Mets sent RHP Manny Acosta outright to Triple-A Buffalo. As expected, Acosta cleared waivers. The 31-year-old right-hander was a solid contributor for the Mets' bullpen from 2010-2011, but he has a miserable 11.86 ERA and 23/15 K/BB ratio over 22 innings this season. We'll probably see him again later this summer.
