SAN DIEGO -- Giants catcher Buster Posey was out of Monday night's lineup against the San Diego Padres with a bone bruise in his left thumb.
The injury, which was revealed by an MRI exam on Monday, occurred as Posey applied a tag in last Wednesday's game against Milwaukee. Since then, Posey has mustered one hit in 17 at-bats, dropping his batting average to .311 -- its lowest point since he was hitting .278 on April 8.
Manager Bruce Bochy characterized Posey's playing status as day to day.
"My guess is another day or two [of rest] and he's OK to go," Bochy said.
Posey expressed hope that the rest would "calm down" the discomfort in his thumb, which he said has prevented him from swinging aggressively.
