It’s a disgrace that “bunts are unhealthy” has develop into one of many truisms on the core of the ceaseless, foolish battle between old-fashioned and new college, stats and scouts, quantitative and qualitative evaluation strategies. It’s comprehensible, as a result of “cease bunting a lot” was one of many first inroads that sabermetric analysts made in baseball technique. However that was 25 years in the past, and whereas everybody stored repeating that very same mantra, the information on the bottom modified.
Sacrifice bunts by non-pitchers have plummeted through the years, as they need to have. Lately, the bunts which might be left, those that groups haven’t streamlined out of their sport planning, are principally the nice ones. “Bunts are unhealthy” by no means meant that in totality; it simply meant that too most of the instances that groups sacrificed outs for bases had been poor selections. That’s develop into far more clear now that pitchers don’t bat anymore. The 2022 season, the primary full 12 months of the common DH, set a report for many runs added by bunting. After a down 2023, this season was proper again close to these banner highs. So let’s recap the methods groups beat the outdated typical knowledge and assembled a 12 months of bunting that the number-crunchingest analyst on the planet may admire.
The Dying of the Worst Sac Bunts
When is an efficient time to bunt? It’s sophisticated! It will depend on the place the protection is taking part in, the rating of the sport, who’s on base, the participant on the plate, the next hitters due up, and myriad different minor elements. However there’s one overwhelming issue: There are base/out states the place bunts are nearly at all times a foul thought, and the extra you keep away from these, the higher.
Sacrifice bunting with solely a runner on first nearly by no means is smart. You’re getting only a single development, and it’s the least priceless development there may be. Getting a runner to 3rd with just one out is an admirable purpose. Shifting two runners up is even higher. Squeeze performs have big potential rewards. Shifting a man from first to second simply doesn’t measure up.
Likewise, bunting will get worse when there’s already one out within the inning. Plate appearances with runners on base are price their weight in gold within the trendy, homer-happy sport. Crooked numbers are powerful to come back by, and the best technique to get them is by stacking up alternatives to hit multi-run homers. When you have already got a runner on base, bunts are at all times suspect. Bunts that minimize out half of your remaining outs within the inning are even worse.
There are occasional circumstances the place these kind of bunts make sense. If the batter thinks they’ll beat out a success pretty typically, bunting will get higher. The weaker the hitter and the higher the next lineup, the extra enticing bunts get. Shut video games and speedy runners can tip the stability. It’s not a universally unhealthy resolution to bunt with solely a runner on first, or to bunt with a number of outs, however the increased the proportion of bunts that transfer a runner to 3rd with lower than two outs, the higher.
To get an thought of how a lot this has modified whereas eradicating pitchers from the equation, I regarded on the 2015-2019 seasons and excluded all plate appearances from the ninth spot within the batting order. That’s not an ideal method of eradicating pitchers, however it will get fairly shut. I used this to get an thought for what share of bunts got here in favorable conditions – with no less than a runner on second and nobody out.
In these years, 23.2% of bunts occurred in the very best conditions for a sacrifice. After eradicating bases-empty bunts, that are clearly a distinct animal, we’re left with bunts in conditions the place a sacrifice isn’t notably priceless. These ill-conceived bunts value groups roughly 0.1 runs per bunt, an incredibly excessive quantity. All different bunts – makes an attempt for a success or makes an attempt to maneuver a runner to 3rd with just one out – carried constructive run expectancy. It’s simply that there have been so many bunts in unhealthy spots.
In 2024, 31.7% of bunts got here in “good sacrifice” conditions, with a runner on second and nobody out. More and more, the “unhealthy sacrifice” conditions are actually about going for a single with some ancillary advantages of runner development. On-base share on bunts with runners on base is up. In 2024, 25% of the bunts with runners on base ended with the batter reaching base safely, by way of hit, failed fielder’s alternative, or error. That’s up from 22% (non-pitcher) within the 2015-2019 period, and from 17.7% from 2008 to 2012. If something, that understates it too: Loads of the worst hitters in baseball used to bat in entrance of pitchers, which restricted their bunting alternatives.
Spectacular Particular person Efforts
Jose Altuve bunted 14 instances this 12 months. 9 of these became singles. That was the very best efficiency by anybody with double-digit bunts, however it was hardly the one distinctive effort. Jake McCarthy bunted 21 instances and racked up 10 singles. Luke Raley went 7-for-12. This one from Altuve was simply excellent:
That’s to not say there have by no means been good bunters earlier than. Dee Unusual-Gordon persistently turned bunts into singles at a excessive clip. Altuve has been within the majors for some time. However the high-volume bunters in at the moment’s sport are simpler than they had been 10 years in the past within the combination. There are additionally fewer actually objectionable bunters. Francisco Lindor bunted 20 instances in 2015 and reached base safely solely 3 times. Fellow 2024 Met Jose Iglesias bunted 12 instances and reached base as soon as. There have been nonetheless some unhealthy bunters – Kevin Kiermaier and Kyle Isbel had terrible outcomes, for instance – however it’s develop into far much less widespread.
Bunting for a single is hardly the one constructive end result, after all. That’s why you bunt within the first place – as a result of bunts result in extra productive outs, on common, than swinging away. Development is extra probably and double performs are much less probably. Particular person efforts of the highest few bunters have at all times been internet constructive. Today, these high bunters are accounting for a much bigger share of general bunts, and the outcomes have improved proportionally.
Bunters Have been Already Good
Right here’s a secret: The wars had been already over. In 2002, bunters batting within the 1-8 spots within the lineup value their groups 36 runs relative to a naive expectation based mostly on the bottom/out state after they batted. In 2004, that quantity swelled to -63 runs. It was detrimental in 11 of the 12 seasons from 2000-2011, with roughly 2,000 bunts a 12 months from this cohort, which largely excludes pitchers.
The variety of non-pitcher bunt makes an attempt declined because the twenty first century progressed into its second decade. By 2015, we had been all the way down to 1,500 a 12 months or so and steadily declining. The bunts excised from the sport had been all of the lowest-value bunts, those probably to harm the batting staff. From 2012 onward, non-pitchers have produced constructive worth on their bunt makes an attempt each single 12 months. In the meantime, bunt makes an attempt have declined after which stabilized, round 1,100-1,200 per 12 months. Groups aren’t dummies – they’ve minimize out 800 bunts a 12 months, or greater than 25 per staff, and people bunts are just about all of the no-hope-for-a-single sacrifice makes an attempt that drew statistically minded people’ ire within the first place.
In that sense, you’re not likely seeing something fully new in 2024. The perfect bunters within the sport are just a little bit higher than they was, however not overwhelmingly so. They’re selecting higher spots, however not overwhelmingly so. They’re succeeding extra regularly after they purpose for a success, however good bunters have at all times been good at that. The actual change is within the bunts that aren’t taking place.
The Mariners
I’ll be trustworthy: I didn’t anticipate the Mariners to high the checklist of finest bunting groups. They appear too station-to-station, too offensively challenged, too reliant on the house run. What can I say? Appearances might be deceiving. Led by Raley, an unlikely however enthusiastic bunter, the Mariners had a league-best efficiency. This one was simply excellent:
It was an important state of affairs for a bunt. The Astros had been shifted over towards Raley’s pull aspect, which left third baseman Alex Bregman on an island protecting third and prevented him from crashing early. Raley disguised the bunt lengthy sufficient to get every thing transferring, after which used his sneaky-blazing footspeed to beat it out. It’s a masterpiece of bunting.
Victor Robles is much less about masterpieces and extra about most effort. He bunts too typically for his personal good. That results in quite a lot of iffy bunts, but additionally some gems:
That’s one other one the place studying the protection made all of the distinction. The Rays shifted their center infielders away from first, which meant a bunt previous the pitcher would go away Yandy Díaz helpless. This one additionally benefited from a little bit of defensive confusion, as many good bunts do. Who was protecting second when Díaz fielded the ball? Kind of nobody:
Hey, each little bit helps whenever you’re bunting. And whereas loads of different Mariners contributed to their success as properly – Leo Rivas and Jorge Polanco know the way to deal with a bat – I needed to shut this out with one other gem from Raley. Positive, it’s towards the White Sox, however these runs depend too. Raley is simply vicious in relation to attacking good spots to bunt:
It’s not daily that you simply see a squeeze bunt go for a no-throw single. However once more, Raley learn the protection and positioned the ball completely. Not a lot you are able to do about this:
Altuve may need the benefit in uncooked numbers, however nobody made me sit up in my seat hoping for a bunt like Raley did this 12 months. Hat tip to Davy Andrews for highlighting his hijinks early within the 12 months, and Raley simply by no means stopped going for it.
The Angels
By all rights, this text needs to be over. The Mariners had been the very best bunters this 12 months, Raley was their ringleader, and so they exemplified the best way bunts are making offenses higher in at the moment’s sport. However the Angels are altogether extra complicated and extra giffable, so I’m giving them a shout too.
You’d suppose that Ron Washington’s staff can be on the very high of the bunt fee leaderboards, however the Halos tried solely 25 bunts this 12 months, half the Mariners’ tally and seventh-lowest in baseball. The rationale why is clear: They weren’t that good at it. They weren’t the worst staff when it comes to runs added – that’d be the Nats, who had been each prolific and unhealthy at bunting this 12 months – however they had been impressively inefficient. Nobody with so few bunt makes an attempt was practically so unhealthy within the combination.
They bunted in unhealthy spots. They not often reached base even when the protection was poorly positioned. This could be the worst bunt try you’ve seen this 12 months:
Except it’s this:
The lesson: Cease with all these squeeze bunts. Except it’s towards the White Sox, that’s:
See, our story has a cheerful ending for the bunters in any case. I really like bunts, and I’m not afraid to make use of this platform to indicate it.
