Peters was recalled prior to his major-league debut against Philadelphia on Friday, MLB.com's Joe Frisaro reports.
The 25-year-old will make his big-league debut after spending most of this season with Double-A Jacksonville. During nine starts at that level, Peters has posted a 1.97 ERA and 0.97 WHIP to go along with a 40:11 K:BB. Moving forward, the southpaw could remain in the starting rotation for the Marlins throughout the rest of the 2017 campaign.
