As announced on the official Twitter account of the New York Mets …
The Mets have acquired LHP Eric O’Flaherty and cash from the Oakland Athletics in exchange for a player to be named later.

Alex Torres was designated for assignment to open a spot on the roster and in the bullpen for the new arrival. O’Flaherty owns an ugly-looking 5.91 ERA in 25 appearances this season, but the 30-year-old has held left-handed batters to a .186/.286/.209 batting line in 2015 and a .201/.266/.263 line for his career. The first-place Mets wanted a true left-handed specialist for the stretch run, and they found one with a crafty waiver trade.
