The Mets have promoted RHP Tyler Pill to the big-league roster and sent RHP Rafael Montero back to Triple-A to Las Vegas, the team announced prior to Friday's game.
To make room on the 40-man roster for Pill, who wear No. 56 and be available for Friday's game, RHP Seth Lugo was moved to the 60-Day Disabled List.
Pill, who turns 27 on Monday, was 4-1 with a 1.60 ERA in nine combined starts between Triple-A and Double-A this season. He allowed 51 hits, issued 15 walks and struck out 26 batters.
