White Sox closer Bobby Jenks is done for the season. Jenks pulled his right calf muscle in pregame drills on Tuesday aggravating a previous injury. "I am most likely done for the year," Jenks said. "Today, during the stretch and warmups, I went a little overboard and did a little too much. I completely pulled it." Jenks is eligible for arbitration this winter, which could end his time with the White Sox.
