The Marlins recalled Garrett from Triple-A Jacksonville on Saturday, Jordan McPherson of the Miami Herald reports.
The lefty rejoins Miami to fill the roster spot of Trevor Rogers (back) and presumably enter the starting rotation until Rogers is activated. In four appearances with the Marlins this season, three of which were starts, Garrett has pitched 15.2 innings and posted a 5.17 ERA. Walks have been an issue for him, though, as he's issued eight free passes.
