TUESDAY: The Mets made the move official (on Twitter).

MONDAY: The Mets will designate reliever Manny Acosta for assignment tomorrow, a baseball official told Mike Puma of the New York Post (via Twitter). The move will create roster space for fellow right-hander Chris Schwinden.

Acosta, 31, served up a three-run homer to the Phillies this afternoon to raise his ERA to 11.86 with 9.4 K/9 and 6.1 BB/9. In six big league seasons, Acosta owns a 4.13 ERA with 7.9 K/9 and 4.3 BB/9 for the Mets and Braves.
