The team also activated Steven Matz, Bobby Parnell and Erik Goeddel from the disabled list.
The Mets now have 32 players on the roster, and can expand to 40 players if they so choose.
To make room on the 40-man roster, Vic Black and Danny Muno were outrighted. Both players cleared waivers and were sent back to Triple-A Las Vegas.
Black has dealt with a shoulder injury this year and struggled for Triple-A Las Vegas, posting a 7.94 ERA while walking 24 batters in 22 2/3 innings.
