WARNING: That is going to be nerdy.
Baseball Savant printed new public bat monitoring statistics this week that cowl the final three seasons. I don’t know the place this rabbit gap goes to steer me, however I’ve a pocket book filled with preliminary concepts to discover, in order that’s what we’re going to do right here as we speak.
Mike Petriello put out a primer on the brand new metrics here. You need to learn it. When you don’t wish to do this, the gist is that the brand new metrics monitor the bat throughout a swing in relation to the ball. They measure how typically hitters swing early or late, above or under the ball, and inside or exterior the ball. Principally, are you swinging the place you’re alleged to to be able to make strong contact? We’ve this by depend, pitch kind, handedness, month, season (2023-present), venue, staff, astrological signal, Hogwarts home, and extra. Once more, I don’t know what I’m going to search out, however let’s dive in.
4-seam fastballs are designed to get hitters to swing late and swing below the ball primarily. I’ve harped on how good Payton Tolle’s fastball is time and time once more. Unsurprisingly, 62% of swings towards his fastball have been beneath the ball, the tenth highest mark out of 289 qualifiers. That quantity is up from 45% final season. Why? Most likely due to the addition of his sinker. That’s vital as a result of, regardless of his elite velocity, hitters are equipped for fastballs. They’re on time 72% of the time, 183rd of 289 qualifiers. Final season, with out a second fastball, hitters knew each the place and when to swing, which is a recipe for catastrophe. This season, there’s extra pause about the place to swing, and the contact high quality has weakened.
Elsewhere, Brayan Bello has had a trainwreck of a season. Final yr, he was extremely efficient at utilizing his sinker to get out of jams. Hitters have been “tied up” by 36% of the sinkers he threw final yr. This season, that quantity is barely 22%. What modified? The place he was throwing them.
In 2025, 55% of the sinkers he threw to righties have been on the internal third of the plate and in. This season, solely 46% of them have been in that space. The arduous hit fee towards the pitch rose from 35% to 53% over that span. That hasn’t been Bello’s solely concern this season, but it surely’s actually been certainly one of them.
What about nice pitches? Garrett Whitlock’s slider returns “flawed swings” on 30% of swings. Which means the hitter is behind schedule, lined up, or centered together with his bat. If you consider the swing in three dimensions, timing, peak, and width, it’s a swing that was 0-for-3. On whiffs, hitters miss by a median of seven.3 inches. That’s the Thirteenth-largest common miss in baseball. Fairly good!
Let’s speak about cutters. The Pink Sox love them, they usually perform in several methods. You’ll be able to throw them again door to an opposite-handed hitter, making an attempt to land for a referred to as strike. They will also be used up and in to opposite-handed hitters, making an attempt to jam them for weak contact. The previous requires hitters to not swing, so these new stats don’t give us a lot data there. The latter requires certainly one of two issues to occur. Both the pitch strikes extra in the direction of the glove aspect than the hitter expects, or they swing late and may’t get the barrel to the ball.
Brayan Bello’s cutter is a bizarre one. Towards left-handed hitters, it has an enormous swinging strike fee of twenty-two.1%. The swing monitoring numbers present us that lefties are frequently early (53% of swings, the second-highest fee amongst RHP to LHH), and by no means tied up (0%). As a result of they’re early so typically, Bello wants the ball to essentially be in on their arms the place they’ll have a tough time protecting it honest. A lot of the swings, nonetheless, have been on pitches over the plate, permitting lefties to raise and pull the ball, main to very large harm.
Payton Tolle’s cutter has been nice — 31% of right-handed swings registered as “tied up”. Righties haven’t barreled the ball up in any respect, and the one extra-base hit towards it was this double.
Observe: I’m scripting this throughout Tolle’s begin towards the Rays. One other hitter simply bounced a cutter off the plate for a double. Baseball is so unusual.
Ranger Suarez’s cutter additionally has a 21% tie up fee towards righties, although the whiff fee is far decrease. Hitters are late on 25% of their swings, permitting the ball to get in on their arms. For Tolle, they’re early 20% of the time as they search for one thing tougher, resulting in whiffs. There are not less than two methods to pores and skin a cat.
Talking of Suarez, his sinker has been glorious at jamming lefties, with a tied-up fee of 24%. That’s lagging behind Garrett Crochet, whose 40% mark towards lefties is among the many greatest in baseball. Connelly Early isn’t far behind him at 36%, which contributes to his sinker’s 56.5% floor ball fee versus lefties.
Within the bullpen, Tayron Guerrero is throwing his sinker by everybody — 38% of swings are late. Consider it or not, that isn’t how Aroldis Chapman is getting his whiffs. Hitters are on time 84% of the time towards Chapman’s sinker and 79% of the time towards his four-seam. It’s the motion that’s getting them — 52% of swings are beneath his sinker, 41% are below his four-seam.
Who haven’t I talked about but? Sonny Grey? His four-seam is hit at instances, but it surely additionally does job tying up lefties. It’s not a standard high-vertical four-seam; it has some reduce motion to it, permitting it to get in on lefties. His cutter additionally will get in on lefties, as a result of it has much more reduce than the four-seam. His sweeper and curveball each induce extremely ugly swings, like this one which Salvador Perez missed by actually over two toes.
On the hitting aspect, Masataka Yoshida leads the staff in “Good Contact” with a 38% fee. Caleb Durbin is second at 33%. Neither man is hanging out; they clearly every have nice management of the barrel. Neither man has high-end bat pace, although, so regardless of being on time and lined up, they’re not doing a ton of injury. Wilyer Abreu has been late towards fastballs, and the outcomes mirror that. He has a 25% whiff fee and .219 batting common towards them.
Alright, I believe that’s sufficient meandering from me. These things isn’t the end-all be-all of research, but it surely helps to have the ability to verify what you suppose you realize, or give context to why somebody may be slumping. Go try the leaderboard your self and let me know what you discover within the feedback. Perhaps you’ll be capable to repair the offense, or salvage a pitcher. I don’t have any pull within the group, however as soon as I wrote that Payton Tolle ought to add a sinker, and he did, so possibly somebody is paying consideration. Or possibly they aren’t, they usually got here to that conclusion on their very own. I additionally wrote that Brayan Bello can be okay as a starter, and he gave up 75 runs within the first inning the very subsequent day, so what do I do know? Okay, I’m executed meandering for actual now. I hope you loved studying this as a lot as I loved writing it.
