Giants catcher Buster Posey struck in head by pitch in win (Yahoo Sports)

Giants catcher Buster Posey was struck in the helmet by a 94 mph fastball in the first inning and forced out of the game, a frightening moment in San Francisco's 4-1 victory Monday against the Arizona Diamondbacks in its home opener. Taijuan Walker's 0-1 fastball with two out in the first inning sent the Gold Glove catcher immediately to ground. Athletic trainer Dave Groeschner sprinted toward the plate and manager Bruce Bochy was right behind.
