The Mets claimed reliever Manny Acosta off waivers from the Braves, tweets MLB.com's Mark Bowman. Acosta, 29 in May, posted a 4.34 ERA, 7.7 K/9, and 4.6 BB/9 in 37.3 innings for the Braves last year. He was better in his 27.3 minor league innings, but walked too many there as well.
Acosta throws a mid-90s fastball and racked up groundballs in his better years. He even served as the Braves' closer in early '08 when Rafael Soriano went down. Hamstring and shoulder injuries cut that season short, however. The Mets snagged a quality arm from their division rivals, but now they must help his stuff translate to results.
