houston’s bullpen actually fared better against lefties than righties in 2022, and the only one with a pronounced weakness against lefties – Martinez – has yet to appear in a postseason game. Lefties slashed just .207/.269/.341 against this group during the regular season, posting a .270 wOBA compared to the .284 wOBA right-handed hitters produced against them. Both of these numbers are significantly better than the league as a whole – across the majors, right-handed relievers allowed a .310 wOBA to lefties and a .307 wOBA to righties in 2022. But the fact that the Astros’ top five relievers by innings pitched all ran reverse splits during the regular season is particularly important, and shows the value in relievers who can deal with any type of hitter, especially in the era of the three-batter minimum.

Now, we know that reverse splits can sometimes be unreliable in a small, single-season sample. But in addition to the fact that four of these pitchers – Pressly, Montero, Urquidy, and Abreu – have career reverse splits over a multi-season stretch, it’s still valuable to consider the methods the Astros use to make their relievers so effective against potent lefties.

Much of the Astros’ success in opposite-handed matchups comes from their relievers changing their pitch mix depending on the handedness of the batter. One way that pitchers attempt to limit their platoon splits is by throwing multiple fastballs. Cutters and four-seam fastballs tend to be close to platoon-neutral, but the horizontal run of a sinker often directs the ball into the barrel of opposite-handed hitters, giving it one of the largest splits of any pitch type. Three members of the Astros’ bullpen – Montero, Neris, and Martinez – threw both a four-seamer and a sinker during the regular season. The trio combined to throw 582 sinkers, just 13 of which were thrown to a left-handed hitter. While many pitchers with multiple fastball types throw more sinkers to same-handed opponents, few take it to the extreme levels these Astros do.

Sinkers aren’t the only pitch types that can generate platoon splits, though. Sliders can generate splits just as large – we know that sweepers are ridiculously effective against same-handed hitters, but can be risky against opposite-handed hitters for the same reason sinkers are – with their horizontal movement moving towards the opponent’s barrel. Sharper sliders with more gyroscopic spin also run platoon splits, albeit less extreme ones. The Astros’ bullpen throws a variety of different slider shapes – Garcia and Martinez dominate the horizontal movement charts, while Stanek’s moves like a bullet, and others like Pressly and Abreu have a more hybrid shape, with high marks in both sweep and velocity.

All nine Astros relievers throw a slider, ranging in frequency from Neris’ 6.6% usage rate to Abreu’s 44% clip. Combined with a few of them also throwing sinkers, everyone in this bullpen has a clear plan to get righties out. But how can they succeed with a lefty in the box? Offspeed pitches tend to run the most neutral, or even reverse platoon splits, and it’s no surprise that the Astros selectively throw their offspeed selections to lefties. These offspeed pitches consist of splitters from Neris and Stanek — it’s each pitcher’s most-used secondary — and changeups from nearly everyone else. When looking at their offspeed and slider usage in tandem, we can see very stark differences based on the batter’s handedness:

In 2022, right-handed pitchers threw sliders to right-handed opponents about 28% of the time, as compared to just 13.6% for lefty hitters. In other words, righties roughly doubled their slider usage in situations with the platoon advantage. For changeups and splitters, there’s an even larger difference. Righty hurlers used their offspeed stuff 18.4% of the time against lefties, but largely shelved those offerings against righties, dropping their usage to just 6.9%. The Astros have taken this to the extreme, almost completely ignoring their unfavorable pitches in certain matchups. Montero, Neris, Stanek, Garcia, and Urquidy use their sliders as real weapons against righties, but throw them under 3% of the time against lefties. On the other hand, Montero, Martinez, and Garcia throw tons of slowballs to lefties but almost completely ignore them when their sinkers and sliders get the job done. Replacing sliders with changeups and vice versa is far from a novel concept, but the Astros’ optimization of their relievers’ pitch usage is on another level. Of course, it helps that they don’t have to face the order multiple times (unless they’re Luis Garcia), but they’ve still managed to collectively run reverse splits as a unit all season.

While Houston has good reason to put their trust in their righties, Smith is still waiting in the wings and should be available if the Astros want to add him to their World Series roster as a specialist. It’s pretty clear he shouldn’t face a string of righties – his .362 wOBA allowed to them matches the full season performance of Carlos Correa – but is there a use for him in a situation with two outs, a lefty up, and no great pinch-hitting options, possibly in the early innings? Smith had a very solid .278 wOBA allowed to lefties in the regular season, though that actually makes him worse than all of the Astros’ high-leverage arms, only besting lower-leverage relievers like Martinez, Garcia, and Urquidy.

Let’s consider Philadelphia’s roster for a second. Houston didn’t sweat the lack of left-handed relievers on the roster the past two series because the Yankees and Mariners didn’t have any lefties who were dangerous with the platoon advantage and pedestrian without it. What about the lefty hitters on the Phillies? In addition to measuring the magnitude of their platoon splits, we should also look at their ability to handle the pitches being thrown at them. Smith is a slider-heavy lefty, especially against fellow southpaws — he throws them about two-thirds of the time. If they decide to leave Smith off the roster and continue to lean on their righties, the Phillies will likely see a lot of changeups and splitters. Using Statcast’s run values, we can measure exactly how well each hitter performed against a given pitch type to see whether the Astros would rather go with Smith or a righty against any of these hitters:

Schwarber and Marsh had sizable splits during the regular season, and both find far more success against right-handed changeups than left-handed sliders. However, in late-game situations, the Phillies have right-handed outfielder Matt Vierling, who could hit should the Astros use a lefty. Vierling has started over Marsh against lefties, and has come in for Schwarber as a defensive substitute. The red-hot Harper has a platoon split of his own, but handles breaking pitches from lefties quite well, while Stott actually ran reverse splits during the regular season. With Vierling available off the bench and the three-batter minimum to contend with, it’s hard to see a case where Smith would clearly be better than someone on the current roster. However, three relievers – Garcia, Martinez, and Urquidy – didn’t appear in a single ALCS game. While Garcia and Urquidy are likely there to provide length and potentially an emergency start, Smith could replace Martinez as the ninth reliever in the unlikely event that his services are needed. I don’t think there has ever been a bullpen with six relievers that allowed wOBAs of .240 or lower against the batter handedness they should be weaker against, and the fact that we can’t find a clear and likely use case for a lefty specialist on such a large roster is a testament to this staff’s complete control over left-handed hitters. The Astros are four wins away from a World Series championship, and the fact that they’re dominant even in areas where teams aren’t meant to be is a huge reason why.

Every year I have to remind myself that Gold Glove snubs aren’t worth getting worked up about. It’s exceedingly difficult to measure defense objectively, especially in a single season’s worth of games. It’s even harder for voters to make judgments about players’ defensive capabilities when they only watch them play a handful of games each year. Beyond that, the Gold Gloves have gone to “unworthy” players so often before that it’s foolish to be bothered by one more bad choice. Sometimes the wrong guy wins the Gold Glove, and that’s just how it goes. The players know it, the fans know it, and we all go on living.

Yet here I am, about to spend the next thousand or so words rattling on about how Jorge Mateo was snubbed for a Gold Glove. Because as troublesome as it is to evaluate defense, we do have some pretty great statistics available to help accomplish that task. And while Gold Gloves are awarded to undeserving fielders almost every season, they tend to go to those who need them the least: established stars with impressive offensive numbers. This year, the metrics make an ironclad case for Mateo at shortstop, and he would benefit from the recognition more than any of the three finalists. So against my better judgment, I’m here to write about a Gold Glove snub. If Rawlings won’t honor his dazzling defense, I’m going to have to do it myself. Read the rest of this entry »

When Juan Soto was announced as a finalist for the Gold Glove this year, I was perplexed. To say that the right fielder struggled with his defense this season would be an understatement. As recently as Game 2 of the NLCS, he was still making (or, failing to make) plays like this:

So I turned to Rawlings’ official website to get a better understanding of how Gold Gloves are won. In order to qualify for a Gold Glove, infielders and outfielders must have played in the field for at least 698 innings through their teams’ first 138 games. Maybe Soto grades out better in this subsample. In the absence of custom date ranges for advanced fielding statistics, I compared Soto to the 76 other players who were in the outfield for at least 698 innings on the season. Here is where he ranked:
