The Mets promoted RHP Kevin McGowan from Triple-A Las Vegas to replace 2B Neil Walker, who was traded to the Milwaukee Brewers on Saturday.
The 25-year-old reliever will make his major league debut after spending the duration of the season in Triple-A, where he went 5-4 with a 4.06 ERA and had four saves in 44 games. He was drafted by the Mets in the 13th round in 2013 and started his professional career with Single-A Brooklyn.
According to Wayne Randazzo of WOR710, the Mets had been contemplating whether to call him up for some time.
Last season McGowan mostly split time between Single-A St. Lucie and Double-A Binghamton, with one appearance at the Triple-A level, and posted a 2.35 ERA in 42 games overall.
