Zimmermann, Flores on mend

CHICAGO -- It appears right-hander Jordan Zimmermann and catcher Jesus Flores could be back on the field soon.

Zimmermann, who is on the disabled list because of right elbow reconstruction, is throwing live batting practice. General manager Mike Rizzo said Zimmermann is ahead of schedule, but he isn't expected to participate in a rehab assignment until sometime in August.

Catcher Jesus Flores, on the DL with a right shoulder injury, is swinging the bat, but Rizzo didn't give a timetable when he will return to action.
