Night tennis began at the United States Open in 1975 with certain stars trying to beg out and certain patrons trying to dump unwanted tickets on scalpers.

But the new breed of player considers night tennis an honor. Showtime.

Some of the longest and noisiest matches at the Open — in tennis history — have been played when the werewolves of Wall Street took the limo out to Queens, drinking their $14 special Open cocktails and howling into the night.

“I mean, it’s the most electric atmosphere in our sport,” Andy Roddick said Thursday while announcing his retirement after this Open.

Roddick had been slotted for a Friday night match — because he deserved it for having won his lone Grand Slam title here in 2003. On the start of the Labor Day weekend, he brought his star power to the night program.
