Derek Holland has criticized the San Francisco Giants' front office and says he faked the injury that led to a stint on the injured list.

Holland was demoted to the bullpen on Saturday night and said he has "no idea what they're doing" in the front office.

The lefty gave up seven runs in 2 2/3 innings Thursday during a 12-11 loss to the Colorado Rockies, his first outing after going on the IL because of a left index finger bone bruise.
