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."

Jenks will continue to take treatment from the White Sox medical staff and then try to throw a side session on Monday morning.

Jenks, kidding around on Sunday, said he has the record for the highest spring training ERA -- 37.80, thanks to seven earned runs in 1 2/3 innings -- and he doesn't want that record messed with.

White Sox manager Ozzie Guillen said on Saturday that if Jenks isn't ready to pitch during the regular season, he will mix and match the closing role with Matt Thornton and J.J. Putz.
