The Italian, ranked World No.249, defeated Wawrinka 6-0 7-6 (2) to record his first ATP Tour victory. Having played only one ATP level match prior to their encounter, Musetti displayed poise that belied his inexperience. He maintained an aggressive approach, sending the former World No.3 packing after an hour and 24 minutes.

"First set was almost perfect. Second set he tried to play better," Musetti said. "He was focused on the match and he wanted to win the set, but I served really good. I mixed a lot with the wide serve, T and body serve. I think the serve was the key to have the lead of the game."

At just 18, Musetti is the youngest player in the Rome draw. He next faces another former Top 5 player in Kei Nishikori, who beat Albert Ramos-Vinolas on Monday evening.

"I have seen him play on television and I know he is a very tough player," said Musetti on facing the Japanese superstar. "I'm going to enjoy the victory before I start thinking about my match against Nishikori."
