If Tuesday’s loss didn’t effectively end the Mets season, then the out-of-town scoreboard may signal the dagger.

It showed the Cubs beating the Mariners, 6-1, which combined with the Mets’ epic 11-10 loss to the Nationals, puts the not-so-‘Amazins five games out of the wild-card entering Wednesday.

Three teams — the Brewers, Diamondbacks and Phillies — stand between the Mets and the wild-card Cubs and Nationals.

With 24 games remaining, it will take a Mets miracle to get into the postseason.
