There is no reason, beyond the deaths of Russell Branyan and Ben Grieve (and I think the game might be cancelled if that happened), that at least ONE of Branyan and Grieve shouldn't be in the lineup.
Ned Yost is a great motivator, gets a great deal out of players that stink, but he is a worse baseball tactician than my dead grandmother.
EDIT:
Thank god Victor Santos gave up 6 runs in the first inning, making it a moot point.
