In a Tweet by by Andy Martino of the New York Daily News, he reports that that Mets have designated right-handed relief pitcher Manny Acosta for assignment.

In addition to Acosta, Pedro Beato, Jason Isringhausen, and Blaine Boyer, had been competing for one (maybe two) spots in the Mets bullpen.  GM Sandy Alderson said that Boyer has made the team and Isringhausen’s fate is still undecided.

In his only season with the Mets in 2010, the 29-year-old was 3-2 with a 2.95 ERA in 41 relief appearances.
