The Marlins have designated Gil Velazquez for assignment, reports Clark Spencer of The Miami Herald (on Twitter). In related moves, Miami optioned Scott Cousins to Triple-A and activated Emilio Bonifacio and Donnie Murphy off the DL.
Velazquez, 32, had one single in eight plate appearances with the Marlins since being called up earlier this week. The middle infielder hit .314/.392/.383 with three homers in 421 Triple-A appearances before coming up to the show. Velazquez has also seen big league time with the Red Sox and Angels in his career.
