08:12 AM ET 10.17 | Giants ace Matt Cain may or may not have a measure of revenge on his mind when he takes the mound against the Cardinals. The sight of [Cain] and Cardinals left fielder Matt Holliday staring each other down conjures the image of two Wild West gunfighters confronting each other at 20 paces. ... Cain wasn't concerned about the impression he might leave if he flings a pitch that travels a little too far inside toward Holliday. It could be interpreted as retaliation for Holliday's physical Game 2 slide into second baseman Marco Scutaro. "You have to pitch your game," Cain said. "If something gets away from you inside, that's kind of part of the game. You've got to be able to pitch inside and you've got to be able to pitch away."
