Corentin Moutet's ringing phone interrupts his Rome match with Novak Djokovic

The call is coming from inside the house ... or in this case, Corentin Moutet's tennis bag. In a hilarious scene at the Internazionali BNL d'Italia on Friday, the Frenchman's ringing phone interrupted action early in the second set of his second-round match against world No. 1 Novak Djokovic.

With the score finely poised at deuce in the first game of the second set, play was interrupted as all present on Campo Centrale searched for the source of the sound. Quickly, the 25-year-old lucky loser, who only going into the main draw when his countryman Arthur Cazaux withdrew, realized it belonged to him as the crowd roared with laughter.

Grins abounded, not the least of which from Moutet, Djokovic and umpire Carlos Bernardes, as he quickly sprinted to his bench to silence the phone (though not before eliciting more belly laughs from the fans by pretending to answer it) and play soon continued.

Djokovic took the interruption in stride between the lines, too. After winning five straight games to take the first set, he lost just one game in the second set of the 6-3, 6-1 win.

"Corentin is a very talented player, has great hands and is very unpredictable," he said on-court afterwards. "You don't know what comes up next, and I had to stay focused, which I did."

Ringing phones are common at tennis events as it pertains to fans in the stands, but less so, players. But the odd scene, in fact, has precedent—and even more amusingly so, with Moutet's compatriots: Twelve years ago in Bastad, Sweden, Alizé Cornet's phone famously rang as she faced match point against Caroline Wozniacki, and earlier this spring in Barcelona, Harold Mayot's went off during his match with Cameron Norrie.

But the good-natured scene quickly gave way to a more worrying one for the top seed, who was struck in the head by a water bottle while signing autographs as he left the court after the match ended and needed medical attention.
