The 22-year-old Pie doubled off legend Greg Maddux in the fifth inning and threw out Russell Branyan at the plate in the 10th inning to get the Wrigley Field crowd going.
Soriano said that he would consider moving to left field and allow Pie to play center if the rookie continues to play well.
"Whatever the manager (Lou Piniella) wants to do with us. ... I played left field last year," Soriano said. "All three outfield positions are the same. You have to catch the ball. Any position Lou wants me to play is OK. Felix is a special kid. He's a very good athlete and a very good player."
