In his WBC notes on his ESPN blog he said that Roger puts icy hot on his garbage and thighs before starts, so that he doesn't get too "comfortable" out on the mound.
I think that this is one of the most bizare things I've ever heard- had anyone else heard this to be the case with him?
Apparently, Jake Peevy did it for the next start and "liked" it as well. A disturbing trend in MLB.
