Petersen blew the save in Friday's extra-innings victory at Texas. He allowed two runs (one earned) on one hit and no walks over one inning with no strikeouts.

EDGE Analysis

The Miami right-hander blew the save when he conceded a two-run homer to Rowdy Tellez in the 10th to knot the game at 3-3. Petersen was assigned the task of converting his first save because the Marlins' saves leader, Calvin Faucher, had appeared in back-to-back games on Wednesday and Thursday. Petersen is unlikely to receive many future save opportunities and is expected to resume appearing in lower leverage situations. The 31-year-old has pitched to a 4.30 ERA and 1.50 WHIP across 14.2 frames with Atlanta and Miami this season.

The Marlins recalled Petersen from Triple-A Jacksonville on Monday.

EDGE 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.

Atlanta traded Petersen to the Marlins on Wednesday in exchange for cash, Christina De Nicola of MLB.com reports.

EDGE Analysis

Petersen has bounced between Triple-A and MLB this season, giving up three runs in 6.2 innings during his time in the majors.

EDGE Analysis

Petersen will come up from the minors to give Atlanta some extra bullpen depth for the second game of Thursday's twin bill in Philadelphia. He's turned in a 2.45 ERA and 1.62 WHIP across 14.2 Triple-A innings since joining the organization at the start of April, and with AJ Smith-Shawver (elbow) moving to the injured list in a corresponding move, there's room on the active roster for Petersen to remain in Atlanta for a few more days if he performs well.

EDGE Analysis

Petersen's stay with the big club lasted all of one day, with the right-hander not getting called upon in relief in Monday's 7-6 win over the Cardinals. He'll cede his spot on the 26-man active roster to right-hander Nathan Wiles, who was called up from Triple-A and is expected to work in bulk relief during Tuesday's game.

EDGE Analysis

Petersen will take the spot on the 26-man roster vacated by Spencer Strider (hamstring), who was placed on the 15-day injured list in a corresponding move.
