The Mets claimed Weston off waivers from the Orioles on Thursday and optioned him to Triple-A Syracuse.
Weston pitched a scoreless inning during his MLB debut back in May but owns a 7.89 ERA and 1.94 WHIP through 51.1 frames in the minors. The Mets will add the 26-year-old to their 40-man roster despite his poor performance and keep him at Triple-A, where he is likely to remain for the remainder of the season. Shawn Ross was designated for assignment in a corresponding move.
