It hit him in his non-throwing hand and knocked his glove off (looked like it hit the padded part of his hand). He threw a couple of warm-up pitches and got the final out of the inning. Tom McCarthy said he has a "hand contusion."
David Herndon came in to replace him. I started typing this when Hamels came out of the game, there are now two outs… with two men on base and one run already scored. Herndon!
X-rays on his hand were negative, according to the Phillies. He's listed as day-to-day and scheduled to make his next start.
