Looks like he was pulled because his pitches were getting up there, he looked gassed and he had a couple of running-over-to-cover-1B plays (yes! he did cover 1B!). They did look at his hand and as he walked in the dugout, he was holding his hand oddly, like a claw. Len and Bob were speculating that he probably had some hand/forearm cramping because of the heat/humidity. No indication from either of them that there's concern over something more serious.
