The Marlins have designated John Maine for assignment in order to clear a roster spot for Tom Koehler, according to MLB.com's Joe Frisaro (on Twitter).
The 31-year-old Maine tallied 7 1/3 innings for the Fish over the course of four appearances, but the results weren't pretty. The right-hander allowed 10 runs on 15 hits and five walks, leading to a 12.27 ERA. This was Maine's first big league action since 2010 with the Mets. Maine underwent shoulder surgery in May of 2010 and hasn't been able to get his career back on track since. From 2006-08 with the Mets, Maine totaled a 3.93 ERA in 421 innings for the Mets.
