Jim Thome agreed to a one-year deal with the Phillies on Friday, a source familiar with the negotiations told ESPN.com senior writer Jerry Crasnick. "I'll keep playing," Thome said last month. "I just need teams to call me. I can't go play in the backyard by myself. I don't know the demand for a 41-year-old DH, but my passion is I want to continue to play."
