Lorenzo Musetti achieved one of the most unique wins of his career at the Internazionali BNL d'Italia in Rome, where he finally defeated Daniil Medvedev after a two-hour, 52-minute rain delay to secure a place in the quarter-finals.
The Italian will next meet defending champion Alexander Zverev, who beat Arthur Fils 7-6(3), 6-1.
"There were a lot of rallies and I thought the level was very, very high," Zverev said of his match against Fils.
"When he came back he really won points and played really good tennis. I can't beat myself up too much, I think I did the right things. It paid off and I'm really happy with the win."
"Lorenzo is very confident now and has played well throughout the clay court season. I am looking forward to the challenge," said the German.
Mussetti was close to winning at 7-5, 5-4, 30/30, before rain fell in the Italian capital. As the rain poured down, spectators scrambled for shelter as Mussetti and Medvedev battled for another point, which the home player won with a drop shot.
