Hideki Matsui will be limited to pinch-hitting duties as the World Series shifts to Philadelphia. The Yankees designated hitter hasn't played in the outfield in more than a year because of his troublesome knees. "I can't tell you what my confidence level would be," he told the New York Post through interpreter Roger Kahlon. "My knees are pretty calmed down right now, in that sense I feel pretty good. "I haven't been in the outfield in more than a year. I have to see how I feel once I get out there." Yankees manager Joe Girardi doesn't want to lose Matsui's bat, but admitted that it would be tough to put him out in the field. "As productive as he's been this year, you don't want to lose his bat," said Girardi. "I'm going to watch, see how he moves around and see if we think it's physically possible. "If we can't do it, we'll use him to pinch hit. It might be a situation where you might think about a double switch at high time."
