NEW YORK (CBSNewYork) — The Mets have no shortage of celebrity fans — see Jerry Seinfeld, Chris Rock, Kevin James and Bill Maher — but the one with the most team spirit is likely Jim Breuer.

The stand-up comedian and former “Saturday Night Live” star has been documenting New York’s season on Facebook, and on Monday night he joined The 7 Line Army in Baltimore for the series opener against the Orioles.

Breuer joined the superfans on a bus to Camden Yards.

Jacob deGrom was brilliant yet again for the Amazin’s, but things got dicey in the ninth inning. The Orioles scored twice to make it 5-3 before closer Jeurys Familia got Manny Machado to ground out to third base for the final out.

The 7 Line Army got a shout-out from Mets legend Mike Piazza on Twitter and Curtis Granderson after his two-home-run performance.

Manager Terry Collins was also impressed.

“It’s electric,” the skipper said. “Our fans, they’re incredible. Wherever we go, we had them in Florida. The 7 Line was here tonight, they’re unbelievable when they show up. “You’ve gotta like it. If you’re a player, my gosh almighty. How can you feel tired or fatigued when you’ve got that atmosphere going? It’s really cool.”

The Mets will look to sweep the quick two-game set on Wednesday night. Noah Syndergaard will get the ball for New York.
