"The Mets called up righty Manny Acosta from Triple-A Buffalo for the roster spot vacated by demoted lefty Mike O'Connor. Acosta is slated to wear jersey No. 36 and be available for tonight's tilt against the Braves at Citi Field. O'Connor being optioned to Buffalo means that Tim Byrdak is the Mets' only lefty in the bullpen.

The 30-year-old Acosta was 1-0 with four saves and a 1.77 ERA in 20 appearances with Buffalo this year, striking out 27 in 20.1 innings. Opposing hitters were batting .186 against him and he had given up just one run in his last 14.1 innings, a 0.64 ERA.

Last year, Acosta pitched in 41 games for the Mets, going 3-2 with a 2.95 ERA."
