The Marlins have designated righty Arquimedes Caminero for assignment, according to the MLB.com transactions page. Caminero, 27, has been in the Miami organization since the then-Florida Marlins signed him out of the Dominican Republic back in 2005.
Caminero has had some ups and downs in only two brief MLB stints. In 2013, he worked to a 2.77 ERA over 13 frames, but last year he was torched for eight earned runs in just 6 2/3 innings.
Caminero has had no trouble missing bats at all levels, averaging 11.0 K/9 over nine minor league campaigns and whiffing better than a batter an inning in the bigs. He has struggled somewhat with the free pass (4.5 BB/9 in the minors), but his mid-90s fastball will surely draw some interest from other organizations.
