Sanchez (shoulder) has been shut down from throwing for at least another month, Jordan McPherson of The Miami Herald reports.
The right-hander has already been optioned to Triple-A Jacksonville and the Marlins are in no hurry to get him back on the mound, so it wouldn't be a surprise if his rest period ends up being even longer. Sanchez underwent shoulder surgery last July and felt discomfort while doing rehab exercises, causing the team to shut him down. The 23-year-old has only thrown 39 innings over the last two seasons, so even if he does finally get healthy over the summer and make it back to the majors, his workload will almost certainly be carefully monitored.
