Brian Fuentes, who was designated for assignment by the Oakland Athletics last week, has been released by the club.

The left-hander signed a two-year deal with Oakland in 2011 worth $10.5 million, but failed to regain the form that made him an All-Star in 2005, ’06, ’07 and ’09. He recorded a career-high 48 saves for the Angels in 2009.

This season, Fuentes appeared in 26 games, recording five saves in eight opportunities with an ERA of 6.84. On May 2nd, he became the sixth left-hander in MLB history to record 200 career saves.

Ryan Cook is expected to continue getting saves opportunities for the Athletics. The former draft pick of the Diamondbacks has recorded eight saves with a 1.41 ERA, 2.83 FIP and 4.27 xFIP this season.
