DENVER — The Mets dropped a 5-2 decision to the Rockies on Wednesday, but a bigger concern still lingered from the night before: Mike Pelfrey. The organization’s alarm level with the big right-hander is high as Pelfrey completes what he admits is “a terrible year.”

Colleague Brian Lewis has more on Carlos Beltran‘s first minor-league rehab appearance Wednesday night in Brooklyn.

In the notes, John Maine is another Met firmly on the comeback trail.
