Not sure what you’re talking about, but because I got the link to that data I’ve been looking at some of the numbers for today as this marathon passes the 3 1/2 hour mark.
On Brosseau’s double which was ripped into the gap, the stat cast number gives it an XBA of .270. I don’t have to see many things like that to tell me that this stuff can be pretty useless. Maybe it has value to a team’s analytic staff or a player’s agent to evaluate a player’s performance. But used to put more meaning into a game seems ridiculous. We can tell if a ball was hit hard or not, and quantifying with exit velocities, launch angles, and expected BA doesn’t add anything to my reaction to or enjoyment of a game.
