Cautious Giants have Posey serve as DH

Cautious Giants have Posey serve as DH

CHICAGO -- Buster Posey felt well enough to catch Tuesday's series opener for the Giants, but was limited to designated-hitter duties as a precaution.

"I'm all good," Posey said, using both hands to flash the universal thumbs-up gesture for optimism.

Giants manager Bruce Bochy agreed that Posey, who left Sunday's game against Colorado early after being rocked by a foul tip off his facemask, could have caught against the White Sox. But Bochy said that using Posey strictly as a DH "was my call. I wanted him to get an extra day [off] in case he takes a shot off the mask."

Bochy said Michael Morse will replace Posey as the Giants' DH for Wednesday's series finale. That would give Morse essentially two days of rest, since Thursday is a scheduled off-day.
