The Mets have placed RHP Robert Gsellman (hamstring) on the 10-day disabled list and recalled INF Matt Reynolds from Triple-A Las Vegas, the team announced prior to Wednesday's game against the Marlins in Miami.
Mets manager Terry Collins said Reynolds was en route from Triple-A Las Vegas and was expected to arrive in time for the game.
Gsellman left Tuesday night's game against the Marlins in the fourth inning after suffering a left hamstring strain while running to first base.
Gsellman was trying to reach base on a grounder and accelerated as he ran down the line, but appeared to hobble before crossing the base. He was then removed from the game.
In three innings of work, Gsellman allowed three runs on five hits and struck out four.
Paul Sewald entered the game in relief.
