Garrett is being brought along slowly in Marlins camp due to soreness in his left shoulder, Jordan McPherson of the Miami Herald reports.
Garrett was still allowed to throw each of the last two days, so there doesn't appear to be any major concern on the team's part. The southpaw collected a 3.66 ERA and 156:29 K:BB across 159.2 innings for Miami last season, making a career-high 30 starts (31 total appearances).
