Zych (shoulder) isn't likely to return to active duty before mid-June at the earliest, the News Tribune reports.
The right-hander had been given a four-week timetable when he was placed on the disabled list with tendinitis in his rotator cuff May 3, but that gets pushed back by about 10 days. Zych has started to play catch on flat ground, but hasn't yet progressed to throwing from a mound.
