3 things you didn’t know about all the SB in 2023

If you want stolen bases, then you need to completely love the brand new guidelines which have come to Major League Baseball in 2023. The new tips have been particularly meant to encourage athleticism and motion on the bases, and so they’ve executed precisely that.

But it’s not likely about stolen-base makes an attempt, at the least not from a historic standpoint.

While steal tries are certainly up over current years, they don’t actually stand out meaningfully traditionally. Through Sunday, we’ve seen 1.7 makes an attempt per staff sport, which is greater than final yr’s 1.4, but much like 2010, or 2000, or 1973, or 1937, admittedly cherry-picked years which additionally had comparable charges of makes an attempt per sport. If the objective was to extend makes an attempt over the current lows of the twenty first century, then mission completed. But 1.7 makes an attempt per staff sport is kind of the identical because the since-World-War-II common of … 1.6.

Instead, the story is de facto about success price. Of the primary 241 steal makes an attempt this season, 196 have been profitable, an 81% price. If that sounds excessive, it’s. It’s an all-time excessive. We’re not seeing probably the most profitable steals per sport ever, as a result of we’re simply not seeing the extent of makes an attempt we did a long time in the past. But when a steal is tried, by no means in recorded baseball historical past has it been extra prone to be a hit.

We know the surroundings is totally different. We know the bases are barely bigger. We know the pitchers are restricted in how typically they’ll throw over to first base. So what’s really occurring right here to trigger the modifications we’re seeing? It won’t be what you assume.

All information is updated by means of Sunday’s video games.

1) Yes, success price is up
… however it was already excessive!

If we are saying “it’s an all-time high,” we’d higher present that. That 81% success price this yr could be the best in baseball historical past (which we’re beginning in 1951, when the caught stealing first started to be reliably tracked). The bounce there may be clear. We’ve by no means seen it above 76%, and now, in 2023, we’re above 80%.

But whereas there’s an apparent leap over 2022, this bounce considerably obscures the truth that the second-best steal price in baseball historical past was in ’21, and the third-best was in ’22, and the fourth-best was in ’20, and actually, every of the highest 16 seasons have come since 2006. Stolen-base makes an attempt had been down for a very long time, but steal success had been up anyway.

Why? As MLB.com’s Senior Data Analyst Tom Tango not too long ago confirmed, for years earlier than any of those new guidelines got here into impact, groups have been simply getting smarter at choosing their spots to steal, which means they have been getting higher and higher at avoiding the spots the place they have been much less prone to succeed. “In 2016,” Tango wrote, “runners had an expected SB% of 75%+ almost half the time, while they had an expected SB% under 60% over one-quarter of the time. Runners were far too aggressive. But over the years, runners are getting smarter. And in 2022, they were at their smartest.”

So the brand new guidelines have had an impact, to make sure. But that stated, at the least a part of the development was already in movement.

2) Steals are up at second base, type of
But it actually, actually issues when.

Let’s focus simply on steals at second base. The success price is up, although in all probability not in a manner that’s simply noticeable to the bare eye. Is 79% greater than 75%? Sure. Could you have got stated there are loads extra profitable steals at second should you didn’t have that quantity helpful? Maybe not. It’s all of 1 additional profitable steal each 25 makes an attempt.

But there’s a brand new wrinkle this yr, and it’s the time period disengagement.

A “disengagement,” in baseball parlance, means both a step-off or a pickoff try with a runner on base. Pitchers can use it both to reset the pitch timer or attempt to nab a runner, however no matter they’re doing, they’ll solely freely do it twice. If they struggle it a 3rd time in a plate look, it comes with additional threat: Successfully get the runner out, or endure the implications of a balk. Pickoffs have mattered, even after they didn’t result in an out; in 2015, Baseball Prospectus’s Russell Carleton estimated {that a} pickoff throw would lower the success price of an ensuing stolen-base try by 12 proportion factors.

So let’s take that very same chart above, and look solely at steal makes an attempt on zero disengagements. Guess what? Steal success is definitely down.

If that’s true, then it should even be true that success price after one or two disengagements have to be greater than they’re on zero, and it actually, actually is. It is basically the whole thing of the uptick in stolen-base successes.

All of which appears to imply that disengagements are invaluable foreign money, and in that case, drawing them may be a ability. It may be too early to say that some groups are prioritizing this the place others are usually not — absolutely this has greater than just a little to do with the identification of the runners on base and the way typically a staff even will get on base — however while you see the Guardians, Astros and Dodgers on the prime of this checklist, possibly it’s not too early.

Cleveland teammates Myles Straw (10) and Steven Kwan (9) are on the prime of the person leaderboard right here, simply forward of Trea Turner (8).

3) Steals are wildly up at third base.
It took till Tuesday for a catcher to catch a runner making an attempt to steal third!

Third base, nonetheless, is a distinct story fully.

Until Arizona’s Gabriel Moreno caught Milwaukee’s Joey Wiemer making an attempt to take third base on Tuesday night time, there had been 28 listed stolen base makes an attempt at third base, and precisely zero instances {that a} catcher had prevented the runner from advancing. (Before Moreno, the one time a runner failed to succeed in third was on a play that did not even require the companies of the catcher — it was a pickoff play by Washington’s Kyle Finnegan, a pitcher.)

This one is especially fascinating, as a result of stolen-base charges at third base had been regular for years — it was 77% final yr, and 77% in 2008, and 77% from 2008-22, with minor deviations. But now, instantly it’s 93%, together with the Finnegan pickoff, or 97% with out. What’s occurring right here? The view of Starling Marte’s stolen base right here gives a clue:

Or the look of defeat on the face of J.T. Realmuto, universally considered baseball’s greatest baserunner-defeating catcher weapon, when he realized it wasn’t even value his effort to attempt to make a throw to catch Gleyber Torres.

Or how Ryan McMahon was 49 ft off of second base on his method to third when Domingo Tapia acquired round to creating his pitch, taking a throw try fully off the desk.

Or the sheer size of time you will want to observe this clip earlier than you even understand {that a} runner was on second in any respect, as a result of Eli Morgan definitely wasn’t worrying about Conner Capel taking third — though Capel represented the game-winning run within the backside of the ninth:

While McMahon’s instance is a very egregious one, each one of many steals of third up to now this yr have had a lead distance (on the time of pitch launch) of at the least 26 ft, with most being over 30, and the typical being 33 ft. It’s almost two ft greater than what it was on 2022’s makes an attempt of third base, and if two ft doesn’t sound like a lot, understand that two ft was additionally the distinction between the typical lead distance (at time of pitch launch) between a profitable steal (32 ft) and a failed one (30 ft).

That, it appears to clarify, is much more about how pitchers are dealing with the brand new guidelines, and so much much less concerning the bigger bases subtracting just a few inches between the baggage. Which additionally implies that it is early, and that finally pitchers will regulate, and in some unspecified time in the future — in all probability — some catcher goes to throw out some runner stealing third base.

So how did Moreno do it? It helps that he acquired the ball down to 3rd in a lightning-quick 1.46 seconds, however it’s additionally that Wiemer, who had simply stolen second base off Moreno and pitcher Merrill Kelly, had a secondary lead of solely 26 ft when the pitch was launched, on the very low finish of the lead distances we simply talked about. It was by no means going to be a 100% success price at third all yr, in fact. But if pitchers can not help out their catchers just a little extra, it may be a a lot simpler time stealing third than we have seen in years — or, maybe, ever.
