This time final 12 months, baseball dialogue was centered on one factor: steals. There they had been, in nice enormous portions for the primary time in many years. With disengagements and due to this fact pickoff throws restricted, males on base ran wild. They had been profitable at an enormous clip, in addition. By 12 months’s finish, final season’s 3,503 stolen bases had been probably the most in any marketing campaign of the twenty first century.
The wildest half about this statistic is that it felt like there nonetheless weren’t sufficient steals. Runners had been profitable at an 80.2% clip final 12 months. That’s fairly a bit greater than the breakeven charge of success, which bounces across the 75% mark based mostly on sport state; in any case, not all steals are created equal. Russell Carleton dug into the data and famous that runners didn’t change their aggression in any respect till they’d seen not less than one pickoff throw.
In the meantime, their success charge on the situations the place the pitcher *didn’t* throw over ballooned to almost 83%. You didn’t should be a rocket scientist to determine the place this was going. In 2024, the pondering went, runners would have extra expertise with the brand new guidelines, and due to this fact would begin taking off extra regularly, pickoff throw or no pickoff throw. Naturally, new guidelines take some time to regulate to, however this adjustment appeared fairly more likely to occur.
Thus far, although, it hasn’t. Listed below are stolen base makes an attempt per sport during the last six years. I threw in some outdated years for scale, however actually I’m solely involved with 2023 and 2024:
The models on this one are stolen base makes an attempt per staff per sport, which is probably the most intuitive manner to consider it for me. Runners try to steal barely much less regularly. So is their success charge going up? Nope:
That’s bizarre. This stuff are, not less than theoretically, working in opposition. The extra bases runners attempt to steal, the more serious their alternatives get, as a result of they had been already taking all the great ones. Likewise, if runners get extra cautious, they’re presumably giving up the toughest alternatives for steals fairly than the best, which implies success charge ought to enhance. We aren’t seeing both impact to this point, although.
What provides? I can inform you that pickoff throws have elevated from 1.96 per staff per sport to 2.13, however that’s not precisely an enormous change. It’s additionally not clear which manner that impact ought to go; in final 12 months’s information, extra pickoff throws meant extra makes an attempt however a decrease success charge. This 12 months, that hasn’t been the case. Pitchers are throwing over to first (and, often, second and third) extra regularly, however they aren’t paying for it with elevated stolen base makes an attempt. One observe: I excluded pickoff throws that resulted in an error and base development, as a result of these don’t lead to elevated probabilities of a steal; the bottom has already been conceded by the error.
One potential motive for this working slowdown is that the blokes behind the plate are getting higher. In the event you take all of the throws all the way down to second by all of the catchers in baseball this 12 months and common them up, the pop time throughout the majors is 1.945 seconds. Final 12 months, that quantity was 1.96 seconds. In 2022, it stood at 1.98 seconds. In different phrases, catchers are getting the ball all the way down to second base extra quickly than ever. That’s coming in two locations. Current catchers are throwing quicker, however the inhabitants of catchers can also be altering. Catchers who’ve not less than one recorded throw in 2023 and 2024 have decreased their pop time by .005 seconds on (weighted) common. That’s tiny, after all. The remainder of the advance has come from guys with massive arms getting extra taking part in time behind the dish.
One other attainable motive: Perhaps there are simply fewer possibilities to steal. Leaguewide, OBP sits at .318 to this point this 12 months, down from .320 final 12 months. That’s most likely not sufficient of a change to matter, however I nonetheless seemed into it. To take action, I scraped all of this 12 months’s sport logs and seemed for 2 issues. First, I seemed for the variety of plate appearances the place there was a runner on first with no runner on second. This excludes the again facet of second-and-third double steals, which aren’t actually what we’re on the lookout for. Subsequent, I seemed for the variety of stolen base makes an attempt in these conditions.
Take these numbers with a grain of salt, as a result of I believe that my methodology will often mess up the denominator when bizarre and uncommon occasions that don’t finish a plate look occur, however the outcomes are fairly clear. The speed at which gamers tried a steal with second base open jumped massively between 2022 and 2023. That got here after a largely static charge for a decade or so; the brand new guidelines made for extra steals, identical to you’d count on. From 2023 to 2024, that charge has declined barely, falling by 20% of the hole between 2022’s and 2023’s charges. In different phrases, baserunners are being much less aggressive when given the identical alternatives.
Perhaps what we’re actually seeing is that 2023 was nearer to equilibrium than anybody anticipated. Baserunners weren’t the one ones who had been attempting out these new guidelines for the primary time – pitchers and catchers had been additionally adapting. Or possibly it’s simply April. The stolen base try charge was truly decrease right now final 12 months than it’s so far in 2024, whereas success charge was meaningfully greater. There’s loads of time for extra information to emerge. The one factor that appears sure, to this point, is that offseason expectations for a massively elevated working sport haven’t come to go.
All statistics on this article are present by means of video games performed on April ninth.
