Players took batting practice in puffy pirate shirts. A fan reeled in a slice of marble rye bread with a fishing rod from the suite level. George Costanza announced the third inning. And the first 3,000 attendees at the temporarily renamed Vandelay Industries Park received a Keith Hernandez “Magic Loogie” bobblehead.

All that and more celebrated “25 years of nothing” on Saturday, when, in honor of the debut of “Seinfeld” a quarter century ago, the Brooklyn Cyclones transformed MCU Park in Coney Island into a one-night shrine to one of New York City’s enduring contributions to television comedy.

The communal effort by fans and the Cyclones to send up a show built on the minutia of observational humor kept most of the 8,241-person sellout crowd around through the end of the game, even if it meant watching the Cyclones play their worst game of the season, an 18-2 loss to the Aberdeen IronBirds of Maryland.

The foul poles were renamed the Festivus poles and the information kiosk was repurposed for an “airing of grievances.” There was a low-talker announcer and a close-talker mascot. The Cyclones awarded an actual latex salesman tickets and let a man actually named George Costanza, who drove down from Rhode Island, do radio commentary.
