Forever in search of an edge, teams prefer to keep their biomechanical insights private. But some within the game believe this secrecy comes at a cost.

on rates and barrels @DerekVanRiper asked how riley greene could be so good at barreling the ball while being so bad at squaring it up. i was curious too, so i did my best to find out (for @fangraphs):.

Greene is in the 97th percentile in barrel rate and the first percentile in squared-up rate.

interesting probabilities exercise. oddsmakers have pirates at ~28% chance of win in game 1 and ~57% chance of win in game 2. would moving skenes to g1 change their expected wins? seems like it'd be a marginal difference if any .
I follow that we ALL would want to see Skubal vs. Skenes. But if I'm the Pirates, and I want to win a game today, I 100% see the logic of starting Skenes in the other game. You're trading a likely L in G1 for a better chance at a W in G2.

this week joe ryan threw the flattest pitch anyone's homered on this season. it came off the bat of lawrence butler, who hadn't barreled a high fastball his whole career. i broke down how that happened for @fangraphs:.

zach neto is small; he's also hitting lots of homers. the new statcast metrics show how he's doing all that. i wrote about it for @fangraphs:.

Bat speed isn’t the only way to crush a ton of homers.
