Garrett was recalled from Triple-A Jacksonville ahead of Thursday's start against the Mets, Christina De Nicola of MLB.com reports.
Garrett allowed two runs on four hits and a walk while striking out 10 in seven innings during his most recent major-league start July 24, but he was still sent down following the outing. If he performs well Thursday, the southpaw should have the chance to remain in the rotation since Trevor Rogers (personal), Pablo Lopez (shoulder) and Cody Poteet (knee) are all sidelined.
