After three seasons of injuries and assorted disappointments, Jake Peavy and the White Sox start the homestretch of their postseason quest. "Friday night will be all about winning and losing that game," said Peavy, who will start the first of their three-game American League Central showdown against the second-place Tigers in Detroit. "As a player, there's nothing more you can ask for than to play meaningful games and get in the postseason and have a chance at winning the world title."
