Giants' Posey struck in head by pitch, leaves game

SAN FRANCISCO (AP) Buster Posey was doing well and examined for a concussion after he was struck in the helmet during the first inning of San Francisco's 4-1 home-opening win Monday when hit by a 94 mph fastball from Arizona starter Taijuan Walker.

Posey will be re-evaluated Tuesday but, ''He's doing good, he's doing fine,'' manager Bruce Bochy said.

Posey was struck by an 0-1 pitch with two out in the first and immediately went down. Athletic trainer Dave Groeschner sprinted toward the plate and Bochy was right behind. Posey got up on his own but exited the game, with Nick Hundley entering to pinch run and stay in the game as catcher.

Walker was booed at the conclusion of the inning and every time out thereafter.
