Detroit's Carlos Guillen will shift from shortstop to first base next season. Tigers manager Jim Leyland spoke with Guillen about the change on Wednesday. "It's OK," Guillen said before Friday night's game against the White Sox. "I don't have any problems. I want to help this team get better. We were in the World Series last year, and I want to bring us back." Leyland said the team was making the move with Guillen's health in mind.
