Montero was recalled from Triple-A Las Vegas on Wednesday, Kristie Ackert of the New York Daily News reports.
On the heels of Tuesday night's pounding at the hands of the Cubs, Montero will return to the majors to provide a fresh arm for the Mets. The right-hander has been pretty terrible during his time in New York this season, however, so it's unlikely that he'll stick around for too long unless he suddenly clicks in the bullpen.
