If the Mets want any chance of making a late push up the NL East standings, they need to start Monday night.

What our Post expert thinks about Mets vs. Phillies

Anything short of a 3-1 series in the Mets’ favor basically wraps up the divison for the Phillies, so you can expect a playoff-like atmosphere at Citizens Bank Ballpark throughout this four-game set.

The Mets will turn to rookie Nolan McLean on Monday night, while the Phillies will counter with struggling veteran righty Aaron Nola.

It’s been a shocking season for the latter, so the Mets could have the upper-hand in the curtain-raiser in the City of Brotherly Love.
