Frances Tiafoe and Mitchell Krueger were playing in the Sarasota Open in Florida when their first round was interrupted by some strange noises across the stadium.
At first, the announcer believes that the sounds are coming from an “adult film” playing on a phone in the stands – but it’s soon clear this isn’t the case.
See what happened here. The players’ – and everyone else’s – reaction is priceless.
A warning: it’s a little risqué.
