I'm confused...I thought they are going to play a doubleheader this coming Monday? Do you mean the Mets saw the weather coming and wanted to play the game this past .Monday?Apparently the Mets were willing to play on Monday and the league (or Braves) shot it down.
Very possible both games get postponed and the Mets won't leave for Milwaukee until Friday. Imagine the Mets having to play a doubleheader on Saturday, leave for Atlanta Sunday evening, play a doubleheader Monday, then fly to San Diego or LA for the wild card round Monday night. Now, that would be insane!
