Runners Who Make the Least of Their Legs, 2024 Redux

One of my favorite pieces I wrote last year was about players whose baserunning value was at odds with their footspeed: specifically, those who were squandering the God-given advantage of their legs. A year later, I have a new crop of baserunners to write about. We also have an updated version of our metric for calculating baserunning value (BsR) in 2024. So, I decided the topic was worth a fresh look.
I took a pretty subjective approach when I wrote about this last season. I went through the sprint speed leaderboard on Baseball Savant, compared it to our BsR leaderboard, and scanned for players who stood out. This time around, I decided I could be a little more scientific. I made a spreadsheet featuring every player who has taken at least 300 plate appearances and recorded at least 100 competitive runs this season – nice, round, arbitrary cut-off points to limit small sample size randomness. Then, I determined the percentile value for each player’s BsR, as well as the percentile value for two different measurements of speed: sprint speed and the time it takes to run from home plate to first base (HP to 1B).
As I compared the results, three names immediately caught my eye: Jo Adell, Jeff McNeil, and Mickey Moniak. Adell has, by far, the widest gap between his sprint speed percentile (86th) and BsR percentile (9th). That’s approximately a 77% difference; no other runner has a gap bigger than 60%. Meanwhile, McNeil boasts the widest gap between his HP to 1B percentile (86th) and BsR percentile (19th). Finally, Moniak ranks among the top 20% in both sprint speed and HP to 1B, yet he ranks among the bottom third in BsR. He has the third-largest gap between his sprint speed (84th) and BsR (32nd) and the fifth-largest gap between his HP to 1B (83rd) and BsR. He is the only player with one of the five largest gaps in both areas: Read the rest of this entry »
