"He's got a great cutter," Sanchez said with a pain-filled smile about Cubs pitcher Travis Wood.
Sanchez got a standing ovation from the AT&T Park crowd after he stayed in the game and eventually flied out to center.
"If I [had] hit it in the gap, it would have been a single," Sanchez said.
Giants manager Bruce Bochy said Sanchez has a contusion below his knee, and Sanchez said that he didn't need to take X-rays and just iced his leg after the game.
"I just have two knees right now," Sanchez said, pointing to a swollen bump on his leg below the knee.
