Marlins reunite with reliever in trade with Braves

The Marlins announced that they’ve acquired reliever Michael Petersen from the Braves for cash considerations and optioned him to Triple-A Jacksonville. Miami transferred righty reliever Jesus Tinoco to the 60-day injured list to create a 40-man roster spot. According to the MLB.com transaction log, the Fish also outrighted veteran catcher Rob Brantly to Triple-A after he cleared waivers. Brantly was quietly designated for assignment earlier this week.

Atlanta had designated Petersen for assignment last week. The 31-year-old righty pitched four times for the Braves. He tossed 6 2/3 innings of three-run ball, striking out five with a pair of walks. Petersen has spent more of the season with their top affiliate in Gwinnett. He has turned in a 3.13 ERA with a solid 25.7% strikeout rate and a 7% walk percentage in the minors. It’s his second straight impressive Triple-A season. He fired 33 innings of 1.64 ERA ball while punching out more than a third of opponents there last year.

This will be Petersen’s second stint with Miami. The Fish grabbed him off waivers from the Dodgers last September. Petersen pitched five times, giving up four runs (three earned) through 5 2/3 frames. He was in the major league bullpen for the final two and a half weeks of the season. They lost him on waivers to the Blue Jays at the beginning of the offseason. Petersen subsequently made his way to the Angels and Braves in minor transactions before heading back to Miami.

Petersen stands at 6-foot-7 and averages 97 mph with his fastball. He uses the heater and a low-90s cutter as his two offerings. While he hasn’t missed many bats in his scattered MLB action, he has shown notable strikeout upside in Triple-A. He’s in his second of three option years and has less than one year of MLB service.

Tinoco has been out since June 3 due to a forearm strain. He has yet to begin a minor league rehab assignment, though he has been throwing for the past couple of weeks (via the MLB.com injury tracker). This is a procedural transfer that officially rules him out until the first week of August. Tinoco is multiple weeks away from a return anyway, as he’ll need to progress through bullpen and batting practice sessions before he goes on a rehab stint.

MLB.com’s Christina De Nicola first reported that the Marlins were acquiring Petersen for cash and optioning him.
