Word out of Angel camp is that Mike Scioscia will split up his two best pitchers in order to start southpaw Joe Saunders at the Stadium. Is he making a smart move? Do lefties actually fare better at Yankee Stadium?
In the limited sample of one season, yes, they do. LHP allowed a batting line of .265/.342/.434. RHP were hit a touch harder in the OBP and SLG categories: .268/.351/.452. That's an OPS difference of .27.
But now the question is whether Jered Weaver is .27 OPSA better than Joe Saunders. He is not.
Saunders' OPSA: .794
Weaver' OPSA: .723
So even subtracting .27 from Saunders' OPSA brings it to .767, still .44 worse than Weaver. Maybe Scioscia is not making the right move by going with the lesser option in game two.
