In the bottom of the first inning against the Arizona Diamondbacks, San Francisco's All-Star catcher Buster Posey was struck in the head by a 94 mile per hour heater.
D-Backs pitcher Taijuan Walker, acquired in a trade with the Seattle Mariners this offseason, had shown spotty control of his fastball through the first three batters. After retiring the side, the Giants faithful let Walker and the rest of the Diamondbacks let their displeasure be known with a loud chorus of boos.
Nick Hundley entered the game as a pinch-runner for Posey but the team does not have an obvious contingency plan if he goes down as well. Trevor Brown is currently on the disabled list and neither Triple-A catcher is on the 40-man roster. Tim Federowicz would be the most likely candidate to fill in if Posey is going to miss some time. Federowicz signed a minor-league deal with the Giants before the season.
After the game, manager Bruce Bochy said of the Giant catcher, "He's doing ok. He'll be reevaluated tomorrow. No hospital visit, no complaints." He added later that the concussion DL is not a forgone conclusion by any means, meaning that the team is hopeful that he may only miss a couple of games. Obviously tomorrow's evaluation will go a long way to determining how long Posey could miss.
Aaron Hill was the emergency catcher if something had happened to Hundley in today's game. As it looks right now, the Giants are hopeful that Posey could be available as the emergency catcher if needed. Bochy said that if Posey wasn't a catcher, he probably would have stayed in, but since there is a chance he could take a foul tip off the mask and therefore be susceptible to further damage, they took him out.
Posey will be at the yard tomorrow night, but in what capacity we still do not know.
