Giants' Sandoval could miss up to a week

San Francisco Giants third baseman Pablo Sandoval is expected to miss to the team's three-game weekend series with the St. Louis Cardinals.

An MRI on Friday revealed a strained left foot, and the team announced that Sandoval could be out for up to a week.

Over 53 games this season, Sandoval is batting .288 with eight homers and a team-best 37 RBI.
