Milos Raonic, Borna Coric and Feliciano Lopez took time out of their busy schedule in Monte Carlo to take part in a special ATP Speedboat challenge.
The challenge, hosted by Bruno Soares, saw Raonic, Coric and Lopez attempt to hit a tennis ball through a ring on a Speedboat.
Soares was suitably dressed for the occasion, but the windy conditions in Monte Carlo made it a struggle for the talented trio. Did anyone make it?
