DETROIT — When the Giants were forced to go seven games in the National League Championship Series, that pushed ace righthander Matt Cain back to Game 4 of the World Series. When San Francisco won the first two games of the Series, that turned a potential problem into a positive.

“I was going to take the ball whenever they wanted me to take it, and that’s always been my way,” Cain said on Saturday before the Giants won Game 3, 2-0. “Whenever they want me to pitch, I’m going to take it. Take the ball, and go out there and try to find a way to win.”
