Montero, 25, has a 2.45 ERA, 1.04 WHIP and 15:8 K:BB in 18.1 innings (three starts) since being demoted to Double-A Binghamton. He could be an option to make a spot start for the Mets on Saturday against the Rockies.
Admittedly, the Mets would probably prefer to keep Montero in the minor leagues, given the fact he has walked 48 hitters in 98.1 innings between Double-A and Triple-A this season. However, he may be the best option to fill a hole in the schedule created by Monday's postponement and Tuesday's subsequent doubleheader, considering he would be able to start Saturday on normal rest and he is already on the 40-man roster. If Montero does get the call for Saturday's start, it would be wise to avoid him in most formats.
