Italian teenagers Jannik Sinner and Lorenzo Musetti scored a pair of wins to lead the youth movement on a rainy Wednesday at the ATP event in Lyon.
Sinner, seeded sixth, fled the court during a second-set thunder and lightning storm but returned to defeat Australian Open semi-finalist Aslan Karatsev 0-6, 6-3, 6-4.
Compatriot and fellow 19-year-old Musetti moved into the quarter-finals at the expense of American Seb Korda, 20, with a 6-3, 1-6, 6-4 victory.
The win earned revenge for a loss to the Russian in the Dubai quarter-finals last March.
Sinner spent two-and-a-half hours on court, breaking Karatsev three times.
Musetti, ranked 88 and an Acapulco semi-finalist this season, won his battle of former Australian Open junior champions despite a 77-minute pause due to the weather.
The Italian said he needed to regroup after a poor second set in which Korda
won 12 of the 15 points and swept five consecutive games to level at a set each.
“”I lost my focus and he won the second set easily,” Musetti said.
“I started the third set well with a break up, but then Sebi came back and he was playing really well.
“I played with my heart and my body. I am really proud of myself.”
Musetti was able to seal victory after the pair exchanged third-set breaks, with the Italian breaking in the final game to reach his third quarter-final this season.
