You are correct, however:
04/10 Vs vs Tor:
Young starts vs Estrada (I assume the train of thought is that he has similar splits vs righties and lefties). 7th inning, 2-0 game, Estrada in his last inning. Shaw walks, and Young is allowed to his against Estrada and predictably fails with Holt and Panda on the bench and Storen warming up.
17/04 vs Toronto:
Young starts vs Sanchez. 9th inning. Hanley singles, Shaw homers, Young K's against Osuna, who is very tough on righties, with Holt on the bench. Sox lose 5-3.
Couple games later starts against another righty (Fiers), in a loss to Hou. I assume it's because Fiers has a slight reverse split. But Young is coming off a sub -600 OPS season against righties.
I mean, I have clearly admitted the usage patterns have improved (no longer pinch hitting for Shaw, limiting exposure for righties) but that doesn't make it impossible to admit he handled Young crappily in the beginning of the season for the sake of "getting him AB's".
