ATLANTA -- Hector Sanchez's sprained left knee forced him to the 15-day disabled list Wednesday, dashing the cautious optimism the Giants expressed one night earlier when the rookie catcher was injured.San Francisco recalled catcher Eli Whiteside from Triple-A Fresno to replace Sanchez on the active roster. Sanchez said after Tuesday's 9-0 victory over Atlanta that, at best, he might be sidelined for only a couple of days, a sentiment that manager Bruce Bochy echoed. But the MRI that Sanchez underwent Wednesday morning indicated that he could be sidelined for at least five to seven days, prompting the Giants to act. "It's a tough call, because you don't know when Hector will be ready," Bochy said. "... Plus, you don't want this [injury] to linger all year." Sanchez, who has established himself as a capable backup for Buster Posey, won't need surgery and believes that he'll physically be able to resume playing when he becomes eligible for activation on Aug. 2. "I feel good because it's nothing bad," said Sanchez, who's batting .281 with two home runs and 24 RBIs in 39 games. Sanchez hurt himself as he returned to first base during Tuesday's fourth inning. Whiteside has spent all or part of the previous three seasons with the Giants, hitting .233 in 187 games through that span. More importantly, he's familiar with the Giants' pitchers. He was batting .241 with one home run and 15 RBIs in 47 games for Fresno.
