Michael Petersen: Breaking News

Records first save of season

Petersen earned the save Wednesday against the Reds with a scoreless inning, giving up two hits and striking out two. Petersen entered the game with a three-run lead, and while he allowed back-to-back singles to Tyler Stephenson and Noelvi Marte, he ultimately got the job done. Petersen recorded the final out with runners on second and third when he struck out Matt McLain for his first save of the season. The 31-year-old right-hander has a 5.40 ERA and 6:4 K:BB through five innings to begin the season, and he'll revert to lower-leverage usage once closer Pete Fairbanks (personal) returns to the Marlins.

Will begin season in majors

Petersen has claimed a spot in the Marlins' Opening Day bullpen, Christina De Nicola of MLB.com reports. The 31-year-old right-hander did enough this spring to stick around the 26-man roster, producing a 3.12 ERA and 7:3 K:BB over 8.2 Grapefruit League innings. Petersen should handle a low-leverage role after contributing a 4.00 ERA, 1.39 WHIP and 17:7 K:BB in 18 big-league innings last season split between Atlanta and Miami.

Blows save in extras

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. 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.
