Four-time major champion Jannik Sinner edged talented Brazilian teenager Joao Fonseca 7-6 (8/6), 7-6 (7/4) in a scintillating Stadium Court clash on Tuesday to reach the quarterfinals at Indian Wells.
The first meeting between the world No 2 Sinner and the big-hitting 19-year-old lived up to expectations, the fireworks sparking a raucous response from a crowd packed with enthusiastic Brazilian fans.
Sinner will face another fast-rising youngster in 20-year-old Learner Tien of the United States for a place in the semifinals.
Fonseca went toe-to-toe with the Italian in a tense first set but was unable to convert his lone break chance and Sinner failed to capitalise on two.
A couple of uncharacteristic Sinner errors helped Fonseca power to a 6-3 lead in the tiebreaker, but the Italian responded, denying one set point with an ace to launch a run of five straight points that sealed the set.
Sinner looked headed to a comfortable victory with a break for 4-2 in the second, but Fonseca wasn’t about to go quietly.
He broke Sinner to love in the ninth game and held for 5-5 as they went to a second tiebreaker.
An ace gave Fonseca a 4-3 lead in the decider, but Sinner surged home with four straight points, polishing off the win with a masterful forehand service return.
“I felt like trying to be as aggressive as possible was the key,” said Sinner, who is chasing a first title in the prestigious Masters 1000 event in the California desert.
“Joao’s an incredible talent, very powerful from both sides. He was serving very well.
“Maybe he dropped a little bit at the end of the second set, but I’m very happy to get through,” Sinner added.
Tien saved two match points to reach his first Masters 1000 quarterfinal with a 4-6, 6-1, 7-6 (7/4) victory over Spain’s Alejandro Davidovich Fokina.
