LOS ANGELES -- The Mets designated reliever Fernando Nieve for assignment after Thursday's 2-0 loss the Dodgers in Chavez Ravine.
The 28-year-old right-hander was 2-4 with a 6.00 ERA in 42 innings and 40 appearances. He struck out 38 and walked 22. The move was made one day after Nieve gave up the winning run to the D-backs in a 14-inning, 4-3 loss.
The Mets recalled right-hander Manny Acosta from Triple-A Buffalo on Friday. Acosta, 29, went 1-1 with a 3.00 ERA in 12 games with the Mets earlier this year. He was unscored upon in his last seven appearances with the Mets, spanning 6 2/3 innings.
Acosta was 2-3 with five saves and a 3.47 ERA with 36 strikeouts in 28 games with Buffalo.
Nieve was immediately removed from the 40-man roster and the Mets have 10 days to trade or release him. He can be assigned to the Minors if he clears waivers. He was signed to a one-year, $414,000 deal.
