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.
