Jenks held out of Saturday's action

Jenks held out of Saturday's action

GLENDALE, Ariz. -- Bobby Jenks was scratched from Saturday's scheduled relief appearance against the Padres at Camelback Ranch and had a MRI done on his right calf.

The White Sox closer has been bothered by slight irritation in this particular area for much of the spring, having not pitched in a Cactus League game since getting hit hard by the Angels on March 12 in Tempe, Ariz.

Manager Ozzie Guillen doesn't seem to be overly worried about Jenks' physical condition at this point, even with just two weeks remaining in Spring Training.

"Not yet. We have a couple of weeks," said Guillen, after Chicago's 4-1 loss to San Diego on Saturday. "That's why we prevent him from getting hurt worse. That's the reason we [didn't] schedule him.

"He feels a lot better. I talked to him early today and he says it's not that bad. He still feels it when you push. I said to have the MRI. Right now, with the way he sounds, hopefully it goes away in the next couple of days."

Jenks has thrown two side sessions since giving up five runs on four hits in two-thirds of an inning against the Angels. The right-hander deemed both of these efforts as successful.

Even if Jenks continues to be slowed by his calf problem, the same original strain which cost him the last two weeks of the 2009 season, Guillen feels confident about his late-inning crew made up of J.J. Putz, Matt Thornton, Tony Pena and Scott Linebrink.

"Our bullpen is pretty good," Guillen said. "Obviously, if Bobby throws the ball the way he should, if Bobby is ready, our bullpen and our team gets a lot better. But I'm comfortable if Bobby is not there.

"Thornton and J.J. throw the ball good. We have a couple of guys who can fill that role."
