VIDEO: Jack Sock scares Kyrgios during interview at Atlanta Open

The friendship between Jack Sock and Nick Kyrgios is well-documented, as both men have paired together on several occasions at doubles events and are often seen together during tournaments.

Therefore, it came as no surprise when Sock snuck up behind Kyrgios during an interview at the Truist Atlanta Open and scared the Aussie as he was answering a question.

The encounter left Kyrgios clutching his chest, while admitting that he "got so scared" as Sock spooked him mid-sentence, while speaking directly into his ear.
