xERA Is Now on FanGraphs!

We’ve added Statcast’s xERA to our player pages, in the same way we added xwOBA, xBA, and xSLG last week!

xERA uses exit velocity, launch angle, and sprint speed on “topped” or “weakly hit” balls to model what a player’s ERA would look like based on the underlying characteristics of the balls in play.

Additionally, xERA has been added to the player page dashboard, and EV has been replaced with average fastball velocity (vFA).
