Former Mets star Mike Piazza was spotted watching the Rangers game on his own Wednesday night, blending in with a group of fans.

Piazza parked himself at rooftop bar Rare Bar and Grill at Hilton NY Fashion District, where he was staying with his wife, Alicia Rickter.

Witnesses said Florida resident Piazza, without Alicia, went practically unnoticed, seated on a couch in front of multiple large flat-screens.

He ordered himself a cocktail, awaiting the start of the Stanley Cup Final with other fans.
