"I don't know. He's playing catch but I can't say anything," said Guillen of Jenks. "He's pretty far away because he couldn't crank it up. He hasn't even thrown off the mound yet. He's playing catch. The news I have is every time he tries to put something on the ball, he feels a little bit weird."
Jenks has not pitched since closing out both ends of a doubleheader sweep at Fenway Park on Sept. 4. Guillen elected to start Lucas Harrell on Saturday in place of Freddy Garcia, instead of Tony Pena, in order to have Pena ready out of the bullpen.
"If Pena can shut [opponents] down for two innings, I still have a shot to win," Guillen said.
