The Mets have called up RHP Seth Lugo from Triple-A Las Vegas, the team announced.
LHP Sean Gilmartin was sent to Triple-A Las Vegas to make room on the roster.
Lugo, 26, is 3-4 with a 6.55 ERA in 19 appearances (13 starts) for Las Vegas this season. He has been in the organization since the Mets drafted him in the 34th round in 2011.
Gilmartin, 26, had allowed seven runs on eight hits in his last two appearances (three innings). He has a 7.00 ERA and 1.56 WHIP this season.
Lugo, who missed the 2012 season due to Spondylolisthesis, which occurs after a displacement of a vertebrae in the spine, went 8-7 with a 3.84 ERA in 24 starts across Double-A Binghamton and Triple-A last season.
He is 28-22 with a 4.26 ERA in 93 games (63 starts) in his minor-league career.
