If you’ve read a lot of my work here, you probably know that I’m a huge fan of bunting. Some bunting, at least — I’m not talking about bone-headed sacrifices at the altar of small ball. There’s just something satisfying about a well-placed bunt, pushed past the pitcher and to an open space vacated by the defense. Bunts against the shift are a delight. Bunts not against the shift, where the hitter is simply better at bunting than the defense is at defending, are great too. This article is not about one of those bunts.

On Friday night, the Dodgers were locked in a tight battle. Runs had been hard to come by against opposing starter Ian Anderson, though Julio Urías was doing his part to keep the team in the game, surrendering only a solo home run through four innings. In the top of the fifth, Urías got a chance to help the team on the offensive end as well. With runners on first and third and the game tied after a close play at the plate, he stepped up to bat with one out in the inning.

Urías isn’t a bad hitter, at least as far as pitchers go. He sports a career line of .175/.188/.190, a fair sight better than the overall .124/.143/.159 line across baseball over the course of his career. Still, he’s an awful hitter, as far as major league hitters go. Dave Roberts called for a bunt. Read the rest of this entry »

Jordan Montgomery put together a solid outing on Wednesday night. In 6.1 innings of work, he struck out six Rays and walked only two. He did get tagged for five hits, but avoided allowing any home runs, which made the whole package work admirably. He gave up three runs, but with a little defensive prowess, things could have gone even better; two of those three were unearned.

That kind of game happens all the time these days. On the other hand, that particular game has never happened before. That exact box score line — 6.1 innings pitched, six strikeouts, two walks, five hits, no homers, one earned run and three total runs — had never occurred in the more than 380,000 starts since 1913, the first year where earned runs were recorded, as James Smyth pointed out:

I’ll level with you: I had a hard time believing Smyth at first. That line is so middle-of-the-road. Everything about it feels like a common enough occurrence. There are no truly strange parts in that score, nothing that stands out as an obviously rare feat. An easy example: Carlos Martínez also recorded a unique line on Wednesday. His was altogether stranger: 0.2 innings pitched, one strikeout, four walks, and 10 earned runs without a homer or an unearned run. That just sounds like an unprecedented start.

Mike Shildt had a decision to make. It was only the first inning, but the Brewers were all over Daniel Ponce de Leon. They’d already scored three times, and had runners on second and third for number eight hitter Luis Urías. A hit here could break the game open, so Shildt took a risk and intentionally walked Urías. With a pitcher batting next, maybe he could salvage the inning.

There was just one problem: Daniel Ponce de Leon was pitching. His 11.6% walk rate this year has actually lowered his career mark. Not only that, but he’d already walked a batter unintentionally this inning, though it’s unclear whether that’s predictive. Either way, though, whoops:

Maybe that was a strike, and maybe it wasn’t. In any case, it turned into a run, and the game eventually turned into a Brewers rout. The Cardinals scored only three runs; as it turns out, the first inning was all Milwaukee needed. Urías didn’t have a hit on the day, not that that’s a particularly telling statistic.

Normally, I’d break down the pros and cons of Shildt’s decision in minute detail. Avoiding Urías and his career .318 OBP to face a pitcher seems good. Turning a walk into a run with Ponce de Leon on the mound seems bad. It’s certainly not a slam dunk in either direction. Read the rest of this entry »

Normally, I’d write some cutesy introduction to this article, maybe regale you with a fun anecdote from my life or make a bad joke to keep the mood light. Today, there’s no time. Francisco Lindor is hitting poorly this year, and we need to get to the bottom of it.

When stars slump early in the season, it’s often easy to see a culprit. Maybe they’re swinging out of their shoes and running a huge strikeout rate. Maybe they’re victims of bad batted ball luck. Maybe they’re playing hurt. In Lindor’s case, the problem is power. Now 195 plate appearances into the season, he’s hit five doubles and four home runs. Those are both by far the worst rates of his career, and combined with a .216 BABIP, they’ve resulted in a desultory batting line.

Easy, right? Lindor stopped hitting the ball hard, so now he’s bad. Only, he’s not:

So much for the lazy analysis — and to be clear, using average exit velocity is absolutely lazy. Whatever’s going wrong, it’s more complicated than a simple power outage. Read the rest of this entry »

You won’t find many joint Yankees/Mets fans, but if such a bizarre chimera exists, it’s been a rough few days for pitching health. On Tuesday, Noah Syndergaard made a scheduled rehab start for the St. Lucie Mets. He departed after only an inning, and he’s now been shut down for six weeks. Meanwhile, Corey Kluber made his first start since no-hitting the Rangers, only to leave after three innings. The Yankees placed Kluber on the Injured List and announced that he won’t throw for at least four weeks, with a return date still unknown.

Weird hypothetical New York fans aside, there’s an obvious link between these two situations. Both teams are suffering greatly in the wave of injuries currently sweeping baseball, and how both teams deal with the loss of their pitcher will do a lot to determine the outcome of their respective East divisions. Injury management is nothing new, but these two come at particularly pivotal times for both teams.

Syndergaard’s setback isn’t immediately devastating to the Mets. He was still likely more than a month away from returning to the major leagues, and the Mets planned around his absence. They acquired pitching in bulk this offseason; Taijuan Walker, Joey Lucchesi, Carlos Carrasco, and Jordan Yamamoto are all newcomers who the team expected to provide some coverage this season.

With Jacob deGrom looking no worse for the wear after a brief IL stint, the Mets are fine at the top of their rotation. Marcus Stroman, too, has been solid. Things dip from there — Walker, Carrasco, and Yamamoto are all on the IL, and Carrasco hasn’t pitched yet this year — but deGrom and a reasonable followup is all you need for an acceptable rotation. Walker will likely be back soon, to boot — he’s already throwing live batting practice. Read the rest of this entry »

Zack Wheeler signed a big contract before the 2020 season, and if we’re being honest, the Phillies paid for potential. That’s not to say Wheeler wasn’t an effective starter with the Mets, but his career numbers — a 3.77 ERA, a 3.71 FIP, a 22.8% strikeout rate, and an 8.5% walk rate — didn’t scream ace.

His stuff, on the other hand, spoke loudly. An upper-90s fastball and lower-90s slider invite comparisons with Jacob deGrom, and his curveball prevents batters from sitting on a single breaking ball. If you could design a pitcher in a lab — well, fine, you might come up with deGrom or Gerrit Cole. But if you ended up with Wheeler, you’d certainly be happy with your work.

When a pitcher’s results — and again, they were good results — fall short of what you’d expect from their stuff, any stretch of better outcomes feels like a tantalizing glimpse at what a breakthrough might look like. At this point, however, it’s not a glimpse: Wheeler has fully broken out into the ace the Phillies hoped for when they signed him.

Consider this: since leaving the Mets, Wheeler has the 10th-best ERA in baseball. It’s not some fluky sequencing effect, either. He has the eighth-best FIP in the game over that time frame, the 17th-best xFIP, and the 17th-best SIERA, another advanced ERA estimator. He’s done all of that while throwing the third-most innings in the game, behind only Shane Bieber and Aaron Civale. That combination of skill and volume puts him sixth among all starters in WAR over that time frame, in a virtual tie with Cole. Read the rest of this entry »

I’ll spare you the description of how I came up with the idea for this article. There was a lot of Alex Rodriguez’s announcing involved, and this is a family website, so my opinions on that will remain undiscussed. The point is, though, that it made me wonder about something I used to take for granted but have increasingly questioned: how do pitchers change their game plan with a runner on third base?

Depending on who you talk to, it might matter a lot or a little. Maybe pitchers won’t be willing to bounce one. Maybe they’ll pitch to a strikeout (assuming fewer than two outs), trying to keep the run from scoring. Maybe pitchers will completely ignore the runner on third and pitch normally. I’m legitimately uncertain. Not I think it’s 50% likely to be one and 50% likely to be the other — I have absolutely no idea how to weigh the relevant probabilities.

First things first; what about those bounced pitches? This is a classic announcer trope, but it’s a trope for a reason; throwing a pitch in the dirt really is more dangerous with a runner on third. Through the magic of run expectancy tables, we can see how much a one-base advancement costs the fielding team, based on whether there’s a runner on first, second, or third (I ignored other base/out states for brevity’s sake):

With no one out, everything is more or less the same; that runner on third was pretty likely to score anyway, in fact. As the outs pile up, allowing the runner from third to score hurts more and more — quite logical. Read the rest of this entry »

Last week, I laid out some broad categorizations of what makes a slider effective, when viewed in the aggregate. As a quick recap: The most important single characteristic is hitting the corners of the strike zone. If you have a slider with plus horizontal movement, it’s also okay to miss over the middle of the plate. The middle of the plate is a great location early, but a poor location late in counts. There’s more, but those were the key findings.

That analysis left some additional factors out, because there are only so many tables you can fit into an article before it all starts to look the same. Additionally, some of those factors are beyond the scope of this analysis. Sequencing and tunneling, for example, are too complex to reduce to a two-dimensional grid. Deception might be even more confusing; I’d struggle to quantify it at all, let alone simplify it into a few buckets for analysis.

Today, I’d like to look at the rest of the factors I found easy to quantify and analyze. First, let’s talk about pitch movement. Last week, I looked at horizontal movement, because that’s the classic action we associate with a slider. It’s not the only type that pitchers throw, however. Sliders are such a broad category of pitch that they encompass pitches that mostly break sideways, mostly break down (at least, relative to a fastball), or have some mixture of the two.
