Young American Frances Tiafoe was taking on countryman Mitchell Krueger in a first-round match at a tournament on the second-tier ATP Challenger Tour overnight.
Tiafoe was preparing to serve midway through the second set when he paused due to some, um, noise emanating from a neighbouring apartment complex.
A woman’s loud moaning was echoing across the court, completely distracting both players.
It continued for a few of minutes with Tiafoe yelling out: “It can’t be that good.”
Commentator Mike Cation thought the noise was coming from someone’s phone before realising his mistake.
“No, that’s not a phone, that’s an apartment across the lake,” he said. “Oh my God.”
