Lorenzo Musetti has become the first player born in the year 2002 to win an official ATP match, shocking Stan Wawrinka 6-0, 7-6(2) at the Italian Open.
The 18-year-old Italian became an instant hometown hero as he dominated the three-time grand slam champion for his first win on the professional circuit.

It was just the second match on the ATP Tour for Musetti, who came through three rounds of qualifying before aggressively upending the 35-year-old Swiss to set up a second-round meeting with Japan's Kei Nishikori.
Wawrinka made a string of errors as he lost the first eight games before working his way back into the game.
However Musetti showed experience well beyond his years to hold his nerve, taking the second set tiebreak and the match.
“Remember the name,” one commentator said on Tennis TV.
Although Musetti is the first player born in 2002 to win an ATP match, Carlos Alcaraz Garfia became the first born in 2003 to achieve the feat.
Needless to say, commentators and fans were in disbelief over the never-before-seen moment.
Shapovalov and Rublev in cruise control
Earlier, Denis Shapovalov and Andrey Rublev cruised into the second round with emphatic straight-sets victories.
Canadian 12th seed Shapovalov, who reached the US Open quarter-finals last week, shook off jet lag to beat Guido Pella 6-2 6-3, firing seven aces and 23 winners past the Argentine.
Ninth seed Rublev, making his debut at the Foro Italico, beat qualifier Facundo Bagnis 6-4 6-4 to book a spot in the second round where he will face Hubert Hurkacz.
Alex de Minaur, another quarter-finalist at the US Open, was knocked out by Dominik Koepfer with the German fighting back from a set down to win 3-6 6-3 7-6(5).
In the women’s draw, Angelique Kerber was knocked out in a 6-3 6-1 defeat to Czech Katerina Siniakova while Coco Gauf won her first ever match on clay.
Kerber, who reached the last-16 at the US Open, lasted only 69 minutes on the claycourt as Siniakova advanced in straight sets with five breaks of serve.
Kerber was almost bagelled in the second set before she saved three match points to break for the first time in the contest, however Siniakova broke back in the next game to seal victory.
American teenager Gauff, playing in her first ever main draw match on clay, came back from 4-2 down in the opening set to beat Tunisian Ons Jabeur 6-4 6-3.
