The real action at a Florida tennis match took place off the court.

As Frances Tiafoe and Mitchell Krueger competed in the Sarasota Open on Tuesday night, their match was interrupted by a couple having sex across the way.

“Well, that is the most bizarre situation,” announcer Mike Cation said on the broadcast. “I don’t know how to put this, folks, but somebody’s phone is going off in the stands … and it was an adult video.”

Cation later confirmed porn wasn’t the culprit.

“Nope, that’s not a phone. That is … that’s an apartment across the lake,” he said. “Well, everyone was looking around to see where that was coming from and finally, figure out, that wasn’t a video. At least somebody’s having a good night.”

While spectators erupted with laughter in the stands, Tiafoe shouted, “It can’t be that good!”

Tiafoe, one of America’s top young talents, won the match in straight sets, 6-3, 6-2.
