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 like they throw with a moist noodle. His 99th-percentile dash pace makes most different baserunners appear like they’re operating on sand. His tall body, which our web site someway lists at 6-foot-2, makes that man on Hinge who claims he’s 6-foot-2 appear like he’s truly 5-foot-8. Oh, and his 13 steals of third base this yr would possibly make you suppose 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, meaning I pay notably 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 house; on the similar 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 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 regular.

The stolen base success fee 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 yr, which might rank second within the divisional period and properly inside shouting distance of first (38 SBH in 1998). In the meantime, the general stolen base fee (i.e. steals per sport) can 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 yr, a 5.6% improve, as runners proceed to check the bounds of the New Guidelines™.

Nonetheless, these extra conspicuous developments are shrouding what is likely to be probably the most fascinating stolen base development of the yr. Steals of third are means down in comparison with final season, whereas the success fee 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 sport had not elevated the way in which many presumed they might. Relatively, baserunners have been swiping luggage rather less ceaselessly than that they had the yr 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 seen that steals of second base (SB2) weren’t down, no less than not by a significant quantity. Stolen bases at third (SB3), alternatively, have been so few and much between that the shortage of SB3 was making a dent within the total numbers.

Via 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% improve) in comparison with final yr. 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, massive 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 fee was trying a lot more healthy. Via video games on Could 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 yr earlier than. But, as you might 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 attempting to steal third a bit of extra usually; they simply weren’t succeeding. Between April 11 and Could 12, baserunners tried to steal third 90 occasions in 421 video games. That’s not thus far 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 fee). That’s an incredibly low conversion fee. The final time the SB3 success fee 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 sequence – and it’s getting more durable and more durable to disregard this development. Between Could 12 and at present, the SB3 success fee 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 fee on the yr is barely 77.8%. That’s proper round the place the success fee 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 stunned the SB3 success fee is regressing. Evidently, the league decided the best SB3 success fee was someplace round 77%, and there’s no purpose the foundations adjustments would considerably have an effect on that. What’s complicated is that the SB3 success fee and try fee are a lot decrease than they have been final season. In concept, the issue with a excessive stolen base success fee is that it suggests runners aren’t stealing sufficient. But, on this case, the success fee is down regardless that runners are trying to steal third far much less ceaselessly:

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 yr in a dreadful stoop; he’s at present on tempo for 28 steals, partly resulting from 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 fee boosted the league common. Their absence from the highest of the leaderboard this yr can’t clarify every thing, but it surely’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 fee. That places him on tempo to steal third 29 occasions this season in 33 makes an attempt. Each of these figures would put final yr’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 the next success fee than the highest 5 final season. Regardless of the clarification for the decline in SB3 is likely to be, it has nothing to do with the fellows on the high of the leaderboard:

SB3 numbers on the crew stage level to an analogous conclusion. The highest-two groups this yr – the Reds (duh) and Nationals – are on tempo for extra SB3 than final yr’s high 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 crew final yr stole third base 15.5 occasions, whereas this yr, that median has fallen to 10.9. Equally, the median crew success fee final season was 87%; proper now, it’s 80%. On high of that, 9 completely different groups are on observe for no less than 12 fewer SB3 this season than final. Conversely, just one crew, Washington, is on tempo to extend its SB3 complete by greater than 12. All that is to say that the foundation explanation for 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 simply accept the only 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 yr is the very best it’s been within the twenty first century. Meaning 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 look like an enormous distinction, however over a full season, plate appearances rapidly 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 stated, 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 fee 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 analogous 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 the right way to cease them. The success fee over the remainder of the season was solely 83.2%. Finally, the speed appeared to plateau; this article from The Athletic on August 9, 2023 exhibits the SB3 success fee just below 85%, and that’s just about the place it will be when the season wrapped up almost eight weeks later. Nonetheless, it was plain to see that defenses made a formidable adjustment to a tough state of affairs on the fly.

With an offseason to arrange and a full season of information to work with, it stands to purpose that groups may determine the right way to higher adapt to the brand new guidelines going ahead. It is a tough 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 sport stats for second base but. Nonetheless, the Statcast baserunning stats, which have in mind “runner place on the bottom paths,” counsel that development alternatives per sport 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 finished a greater job holding runners on second this season.

Thus, what we’re seeing proper now is likely to be the brand new regular. Or, no less than lots nearer to regular than what we noticed final yr. Steals per sport at third are nonetheless up by 31.6% in comparison with 2022, and the success fee 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.
