The Mets acquired Seelinger from the Tigers on Monday in exchange for cash consideration, Mike Puma of the New York Post reports.
Seelinger has turned in a 3.89 ERA and 49:19 K:BB over 39.1 innings this season at Triple-A Toledo. The 31-year-old reliever has not yet pitched at the major-league level but has consistently piled up lots of strikeouts in the minors, boasting a career 31.8 percent strikeout rate on the farm.
