Clutch gene_ The new hand_ What the numbers say about old-school playoff beliefs

In a single nook, preventing with the power of their convictions and the collected data of many years of historic examples, are the attention take a look at and the old-fashioned. Within the different, armed with spreadsheets and chilly, exhausting numbers, are the analytics and the brand new faculty. Let’s get able to rumble.

That’s a bit overstated. Each group makes use of scouting and analytics of their quest to win. However the stability between the 2 isn’t the identical for each group. The identical could possibly be stated at this level for any pundit, analyst, or author, actually. Numbers are so ever-present in participant improvement and training processes that there aren’t many gamers left who’re strictly old-school, not less than not in major-league clubhouses.


Nonetheless, there are battlegrounds the place the old-schoolers and the numbers don’t see eye to eye. These skirmishes are effervescent up in locations like San Francisco, the place an aggressively analytics-based teaching strategy could have suffered a setback with supervisor Gabe Kapler’s firing, and Toronto, the place the gamers expressed shock about their dealing pitcher being taken out of a playoff recreation early. After which there are the numerous broadcasts and social media areas the place deeply held beliefs about baseball are being put up in opposition to what the analysis finds about these concepts.

Let’s take a look at 4 of these long-held beliefs in baseball and what the numbers reveal about them.

A clutch gene exists

Philadelphia’s Bryce Harper is clutch. We are able to see the homers, the panache, and people gaudy postseason numbers that make him one of many three or 10 better of all time, relying on the place you place the taking part in time cutoff.

“There’s a purpose you get the nickname, ‘The Showman,’” Bryson Stott stated about Harper’s rising October legacy. “He’s simply a kind of guys the place it feels like every time you want a run, you want a success, you want a house run, he’s at all times up. After which he at all times does what he’s presupposed to do.”

In keeping with the very best analysis on the market, although, “clutch” isn’t a repeatable factor. It’s clear on the group stage that situational hitting comes and goes — you may have a number of hitters, all going in numerous instructions, coping with varied points and dealing with groups of various high quality.

That is each group’s BA w RISP by month and if it seems like a complete incomprehensible mess, sure, precisely — Mike Petriello (@mike_petriello) September 19, 2023

There’s no relationship between a group’s batting common with runs in scoring place over the past month and their batting common with runs in scoring place sooner or later. And it doesn’t assist should you take a look at the final two or three months. It’s all simply chaos.


Extra stunning to some may be that the numbers have but to point out any relationship between a particular hitter’s potential to be clutch and their future clutchiness. Sure, there’s a “clutch” stat, which seems at how gamers carry out in shut and late (high-leverage) conditions in comparison with how they carry out in much less essential conditions, and sure, Harper was first in that stat this yr. He was 52nd in 2022. He was 176th out of 188 in 2021.

These wild swings in year-to-year numbers had been replicated within the analysis. Totally different analyses have checked out how “sticky” clutch is yr to yr and have discovered just about no correlation between one yr and the subsequent. One discovered that it doesn’t exist, but when it did, it will be on the order of single-digit factors of batting common. Even the research that discovered an impact didn’t discover a big impact. Statistician Nate Silver discovered that clutch hitting was possibly two % of a participant’s general high quality (which might agree with the single-digit batting common speculation). One other research discovered that clutch exists, however you want 7,600 plate appearances within the clutch earlier than you possibly can imagine it. Harper has had 651 high-leverage plate appearances in his profession.

There’s a giant distinction between proving it doesn’t exist and never having the ability to present it exists, although, and that’s an necessary distinction. Our understanding of the physics of ball flight has modified with the development of know-how; simply take a look at the ideas of seam-shifted wake and the way that led to the sweeper pitch growth as proof. Typically, additional research leads to new findings.

What if we had a greater technique to research clutch?

“I firmly imagine that if put coronary heart displays on us within the video games, you’d discover that some persons are simply extra chill than others in large moments,” outfielder Brett Phillips informed me this yr.


Proper now, wearable tech isn’t allowed in recreation conditions, however theoretically, if it had been, we would discover that some hitters have totally different cardiac traits in high-leverage moments. Discovering that organic processes had been finally totally different between gamers in clutch conditions can be a great way to show it exists, however that can be fraught with implications relating to measuring these processes, who owns that information, and the way entrance workplaces might use that data relating to paying gamers.

For now, clutch exists in our hearts however not likely in our spreadsheets.

Pitchers get into grooves

This one is just like clutch however on the pitching facet. A pitcher is dealing, hitting his spots, cruising by way of the innings, and up comes an important determination for the supervisor. Blue Jays starter José Berríos struck out 5 whereas permitting simply three hits to the primary 11 batters he confronted in Recreation 2 of the Wild Card Collection in opposition to the Twins, and his supervisor took him out of the sport. When requested later if he understood the reasoning behind the transfer — ostensibly, the considering was that the righty was about to face a lefty for the second time within the recreation, and pitchers are progressively worse in opposition to hitters the extra they see them, and it was a must-win recreation — the pitcher stated:

“Actually, I don’t know,” Berrios stated after the sport. “However aside from that, I can’t management that. So, like I say, I did my finest … In order that’s what it’s.”

Different managers have made totally different decisions and been praised for it.

“In the event you’re making pitches, you’re going to be on the market.” How Jordan Montgomery validated Bruce Bochy’s belief in Recreation 1: — Ken Rosenthal (@Ken_Rosenthal) October 16, 2023

However historical past is suffering from individuals yelling about taking a pitcher out too early or too late. What do the numbers say in regards to the probability {that a} dealing pitcher will proceed doing what he’s doing? Largely, they are saying: “You’re solely sizzling until you’re not.” Essentially the most sturdy research about this confirmed that there was just about no distinction in seventh-inning manufacturing between pitchers who dealt for six and pitchers who weren’t dealing and that managers haven’t, as a bunch, demonstrated the power to make that call efficiently.

This flies within the face of many pitchers’ lived experiences.


“We are able to all see it. We all know it. I do know it once I’m dealing and once I’m not,” stated one veteran beginning pitcher when requested in regards to the feeling.

Once more, possibly extra analysis will change the message. There’s already been a brand new and stunning research on the topic that means that this may be a legit factor. Author and analyst Rob Arthur discovered that beginning pitchers can have the “sizzling hand” and that the easiest way to measure it’s the radar gun; when pitchers have their finest velocity, they carry out a lot better than after they don’t, and so they undergo considerably predictable streaks. A pitcher could also be essentially totally different after they have a greater fastball, and it’s not likely a sizzling hand, however that’s semantics.

The research that’s but to be accomplished (publicly, not less than) is to take Arthur’s work and see if, through the use of radar gun readings, managers might make higher in-game choices on when to take a pitcher out. Berríos? He’d thrown simply seven fastballs and so they had been all a tick increased than his seasonal common, and he ended his brief begin with the second-best fastball velocity of the season.

It’s completely doable that the numbers say he ought to’ve been left in.

A hitter can “personal” a pitcher

Rangers starter Nathan Eovaldi dispatched the primary three Astros in Recreation 2 of this yr’s ALCS in 11 pitches. Then Yordan Alvarez got here up and demolished a excessive fastball. Eovaldi dispatched eight of the subsequent 9 after which … struck out Alvarez on 5 pitches, none of them fastballs. Of their final matchup, Alvarez walked. In all three instances, the batter gave the impression to be stepping in confidently in opposition to the pitcher. With good purpose:

Yordan Alvarez is 8-for-11 in opposition to Eovaldi. — Brian McTaggart (@brianmctaggart) October 16, 2023

However we’ve additionally seen instance of the other: an excellent hitter stepping in in opposition to a nasty pitcher, with a path of defeat of their rearview mirror.

One other instance of how batter vs pitcher numbers are devoid of which means! — Eno Sarris (@enosarris) October 13, 2023

Saying that the numbers are solely meaningless isn’t fairly proper. The numbers between a batter and pitcher inform the story of what occurred previously, so there’s which means there. It’s a part of telling the story of Turner’s night time and the way good he was. By way of the narrative, batter versus pitcher numbers will help spin the yarn. However how impactful are these numbers, even in telling a narrative, in the event that they don’t have any predictive high quality?


The analysis means that, nearly at all times, previous outcomes between a particular hitter and a particular pitcher are a lot too small a pattern measurement to have any statistical which means. Tom Tango, MLBAM’s Senior Information Architect, as soon as co-authored a ebook referred to as “The E book: Taking part in the Percentages in Baseball” and after trying into the difficulty mathematically, the textual content had this to say about batter versus pitcher numbers:

… having twenty to thirty PA in opposition to an opponent is a drop within the bucket, and it tells you nearly nothing about what to anticipate. The participant has an extended historical past, say 1,500 PA, in opposition to the remainder of the league. Any method you slice it, you possibly can’t equate, and even evaluate, twenty-five PA in opposition to one opponent to 1,500PA in opposition to the remainder of the league. … When a specific batter has confronted a specific pitcher 2 hundred or 300 occasions, come again and we’ll speak. Perhaps.

Put this manner, it makes intuitive and statistical sense, however that isn’t to say that different analysis doesn’t present us with some asterisks.

Again in 2013, Andrew Koo at Baseball Prospectus observed that the Oakland Athletics had been loading up with fly-ball hitters and linked that with a passage in “The E book” that identified that fly-ball hitters are particularly good in opposition to ground-ball pitchers to counsel that the A’s had been countering the league’s ground-ball pitchers with hitters who had swing paths that would elevate these low pitches.

I talked to then-Mariners starter Chris Younger forward of a 2014 begin in opposition to these Athletics and informed him throwing his high-80s fastball up within the zone was daring, contemplating the chance of homers up there.

“That’s your opinion,” he informed me. “I’ll present you a chart on each hitter that reveals you that almost all hitters have a gap within the zone up.”

He then scrolled by way of warmth maps on an iPad to point out me he wasn’t frightened about excessive fastballs in opposition to any of the A’s hitters aside from Coco Crisp. Which was fascinating, as a result of regardless of being a excessive ball hitter, Crisp was solely 3-for-15 with three singles in opposition to Younger on the time. In any case, the present GM of the Rangers was an early adopter of what number of analysts at the moment are fascinated about batter versus pitcher matchups.

Groups have gotten much more refined with this kind of evaluation. They’ve linked swing paths to pitcher strengths and even began incorporating biomechanical markers of their batter versus pitcher fashions. Think about one thing alongside the strains of: this hitter’s hips commit early, however his fingers are adjustable so he’s theoretically higher in opposition to this pitcher’s changeups than breaking balls with larger motion profiles. When you begin entering into course of versus course of comparisons, you possibly can doubtlessly begin to mannequin that batter versus pitcher matchup and say one thing predictive a few future interplay.


However that’s much more sophisticated than saying this man is 3-for-10 off that pitcher.

Hitters get chilly after 4 days off

After a divisional spherical by which three of the 4 groups with byes misplaced — and did so whereas seeing their bats go ice chilly — this perception is probably probably the most contentious. It’s undoubtedly true that Atlanta, after being among the finest offenses of all time throughout the common season, hit .186/.255/.264 of their brief collection in opposition to the Phillies, and that the Dodgers hit solely .177/.248/.250 in opposition to the Diamondbacks. It’s additionally true that baseball is probably the most chaotic sport.

Something can occur in a brief collection, too. One research estimated that for MLB to match the NBA’s price of the better-ranked group advancing within the playoffs, they’d need to play a best-of-75 collection, so it’s doable even the American League East’s 11-game dropping streak might all be as a result of likelihood.

Subsequently, learning whether or not gamers get chilly throughout these layoffs is fraught with points. Ben Clemens at FanGraphs discovered that groups with four-plus days of relaxation are 24-11 in opposition to groups with two or fewer days of relaxation, and that quantity is 21-10 within the Wild Card period — and that’s by way of this yr, so it doesn’t counsel that groups do poorly general with byes. That is sensible as a result of it offers their pitchers time to relaxation and get well, but it surely additionally doesn’t take a look at hitters particularly.

“I’m a agency believer that greater than three days off of dealing with a reside pitcher can solely harm you,” stated Giants outfielder Mitch Haniger this week. “We simply by no means do it aside from the All-Star break, and most guys discuss how they really feel like crap within the field popping out of the break. A number of days off can’t assist your timing. It could assist your physique or thoughts.”

Once more, the numbers don’t again the subjective expertise. Due to STATS Carry out, now we have baseball’s OPS on the day after the break, in comparison with the season general, in every of the final three years.

Season Seasonal OPS First Day after ASG 2021 0.728 0.793 2022 0.706 0.772 2023 0.734 0.748

The August OPS throughout this pattern was .731, so it doesn’t appear to be hitters endure as a bunch popping out of the All-Star Recreation. Plus, groups with byes have methods to maintain their hitters contemporary.


“The groups that had the Wild Card off had been understanding and certain getting reside at-bats throughout the downtime. And in the event that they weren’t, that was a mistake,” stated not too long ago retired hitter Jed Lowrie earlier this week. Tommy Pham echoed the sentiment, saying it was on the coaches to assist hold the gamers sharp throughout downtime.

This one is apparent, although: there’s extra analysis required, and the gamers speaking about getting chilly ought to be thought of. Those that work on how the physique adapts to its peak outcomes counsel that some diversifications — like peak dash velocity — can disappear inside as quickly as 5 days. However once more, can coaching hold these diversifications with out the profit ofthe finest reside pitching? Do you need to face somebody pretty much as good as Zack Wheeler reside 5 days earlier than you face him, or can a lesser pitcher throwing reside BP enable you hold your timing?

“No good reply,” stated Diamondbacks third baseman Evan Longoria.

And that’s an necessary factor to recollect: the numbers solely give us their absolute best reply proper now. As information and tech enhance, the solutions would possibly change. There’s an asterisk on every of those arguments that factors to future analysis and extra nuanced truths. The collective beliefs of the gamers engaged within the recreation ought to by no means be discounted absolutely. As a substitute, these disagreements ought to show that there’s extra work to be accomplished right here, extra analysis to be explored and that these arguments ought to proceed evolving.
