An MRI on Bobby Jenks' right calf revealed inflammation but no structural damage, and the Chicago White Sox closer will try to pitch through the injury. "That's the odd part of the injury," Jenks said on Sunday. "They say it can't get any worse. It's like you have a sore arm and you're working through it." Jenks said he is OK when he is throwing the ball, but he feels some discomfort when he tries to pivot after delivering a pitch in order to field a ground ball or cover first base. "I irritated it the day I was supposed to throw," Jenks said. "As for the results of the MRI, it turns out it's a good report. There is some irritation in there but it's not structural damage."
