The Giants defeated the Reds 3-2 thanks to a walk-off win on Friday night, but it was tempered by an injury to infielder Freddy Sanchez. Sanchez dislocated his shoulder and will undergo further tests to determine the severity of the injury and how long he'll be out. "We have to keep fighting and moving forward," said Andres Torres. "That's how we did it last year, too. Freddy's a big part of us but we have to move on." Sanchez made a backhand grab of Brandon Phillips' sharp grounder up the middle in the fifth but used his right hand to brace himself as he slid on the edge of the outfield grass. Sanchez, who underwent surgery on his left shoulder in December, sat on his knees and flicked the ball away with his glove hand as manager Bruce Bochy and assistant athletic trainer Mark Gruesbeck rushed out from the dugout. Sanchez was later helped up and walked off the field but with his right arm held up by Gruesbeck. Bochy said Sanchez will undergo an MRI test soon. "I can't tell you how long or how serious (it is)," Bochy said. "That's a lot, what we're taking right now. They'll keep grinding and moving forward. There's not much else you can do. We feel horrible for Freddy, a great player we'll certainly miss, but we'll move on."
