#NextGenATP Learner Tien and Gabriel Debru will not soon forget their Sunday triumphs on the ATP Challenger Tour. The American Tien claimed the Cranbrook Tennis Classic in Michigan while Debru won on home soil at the Internationaux de Tennis de Troyes, becoming two of the three youngest champions on the ATP Challenger Tour this year.
Tien, 18, needed a deciding set in all five of his matches, earning a final victory against 19-year-old countryman Nishesh Basavareddy 4-6, 6-3, 6-4 to claim his maiden ATP Challenger Tour crown. In just the third final in Challenger history to feature two American teenagers, Tien fought back from a set and a break down to lift the trophy.
"Fifteen sets in five matches, went the distance in all of them. I was just really happy and relieved to get through all of them," said Tien, World No. 267 in the PIF ATP Live Rankings. "I'm really happy to get my first Challenger. That was one of the goals that I wanted to cross off my list this year."
[ATP APP]A two-time major boys’ singles finalist, Tien is the youngest American Challenger champion since 2016, when an 18-year-old Frances Tiafoe won in Granby, Canada. Tien, who arrived at the Bloomfield Hills Challenger after three consecutive trophies at ITF M15 level, is the 10th-youngest American Challenger champion since 1990.
The lefty is up 14 spots to eleventh in the PIF ATP Live Race To Jeddah. Tien is aiming for his maiden trip to the Next Gen ATP Finals presented by PIF, which runs from 18-22 December in Jeddah, Saudi Arabia.
The 18-year-old Debru became the youngest French Challenger champion since 2017 by winning in Troyes. The home favourite, 25th in the PIF ATP Live Race To Jeddah, ousted Kazakh Timofey Skatov 6-3, 6-7(1), 7-5 in the final.
