Royals, Marlins swap Aaron Crow for Brian Flynn

The Marlins have acquired right-handed reliever Aaron Crow from the Marlins in exchange for left-hander Brian Flynn and right-hander Reid Redman, according to a team announcement. Ken Rosenthal of FOXSports.com was first to report the deal.

Crow, 28, was a part of the Royals' bullpen during their run to the World Series, posting a 6-1 record and 4.12 ERA in 67 appearances. The former setup man was replaced by young guns Kelvin Herrera and Wade Davis in the late innings this season, and the re-signing of Jason Frasor earlier today made him expendable in trade talks. For the Marlins, Crow will likely serve in a middle-inning role in front of Michael Dunn and Steve Cishek.

Flynn, 24, has only made six major league appearances in his career, allowing 24 earned runs in 25 innings of work. He spent the majority of the 2014 season with Triple-A New Orleans, posting a 4.06 ERA in 25 starts. Flynn was the Tigers' seventh round pick in the 2011 draft and was part of the Omar Infante/Anibal Sanchez blockbuster, most recently being ranked by Baseball America as the organization's sixth best prospect after last season.

Redman, 26, was solid in 2014, posting a combined 2.04 ERA in 44 relief appearances split between High-A Jupiter and Double-A Jacksonville. The right-hander was converted to pitching after the 2012 season, and was not considered by MLB.com as one of the team's top 20 prospects at the time of the deal.
