What Occurred to All These Steals of Third Base?

Athletes like Elly De La Cruz can skew our notion of actuality. His highly effective arm makes most shortstops appear to be they throw with a moist noodle. His 99th-percentile dash pace makes most different baserunners appear to be they’re working on sand. His tall body, which our web site in some way lists at 6-foot-2, makes that man on Hinge who claims he’s 6-foot-2 appear to be he’s really 5-foot-8. Oh, and his 13 steals of third base this 12 months may make you assume steals of third are at an all-time excessive, which couldn’t be farther from the reality.

As a fan of extremely particular baseball stats – a daring assertion to make on this web site, I do know – I prefer to examine in on the stolen base charges at every bag. Virtually talking, which means I pay notably shut consideration to steals of third, the oft-forgotten center baby of stolen bases. Steals of third are too frequent to obtain the identical quantity of consideration as steals of house; on the identical time, they’re rare sufficient that they’ll at all times be overshadowed by the sheer variety of second-base steals. Steals of house are virtually assured to make tomorrow morning’s spotlight reel. Steals of second outnumber all others and thus dictate league-wide stolen base developments yearly. Steals of third are caught within the center, and that’s very true this season as their siblings are taking much more of the glory than regular.

The stolen base success price at house (16-for-29, 55.2%) is the very best it’s been since no less than 1969. Certainly, it’s above 50% for solely the second time in that span. As well as, runners are on tempo to steal house 36 occasions this 12 months, which might rank second within the divisional period and effectively inside shouting distance of first (38 SBH in 1998). In the meantime, the general stolen base price (i.e. steals per recreation) can also be on the rise, primarily pushed by a rise in steals of second. The league is on tempo to steal second base 166 extra occasions in 2024 than it did final 12 months, a 5.6% enhance, as runners proceed to check the boundaries of the New Guidelines™.

Nonetheless, these extra conspicuous developments are shrouding what could be probably the most fascinating stolen base development of the 12 months. Steals of third are method down in comparison with final season, whereas the success price has fallen to pre-rule change ranges:

I first picked up on this peculiarity a few weeks into the season. Ben Clemens wrote about league-wide stolen base developments on April 11, noting that steals per recreation had not elevated the way in which many presumed they might. Somewhat, baserunners have been swiping luggage rather less incessantly than that they had the 12 months earlier than. I used to be stunned to learn this, so I went digging into the stolen base charges at every bag. That’s how I observed that steals of second base (SB2) weren’t down, no less than not by a significant quantity. Stolen bases at third (SB3), however, have been so few and much between that the shortage of SB3 was making a dent within the general numbers.

By video games on April 11, the league was on tempo for 39 fewer steals of second (a 1.31% lower) in 13 extra makes an attempt (a 0.3% enhance) in comparison with final 12 months. At third base, nonetheless, the league was on tempo for 124 fewer steals (a 24.3% lower) in 153 fewer makes an attempt (a 25.4% lower). These have been dramatic numbers, giant sufficient to pique my curiosity even in such a small pattern dimension. Nonetheless, I knew I wanted to attend longer earlier than drawing any conclusions.

Quick ahead a month of baseball – from Spencer Strider’s devastating elbow surgical procedure to Paul Skenes’s thrilling debut – and the general stolen base price was trying a lot more healthy. By video games on Might 12, the league was on tempo to surpass its stolen base complete from 2023 by greater than 100 steals. Furthermore, that all-encompassing quantity doesn’t do justice to the rise in stolen bases at second. Simply previous the quarter mark of the season, baserunners have been on tempo to steal second 225 extra occasions than that they had the 12 months earlier than. But, as you may need guessed, that meant the numbers at third weren’t a lot better than that they had been a month prior; the league was nonetheless on tempo for a 25% lower in SB3. One factor had modified, nonetheless. Runners have been making an attempt to steal third a little bit extra usually; they simply weren’t succeeding. Between April 11 and Might 12, baserunners tried to steal third 90 occasions in 421 video games. That’s not to date off the tempo from 2023 (605 makes an attempt in 2,430 video games). Sadly for these runners, they have been profitable solely 66 occasions (73.3% success price). That’s an incredibly low conversion price. The final time the SB3 success price was so low over a full season was in 2002:

Quick ahead once more – previous the discharge of bat monitoring knowledge and that epic Yankees-Dodgers collection – and it’s getting more durable and more durable to disregard this development. Between Might 12 and immediately, the SB3 success price is up barely, however makes an attempt have gone down once more. Thus, the league remains to be on tempo for a 24.1% drop-off in comparison with final season. In the meantime, the SB3 success price on the 12 months is just 77.8%. That’s proper round the place the success price hovered earlier than the rule adjustments; from 2015 to 2022, it by no means rose above 78.8% or fell beneath 76.7%. However in 2023, it jumped to 84.3%.

To be clear, I’m not stunned the SB3 success price is regressing. Evidently, the league decided the best SB3 success price was someplace round 77%, and there’s no cause the foundations adjustments would considerably have an effect on that. What’s complicated is that the SB3 success price and try price are a lot decrease than they have been final season. In principle, the issue with a excessive stolen base success price is that it suggests runners aren’t stealing sufficient. But, on this case, the success price is down though runners try to steal third far much less incessantly:

One attainable clarification? Tragedies of various levels have befallen all three names that stood atop the SB3 podium final season. Esteury Ruiz has been optioned and injured. Ronald Acuña Jr. is out for the season. Corbin Carroll has spent many of the 12 months in a dreadful droop; he’s at present on tempo for 28 steals, partly as a result of an on-base share that’s down by 50-plus factors, and even when he catches fireplace and his OBP surges, it’s unlikely that he’ll have sufficient base-stealing alternatives to swipe 50 once more. These three mixed for 9.2% of all SB3 final season, and their collective 87% success price boosted the league common. Their absence from the highest of the leaderboard this 12 months can’t clarify every part, however it’s not ludicrous to marvel if it’s a part of the issue. Aside from the De La Cruz of all of it.

Like I teased on the prime of this text, the 22-year-old phenom leads the majors with 13 SB3 and 15 SB3 makes an attempt, good for an 86.7% success price. That places him on tempo to steal third 29 occasions this season in 33 makes an attempt. Each of these figures would put final 12 months’s chief, Ruiz, to disgrace. He solely managed 21 SB3 in 24 bids. Moreover, though De La Cruz is in a category of his personal, he’s not doing all of the heavy lifting. The highest 5 gamers in SB3 makes an attempt this season are on tempo for extra SB3, extra SB3 makes an attempt, and a better success price than the highest 5 final season. Regardless of the clarification for the decline in SB3 could be, it has nothing to do with the fellows on the prime of the leaderboard:

SB3 numbers on the workforce degree level to an identical conclusion. The highest-two groups this 12 months – the Reds (duh) and Nationals – are on tempo for extra SB3 than final 12 months’s prime two. Nonetheless, the 28 groups ranked no. 3-30 are all on tempo for fewer SB3 than their counterparts from final season. Take into account that the median workforce final 12 months stole third base 15.5 occasions, whereas this 12 months, that median has fallen to 10.9. Equally, the median workforce success price final season was 87%; proper now, it’s 80%. On prime of that, 9 totally different groups are on monitor for no less than 12 fewer SB3 this season than final. Conversely, just one workforce, Washington, is on tempo to extend its SB3 complete by greater than 12. All that is to say that the basis explanation for the disappearing SB3 isn’t on the prime of the leaderboards, it’s in all places else.

Contemplating the downturn in SB3 is so widespread, I’m inclined to just accept the best clarification: Runners are stealing third much less actually because they’ve had fewer alternatives to take action. For one factor, the proportion of plate appearances taken by left-handed hitters this 12 months is the very best it’s been within the twenty first century. Which means there have been extra plate appearances the place the catcher has a transparent path to throw down to 3rd. Practically 35% of plate appearances this season have been taken by lefties, up from 33.7% in 2023. That will not appear to be a giant distinction, however over a full season, plate appearances shortly add up. Certainly, in comparison with 2023, the league is at present on tempo for 549 fewer PA by right-handed hitters in conditions with third base empty and a runner on second. That’s not inconsequential.

That mentioned, I feel the first clarification is that defenses have improved with regards to holding runners on second base. Accordingly, they’ve decreased the SB3 success price and, simply as critically, prevented loads of would-be third-base stealers from taking off within the first place. Good protection means fewer stolen base alternatives. Notably, we noticed an identical enchancment early final season. Runners have been profitable on 48 of their first 50 SB3 makes an attempt (96%) earlier than pitchers and catchers began to determine how one can cease them. The success price over the remainder of the season was solely 83.2%. Ultimately, the speed appeared to plateau; this article from The Athletic on August 9, 2023 reveals the SB3 success price just below 85%, and that’s just about the place it might be when the season wrapped up practically eight weeks later. Nonetheless, it was plain to see that defenses made a formidable adjustment to a troublesome scenario on the fly.

With an offseason to arrange and a full season of information to work with, it stands to cause that groups might work out how one can higher adapt to the brand new guidelines going ahead. It is a troublesome speculation to show, however, for what it’s value, we all know that pitcher pickoffs are up by 23.5% this season, and pitchers have gotten considerably higher at holding runners on first base. Sadly, Baseball Savant doesn’t have pitcher working recreation stats for second base but. Nonetheless, the Statcast baserunning stats, which take into consideration “runner place on the bottom paths,” counsel that development alternatives per recreation are down by about 5% in conditions that begin with a runner on second base. This metric solely considers development alternatives on balls in play, however all the identical, it’s additional proof that defenses have performed a greater job holding runners on second this season.

Thus, what we’re seeing proper now could be the brand new regular. Or, no less than so much nearer to regular than what we noticed final 12 months. Steals per recreation at third are nonetheless up by 31.6% in comparison with 2022, and the success price is true across the accepted break-even level. Maybe the third base gold rush of 2023 has settled down, however the brand new guidelines – and Elly De La Cruz – are persevering with to do their job to extend exercise on the basepaths between second and third.
