Watch A.J. Burnett's rosin bag explode into a cloud of dust in his hand
Burnett picked up the rosin bag between innings at PNC Park on Monday, only to find himself covered in a fine white dust. The Pirates starter went on to allow three runs over 5 2/3 innings in a loss to the Cubs, squashing the idea that the mound bags might be filled with some sort of pixie dust.
