Last week, Justin Choi wrote a fascinating article about sinkers. You should read it, because Justin’s stuff is great, but I’m going to summarize it here because I want to riff on it a little bit. In essence, Justin pointed out what we all kind of knew but didn’t talk about much: sinkers are much better against same-handed batters. Teams have caught on, and they’re changing usage accordingly.

Here’s a great chart from that article: the percentage of all right-handed sinkers that are thrown to right-handed batters:

That’s pretty straightforward: pitchers are increasingly using sinkers only when they have the platoon advantage. Here’s another way of looking at it: the percentage of sinkers among all pitches thrown by righties to lefties, league-wide:

In plain English, pitchers have stopped throwing sinkers when they’re faced with opposite-handed batters. Meanwhile, they’re throwing right/right sinkers as frequently as ever:

Those two charts hardly look like the same pitch, and in fact they aren’t really. Righty pitchers are actually playing two slightly different games: they’re pitching to same-handed batters and separately pitching to opposite-handed hitters. The object of both games is to get the batter out, so it’s not like the games are that different, but it’s inconceivable that the same pitches would be best against both sides.

Marcus Semien is up to his usual tricks. He’s eighth among all position players in WAR, comfortably the best on a first-place Rangers squad. For the third straight year and the fourth out of five, he’s on track to rack up four-plus WAR as one of the two best players on his team. For someone who didn’t post an above-average batting line until his seventh major league season, it’s an impressive accomplishment.

Perhaps more impressive to me: he’s doing it right under our noses, and no one seems to notice. Semien is good at everything but not in a way that adds up to a tremendous offensive line. His best skill might be durability. He’s clearly a very good player, but his particular set of skills are highlighted by the framework we grade him under. I’m interested in Semien as a player, and I’m also interested in why he’s the poster boy for both what WAR gets right and where it has limits.

Let’s start with how Semien does it. It’s fairly straightforward: he’s above average at every phase of the game. It begins with his plate discipline. To put it simply, he doesn’t make bad decisions about when to swing. In each of the past five years, he’s accomplished an impressive double: chasing fewer pitches than league average and simultaneously swinging at more in-zone pitches than league average. To state the obvious, that’s a great way to both rack up a pile of walks and avoid strikeouts. Read the rest of this entry »

Welcome to another installment of Five Things, a look at some things that caught my eye in baseball this week. As usual, I’d like to thank Zach Lowe, whose NBA column inspired me to start this one. This week has a few more things I don’t like than usual, from young players with defensive issues to young players missing the season with injury. Don’t fret, though: there’s a heaping helping of good defense, and even some amusingly awful plays for comic relief. Let’s get right to it.

1. Abysmal Defense in Winning Efforts
It’s hard to overstate how poorly the Giants fared on defense last Sunday. They kicked things off by letting a popup fall between three defenders, and that was just the beginning. They let that run score in ignominious fashion:

There’s no sugarcoating it; that was ugly. This might be worse, though:

OAKLAND – The Coliseum was rocking for the first pitch of last night’s game. A crowd of 27,759 roared as Yandy Díaz grounded out to first. “Sell the team! Sell the team! Sell the team!” The coordinated chant broke down into roars and cheers as Ryan Noda gathered up the grounder and stepped on first, kicking off the wildest Tuesday night game you could ever imagine.

The fans – 23,000 more than attended Monday night’s fixture – came out to protest owner John Fisher’s attempt to move the A’s to Las Vegas. They came out to protest Fisher’s management of the team in general. More than either of those causes, however, they came out to cheer for the A’s. As much as the team’s recent trajectory makes them hard to root for, as much as ownership and the front office seem to be steering into the skid, Oakland fans remain some of the most passionate in baseball.

If you’ve never heard of a reverse boycott before, that’s not surprising: the fans more or less improvised the idea on the fly. Jeremy Goodrich, a college student and lifelong A’s fan, created a change.org petition calling for Fisher to sell the team instead of relocating. Stu Clary, a longtime fan, saw the petition and floated the idea of selling out a weeknight game as a signal that fan support for the A’s is merely dormant, not extinct. The concept caught on almost immediately. Read the rest of this entry »

Did you know that Andy Warhol didn’t actually say “In the future, everyone will be world-famous for fifteen minutes”? I was shocked to learn the truth. Apparently, two museum employees invented the quote when they were working on a Warhol exhibit. That makes the saying more interesting to me, actually: two anonymous people creating the work of someone famous for the democratization of art is enjoyable. But I digress: the point of bringing that quote up is that Nick Anderson is well into his second fifteen minutes of fame, and I’m pretty sure that this, too, is something Warhol would approve of.

It’s hard to imagine a better pitcher getting a worse contract than the one Anderson signed this offseason. He was one of the best relievers in baseball, period, from his 2019 debut until tearing his UCL in 2021. Heck, he was top 15 in reliever WAR from 2019 to ’21, and he basically didn’t play in one of those years. Sub-3 ERA, sub-3 FIP, the fourth-highest strikeout rate in baseball (39.6%) — Anderson was an elite closer, and the Rays used him accordingly. The Braves are paying him only $875,000 this year. That’s some kind of bargain.

As Esteban Rivera detailed last November, there were reasons to doubt that Anderson would come back strong. He looked diminished in his last few appearances before hitting the IL; his biggest weapon, a fastball with excellent carry that left batters flummoxed, lost its usual carry. Vertical approach angle is all the rage in pitch design these days, and that’s the case because it neutralizes the biggest weapon hitters have: power on contact. You can’t hit a home run if you can’t hit the ball, and flat-angled four-seam fastballs are great at doing just that. Read the rest of this entry »

I hate to admit it, but I’m a bit of a grump these days. Specifically, I’m a grump about position players pitching. Every time Jay Jaffe chronicles the spread of the tactic, I get annoyed right alongside him. When some disinterested backup infielder lobs the ball in at 40 mph, I cringe. I was a fan of the rules that limited when teams can send hitters to the mound; in fact, I remember being disappointed that the rules weren’t more stringent when they first came out.

With that said, I have to take it all back now. I’m in on position players pitching – as long as we’re specifically talking about Brandon Crawford. He took the mound to close out a 13-3 Giants victory yesterday and did so in a way that position players simply don’t anymore: He tried as hard as he could.

There have already been multiple excellent breakdowns of how Crawford had always wanted to pitch and how he got the opportunity. I can’t match that kind of coverage – but I can take a different angle. He looked borderline acceptable out there, something you can’t often say of hitters taking the mound. How acceptable? Let’s do a pitch breakdown. Read the rest of this entry »

Five Things was off last week while I gallivanted around the country on vacation. Well, I’m back, and I’ve been furiously watching baseball to make up for the time I missed on the road. As such, some of these items are going to be amalgams of a few games because the same themes kept calling out to me. As always, this column was inspired by Zach Lowe of ESPN, whose basketball columns are some of the best in the business. We’ve got plenty to cover, so let’s get started.

1. Unexpected Pitching Duels
Last Thursday, the Rockies and Diamondbacks faced off in Arizona. The pregame forecast: runs galore. Zach Davies brought his 5.68 ERA to bear for the Diamondbacks (with a 5.65 FIP, it’s not like he’d been catastrophically unlucky) while Connor Seabold took the mound for the Rockies (5.94 ERA, 5.79 FIP).

Naturally, both pitchers came out in fine form. Davies started shakily but recovered to post three straight scoreless innings. Meanwhile, Seabold couldn’t miss; well-located fastballs helped him escape his first jam of the game to complete five scoreless innings:

The good times didn’t keep going – both teams scored two runs in the sixth to chase the opposing starter – but just for a moment, Davies and Seabold did their best impressions of aces. I love that kind of game, where you show up expecting a shootout and get a tense duel instead. Read the rest of this entry »

Last week at Baseball Prospectus, Rob Mains did some digging into home field advantage and found a very curious effect: home teams did worse in extra inning games than in regular-season games. More specifically, he found that home teams won roughly 54% of games overall but only roughly 52% of extra inning games. There are no two ways about it: that’s strange.

Mains looked into many potential explanations for this discrepancy: team quality, pitcher quality, games that were tied going into the ninth, and various ways of looking at how teams have adapted to the zombie runner era. Today, I thought I’d throw my hat into the ring with a slightly different way of thinking about why home teams are less successful in extras than they are overall.

My immediate thought when I heard this problem was something Ben Lindbergh mentioned on Effectively Wild: home field advantage accrues slowly, and extra innings have fewer innings than regulation. The minimum scoring increment in baseball is one run, naturally. Home field advantage is clearly less than a run per inning; it’s less than a run per game. I like to think of home field advantage as fractionally more plays going the home team’s way. A called strike here, a ball that lands in the gap instead of being caught there, and eventually one of those plays might put an extra run on the board. Read the rest of this entry »
