Matt Cain will start Game 1 of the division series for the Giants later this week.

Cain pitched 21 1/3 innings in the 2010 postseason without allowing an earned run and threw baseball's 22nd perfect game in June.

"I'm excited about it," Cain said. "I want to start my routine tomorrow and get ready for Saturday's game, not try to add anything else to it. I'm going to go through my routine like normal, no matter who we face."
