White Sox manager Ozzie Guillen wants the team to make a decision regarding free-agent Jim Thome by Sunday. Guillen doesn't feel pressured to sign Thome, but he wants a decision to be made before he leaves for Miami. "Sometimes, when you [decide] with your heart, you make the wrong decision," the manager said. "Unfortunately in baseball, you have to [decide] with your brains, and I'm going to see what's best for the ballclub." Thome, who was traded from the White Sox to the Dodgers on Aug. 31, is now a free agent.
