Giants catcher Buster Posey was in the starting lineup at first base Thursday against the Marlins after leaving Wednesday's game due to a head injury.

Posey left Wednesday's game after taking a foul ball of his facemask. Manager Bruce Bochy said Posey came out of the game because he was feeling "off". He did pass a concussion test after leaving the game.

Posey enters play Thursday riding a seven-game hit streak. He is batting .462 (12 for 26) with two home runs, four doubles, 13 RBI and eight runs in that span.
