The Mets are still riding the "Grimace effect" into Game 3 of the NLDS, with the city decorating one of the subway lines with Grimace decals and the McDonald's character making a surprise appearance.

Mets fans on the 7-line train ahead of Tuesday’s third NLDS game against the Philadelphia Phillies were greeted by Grimace — the team’s good-luck mascot adopted from McDonald’s. The purple character’s face was also plastered across the coincidentally purple train’s 10 cars — including one decal of Grimace sporting an iconic blue Mets cap.
