New York Mets
The Mets designated right-handed reliever Fernando Nieve for assignment after Thursday's 2-0 loss to the Los Angeles Dodgers, paving the way for Manny Acosta to officially be added to the roster.
Nieve was 2-4 with a 6.00 ERA and had allowed 10 homers in 42 innings. He ultimately would need to clear waivers to be sent to Triple-A Buffalo if the Mets go that route.
The Mets originally claimed Nieve off waivers from the Houston Astros on March 13, 2009.
