Sore back slows infielder Sanchez's rehab

SAN FRANCISCO -- Second baseman Freddy Sanchez has encountered yet another physical obstacle in his attempt to return to the Giants' active lineup: a sore lower back.

Manager Bruce Bochy announced the latest "minor setback" for Sanchez, whom he said was likely to undergo an MRI examination perhaps later Monday to determine the extent of the ailment. Bochy did not say when Sanchez might resume participating in extended spring training games.

Bochy said that Sanchez's back actually was bothering him when he checked on the 34-year-old's progress late last week at the Giants' Scottsdale, Ariz., training complex.

"It ended up getting worse," Bochy said.

Sanchez has been striving to complete his recovery from a dislocated right shoulder that required surgery last August. He hasn't played in a regular-season game since he sustained the injury June 10 against Cincinnati. Sanchez's weakened shoulder has prevented him from making the strenuous, cross-body throws on double-play pivots at second base. In an attempted recent adjustment, Sanchez started playing third base in extended spring games in the hopes of playing more frequently and avoiding the pivot throw.
