PHILADELPHIA -- The Marlins won't be adding veteran lefty reliever Joe Beimel to their organization after all. The pending Minor League deal with the 39-year-old has fallen through, according to the Miami Herald.
Beimel, who recently reached an agreement with the Marlins, appeared in 53 games for the Mariners last year, and he was in Spring Training camp with the Rangers before being released on March 23. MLB.com has learned the issue with the Marlins stems from an unspecified medical issue.
Beimel spent time on the disabled list last September with left shoulder inflammation.
The 13-year veteran was initially scheduled to report to extended spring camp with the Marlins as he built up to being game ready.
The Marlins are thin on lefty relief depth.
Prospect Jarlin Garcia is the only southpaw in the bullpen. But the club's No. 3-ranked prospect, according to MLBPipeline.com, is being groomed as a starter, and he isn't regarded as a specialist.

The organization is hopeful Mike Dunn, who has been on the disabled list all season due to a left forearm strain, will be ready in either late May or early June.
At Triple-A New Orleans, lefty options include two players who have already spent time with the Marlins: Cody Ege and Craig Breslow. Chris Narveson made Miami's Opening Day roster as a long reliever. He is also at New Orleans, where he is starting.
Earlier in the season, the Marlins claimed Eric Jokisch, formerly with the Cubs. He is on the 40-man roster and is pitching out of New Orleans' bullpen.
Following Wednesday's 4-2 loss to the Phillies, the Marlins claimed right-hander Cody Hall off waivers from the D-backs and optioned him to Triple-A New Orleans.
