my guess is gordon will continue to get the same amount of rest he's been getting which is afternoon games after night games. gordon will stay in left, cain will stay in center and dyson/other guy will platoon right.
on the afternoons after a night game, other guy will play left and dyson will stay in right. doesn't sound like they'll move cain from center.
if one of those four gets hurt then you'll see them call up another outfielder and put them ahead of gore. no way gore sees the plate while he's up here.
