The Mets designated reliever Alex Torres for assignment to make room for O'Flaherty on the roster. The A's designated O'Flaherty for assignment on Sunday and he cleared waivers, making him eligible to be traded to New York.
According to ESPN's Adam Rubin, the Mets were seeking a lefty specialist.
In 21 1/3 innings this season, O'Flaherty has a 5.91 ERA and 1.969 WHIP. Left-handed batters are hitting .186 off of O'Flaherty this season, compared to right-handed batters hitting .420. Additionally, O'Flaherty has struck out 13 of the 43 left-handed batters he's faced in 2015.
The Mets recently moved into first place in the NL East after a weekend sweep of the Washington Nationals. After both teams won on Tuesday, New York (57–50) remains one game up in the division.
