Montero is no longer available to start Wednesday's game against the Dodgers after being used out of the bullpen Monday, Mike Puma of the New York Post reports.
The Mets will now likely turn to Tyler Pill to start Wednesday after Montero notched 3.2 innings in relief Monday. The 26-year-old will continue to serve as a long reliever for the Mets, but he will also remain a spot-start option should another opportunity arise down the road.
