UPDATE: The Giants announced that Lincecum was diagnosed with a right forearm contusion.
5:09 p.m. ET: Another high-profile injury to pass along here, as Alex Pavlovic of CSNBayArea.com reports that Giants right-hander Tim Lincecum left today’s start against the Rockies after he was hit in the throwing arm by a comebacker off the bat of D.J. LeMahieu with two outs in the second inning.
Lincecum was in obvious pain and didn’t even attempt to throw a warm-up pitch before walking off the field. He allowed three runs on four hits and two walks before being replaced by Yusmeiro Petit.
Lincecum was struggling even coming into today’s outing and appeared likely to lose his rotation spot with Jake Peavy and Matt Cain slated to come back from the disabled list next week.
