Jenks done for the 2009 season

Bobby Jenks is done for the year after suffering a pulled right calf muscle during pregame workouts at U. S. Cellular Field on Tuesday.

“I heard the pop, felt it and it’s not good,” said Jenks, after the White Sox dropped an 8-6 decision to the Twins. “It’s unfortunate with the timing with everything, the way our team has been going. All together, it’s one (bad) deal.”

The White Sox closer explained how he had a slight strain of the same area in Seattle last week. But the extra effort given on Tuesday pushed the injury too far.

“During stretch and warm-ups, I went a little overboard and did a little too much,” Jenks said. “I guess I wasn’t happy with the slight strain. I had to do it all the way.”
