My two cents would be:
(1) According to Fangraphs, RJ had a poor year all around in 2009 (so all pitch types have lousy values) but
(2) Relative to his own performances, he had an easier time with non-fastballs... it was the heat that he had trouble dealing with...
(3) My guess is that RJ, a transitioning AAA player after all, simply came up against an overwhelming pitch (Brett Anderson's hook) and couldn't deal...
