Mets acquire Eric O'Flaherty from Athletics

New York is still not done adding pieces to its major league roster. The Mets announced they acquired reliever Eric O'Flaherty from the Athletics in exchange for cash considerations and a player to be named later on Tuesday night.

Alex Torres was designated for assignment in order to make room for O'Flaherty on the active roster.

Oakland opted to designate O'Flaherty for assignment over the weekend in order to clear a roster spot for the newly acquired Aaron Brooks.

O'Flaherty, 30, had a notable amount of success in 2014, his first year returning from Tommy John surgery. He posted a 2.25 ERA over 20 innings but has struggled in 2015. Over 21.1 innings with Oakland this season, O'Flaherty has pitched to a 5.91 ERA and 4.12 FIP. He is in the second year of a two-year, $7 million deal he signed with the Braves before the start of 2014.

While O'Flaherty is due $1.86 million through the end of the season, the Athletics are expected to pick up at least a portion of his remaining salary. O'Flaherty joins Tyler Clippard, who was sent from Oakland to New York before the July 31 non-waiver trade deadline, in the Mets' bullpen.

Although Torres pitched to a 3.15 ERA over 34.1 innings before being designated, he has walked 26 batters. Left-handed hitters have also had a notable amount of success against Torres (.268 average), who was acquired by the Mets last spring.

If he is placed on outright waivers, a club seeking left-handed depth might consider adding Torres. However, if not, the Mets will have the opportunity to option him to Triple-A, where he can work on improving his command.
