Posey shifts to first base for mild respite

Posey shifts to first base for mild respite

PHOENIX -- The Giants' previous five games averaged three hours and 25 minutes, partly explaining Buster Posey's start at first base on Saturday against Arizona.

Posey has started 24 games at first, compared with 101 at catcher. During the aforementioned five-game stretch, Posey caught four and played first base once. So Bochy maintained his habit of moving Posey to the infield to break up the grueling monotony.

Bochy noted that he intends to use Posey behind the plate in Sunday's series finale, which also factored in Saturday's switch.

"He'll tell you [playing first] is a little bit of a break," Bochy said. "We've played some long games -- that's my fault, I guess," he added, referring to his multiple pitching changes.

Posey was cognizant of the recent spate of prolonged games. "If the game ends by 8:30, I'll be happy," Posey jokingly said before batting practice. The first pitch was thrown at 5:10 p.m. PT.
