The Marlins announced today that they have designated right-hander Vin Mazzaro for assignment. The move creates space on the roster for fellow righty Jarred Cosart to be activated from the disabled list.
Mazzaro, 28, was a key member of the Pirates’ bullpen in 2013, working to a 2.81 ERA with 5.6 K/9 and 2.6 BB/9 in 73 2/3 innings that season, but he still found himself as the odd man out the following Spring Training as an out-of-options reliever with a marginal strikeout rate. Many expected him to be traded or claimed off waivers after being designated for assignment, but Mazzaro cleared and accepted an outright assignment to Triple-A.
