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 velocity makes most different baserunners appear to be they’re operating on sand. His tall body, which our web site one way or the other lists at 6-foot-2, makes that man on Hinge who claims he’s 6-foot-2 appear to be he’s truly 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 wish to verify in on the stolen base charges at every bag. Virtually talking, which means I pay significantly shut consideration to steals of third, the oft-forgotten center little one of stolen bases. Steals of third are too frequent to obtain the identical quantity of consideration as steals of residence; on the similar time, they’re rare sufficient that they’ll all the time be overshadowed by the sheer variety of second-base steals. Steals of residence are virtually assured to make tomorrow morning’s spotlight reel. Steals of second outnumber all others and thus dictate league-wide stolen base tendencies 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 ordinary.

The stolen base success charge at residence (16-for-29, 55.2%) is the very best it’s been since at the very least 1969. Certainly, it’s above 50% for solely the second time in that span. As well as, runners are on tempo to steal residence 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 charge (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 attention-grabbing stolen base development of the 12 months. Steals of third are manner down in comparison with final season, whereas the success charge 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 tendencies on April 11, noting that steals per recreation had not elevated the best way many presumed they might. Reasonably, baserunners had been swiping baggage rather less regularly than they’d the 12 months earlier than. I used to be shocked 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, at the very least not by a significant quantity. Stolen bases at third (SB3), alternatively, had been so few and much between that the dearth of SB3 was making a dent within the general numbers.

By means of 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, nevertheless, the league was on tempo for 124 fewer steals (a 24.3% lower) in 153 fewer makes an attempt (a 25.4% lower). These had been dramatic numbers, giant sufficient to pique my curiosity even in such a small pattern measurement. 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 charge was trying a lot more healthy. By means of 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 had been on tempo to steal second 225 extra occasions than they’d the 12 months earlier than. But, as you may need guessed, that meant the numbers at third weren’t significantly better than they’d been a month prior; the league was nonetheless on tempo for a 25% lower in SB3. One factor had modified, nevertheless. Runners had been attempting to steal third just a little extra typically; 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 up to now off the tempo from 2023 (605 makes an attempt in 2,430 video games). Sadly for these runners, they had been profitable solely 66 occasions (73.3% success charge). That’s a surprisingly low conversion charge. The final time the SB3 success charge was so low over a full season was in 2002:

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

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

One doable rationalization? 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 presently on tempo for 28 steals, partly as a consequence of an on-base proportion 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 charge boosted the league common. Their absence from the highest of the leaderboard this 12 months can’t clarify every little thing, 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 high 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 charge. 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 charge than the highest 5 final season. Regardless of the rationalization for the decline in SB3 could be, it has nothing to do with the fellows on the high of the leaderboard:

SB3 numbers on the staff 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 high two. Nonetheless, the 28 groups ranked no. 3-30 are all on tempo for fewer SB3 than their counterparts from final season. Think about that the median staff final 12 months stole third base 15.5 occasions, whereas this 12 months, that median has fallen to 10.9. Equally, the median staff success charge final season was 87%; proper now, it’s 80%. On high of that, 9 totally different groups are on monitor for at the very least 12 fewer SB3 this season than final. Conversely, just one staff, Washington, is on tempo to extend its SB3 complete by greater than 12. All that is to say that the foundation reason behind the disappearing SB3 isn’t on the high of the leaderboards, it’s in every single place else.

Contemplating the downturn in SB3 is so widespread, I’m inclined to just accept the only rationalization: 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 won’t seem to be a giant distinction, however over a full season, plate appearances shortly add up. Certainly, in comparison with 2023, the league is presently 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 stated, I believe the first rationalization is that defenses have improved in relation to holding runners on second base. Accordingly, they’ve decreased the SB3 success charge 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 had been profitable on 48 of their first 50 SB3 makes an attempt (96%) earlier than pitchers and catchers began to determine methods to cease them. The success charge 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 charge just below 85%, and that’s just about the place it could be when the season wrapped up almost 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 motive that groups might determine methods to 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 operating recreation stats for second base but. Nonetheless, the Statcast baserunning stats, which take note of “runner place on the bottom paths,” recommend 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 executed a greater job holding runners on second this season.

Thus, what we’re seeing proper now could be the brand new regular. Or, at the very least lots 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 charge 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.
