Nick Kyrgios is set to face Milos Raonic at the Internazionali BNL d’Italia following an easy first-round win.

The 21-year-old had few problems downing local wildcard Salvatore Caruso 6-1 6-2 in one hour on Monday.

The win continues Kyrgios’s strong claycourt form, but he remains wary of the challenge awaiting him in round two.

“I’m confident going forward, but, at the same time, Raonic’s got one of the best serves in the world,” ATPWorldTour.com website quoted the Australian as saying.

“If he’s having a lights-out day when he does everything, you can’t really do too much. I’m going out there and do what I have been doing and just compete. If I happen to win, I win.”

Canadian Raonic snatched a 6-4 4-6 6-4 win against Italian Marco Cecchinato in his first-round match on Monday.

Meanwhile, France’s Jo-Wilfried Tsonga, the world No.7, has withdrawn from the tournament with a thigh muscle injury.
