Summoned from Triple-A
The Marlins recalled Petersen from Triple-A Jacksonville on Monday.
Analysis
Petersen was acquired from Atlanta in exchange for cash back in July. The 31-year-old right-hander has appeared in 12 games (one start) for Jacksonville since the trade, registering a 6.00 ERA, 1.33 WHIP and 19:5 K:BB across 12 innings. He'll likely be ticketed for low-leverage work out of the Miami bullpen.
