Let’s take a look at the game’s best and worst performers, as brought to you by WPA (win probability added).
Predictably, Bruce Rondon was the Tigers’ weakest performer while Nicholas Castellanos was their best. On the Red Sox side of things, Chris Young came out on top while Rick Porcello was bringing up the rears. (Honorable mention to reliever Matt Barnes, who was the Sox’s best pitcher in terms of WPA.)
