#NextGenATP Italian Lorenzo Musetti earned his first Top 5 win Thursday when he upset World No. 4 Casper Ruud 4-6, 6-4, 6-4 to reach the quarter-finals at the Rolex Paris Masters.

The 20-year-old played with confidence throughout the two-hour, 19-minute clash in the French capital, striking 37 winners as he pulled the Norwegian from corner to corner to reach his maiden ATP Masters 1000 quarter-final.

“I am really happy,” Musetti said. “I think we played a great match until the end. A lot of remarkable shots from his side. He was playing really well and I had to play my best tennis to beat him. I am really happy that all the hard work I am doing keeps improving me. I am really proud of this win.”

Musetti, who entered the match holding a 0-6 record against Top 5 players, will next play sixth-seeded Serbian Novak Djokovic or Karen Khachanov. He is making his second appearance in the French capital, having advanced to the second round last year.

The Italian is currently at No. 23 in the Pepperstone ATP Rankings after soaring to his second tour-level title in Naples last month. He can rise into the Top 20 in the Pepperstone ATP Live Rankings if he wins his next match in Paris. Musetti will finish his season next week at the Intesa Sanpaolo Next Gen ATP Finals in Milan, where he will be the top seed at the 21-and-under event.

Ruud, who has won three tour-level titles this season, will turn his attention to Turin, where he will make his second consecutive appearance at the Nitto ATP Finals.
