The Runners Who Make the Least of Their Legs

Carlos Correa seems like he should be a good baserunner. He’s a young shortstop with great instincts in the field. He’s tall and lean, with a long pair of legs. In his rookie season, he stole 32 bases in 37 attempts across Double-A, Triple-A, and the majors. Yet despite what you’d think, Correa is decidedly not a good baserunner. In fact, he’s been the least valuable runner in the game this season. Over the past two years, he has been worth -13.6 baserunning runs (BsR); only Christian Vázquez (-14.0 BsR) has been worse. Surrounded by catchers, first basemen, and aging veterans, Correa is a fish out of water at the bottom of the BsR leaderboards.
The Twins shortstop recently opened up about his baserunning to Do-Hyoung Park of MLB.com, calling himself “slow as f–k.” It’s no surprise Correa is down on himself amid a career-worst season. Moreover, in a textual medium, it’s hard to gauge just how tongue-in-cheek his comment was. Still, whether he was dramatizing, joking, or a bit of both, it’s worth clarifying that Correa isn’t quite that slow. His sprint speed, as measured by Statcast, ranks in the 34th percentile – slow, sure, but it’s not like he’s walking around the bases. There are 177 players with a slower sprint speed this season (min. 10 opportunities) and 115 with a slower home-to-first time. If Correa is “slow as f–k,” I don’t even want to know what expletives he’d use to describe Miguel Cabrera and Yasmani Grandal. Correa may not have much speed to work with, but even so, his problem is that he isn’t making the most of the speed he’s got.
Correa isn’t the only player guilty of squandering speed, either. Indeed, there are much faster players who have hurt their teams on the basepaths this season, guys who can’t rely on the “slow as f–k” defense. Inspired by Correa’s comments, I looked at the sprint speed for the 50 worst players by BsR this season and took note of some interesting names. I also conducted my search the other way around, checking out the BsR for each of the 50 fastest runners by sprint speed. These are the guys who stood out. Read the rest of this entry »
