The Mets have designated Aaron Laffey for assignment, according to Marc Carig of Newsday (on Twitter). The left-hander saw less than an inning of work against the Nationals last night as he allowed a walk and a double to set up a three-run homer from Adam LaRoche.
Laffey, 28, signed a minor league deal with the Mets in December. The veteran pitched to a 4.56 ERA with 4.3 K/9 and 3.3 BB/9 in 16 starts and six relief appearances for the Blue Jays last season. He also made eleven starts for Triple-A Las Vegas, posting a 4.52 ERA with 5.4 K/9 and 2.8 BB/9.
