JEDDAH: The semifinal lineup for the 2024 Next Gen ATP Finals presented by PIF was confirmed on Friday following a dramatic conclusion to the group stage in Jeddah.

Sixth seed Learner Tien produced a sensational performance against top seed Arthur Fils to open the evening session with a 4-2, 4-2, 3-4 (4-7), 4-3 (7-5) victory that created an electric atmosphere inside the King Abdullah Sports City stadium.

With only the winner advancing from the Blue Group to the semifinals, the tension was present from the first point, and it ensured a match full of drama and excitement. Despite being separated by 102 places in the PIF ATP Rankings, it was the lower-ranked Tien who seized control, securing early breaks in the first two sets to take a commanding 2-0 lead.

However, Fils refused to go down without a fight. The World No.20 from France, buoyed by the majority of the enthusiastic support, soon displayed his world-class ability to fight back and win the third set. A knife-edge fourth set eventually went to another tiebreak before Tien emerged victorious to continue a remarkably successful week in his first professional tournament outside the US.

The 19-year-old was supported by fellow American Alex Michelsen during his match against Fils, but the two friends will become opponents on Saturday when they play each other for a place in the final.

Tien said: “It was great from the moment we walked out. The crowd was great, the atmosphere was really good, and it carried throughout the match, so it was really fun playing out there.”

In the first of the two winner-takes-all group stage matches on Friday, sixth seed Luca Van Assche claimed the runner-up spot in the Red Group by defeating seventh seed Nishesh Basavareddy 3-4 (2-7), 4-3 (9-7), 4-2, 4-2 following an entertaining and competitive contest.

The 20-year-old Frenchman reached the last four on his debut in Jeddah last year and has now matched that result, having secured two wins out of three in the group stage.

Van Assche will next face Joao Fonseca on Saturday for a place in the final after the 18-year-old Brazilian topped the Blue Group with a marathon 3-4 (4-7), 4-3 (10-8), 4-3 (7-5), 3-4 (4-7), 4-3 (7-5) victory over the already-eliminated third seed Jakub Mensik in the last match of the day.

On playing Fonseca in the semifinals, Van Assche said: “He’s an unbelievable talent. I practiced with him four or five days ago, so he’s a tough opponent for sure. I know that I can beat him, so it will be a very good match — a tough one. But you practice to play these matches, so it’ll be cool.”

Day three got underway with second seed Alex Michelsen confirming his place as the winner of the Red Group after fourth seed Juncheng Shang retired from their match. The 20-year-old American was leading 4-1, 1-1 before China’s Shang called time early, having struggled with illness over the last two days.

Michelsen has enjoyed a successful return to Jeddah. He went winless on his debut appearance in 2023, but has been a leading star this year, winning all three of his group stage matches to ease into the semifinals.
