Mets purchased the contract of RHP Manny Acosta from Triple-A Buffalo. Acosta was booted off the 40-man roster in late May, but he's back up with the big club after posting a 2.25 ERA and 25/4 K/BB ratio over 28 innings at the Triple-A level. The Mets have yet to announce a corresponding roster move, but outfielder Lucas Duda could be hours away from a demotion.
