The Marlins designated righty Jay Buente for assignment to open a spot on the 25-man roster for Steve Cishek, tweets Joe Capozzi of the Palm Beach Post. The move leaves the Marlins with 39 players on the 40-man roster.
Buente, 27, posted a 1.94 ERA, 9.5 K/9, 2.2 BB/9, and 0.2 HR/9 in 41 2/3 Triple-A innings this year, including five starts. He spent most of 2010 in relief, posting a 10.0 K/9 across three levels. Buente was a fifth-round pick of the Marlins in 2007.
