Learner Tien will return to the Next Gen ATP Finals presented by PIF. The 19-year-old American booked his spot after a standout first full season on Tour.
The lefty ended last year by reaching the title match in Jeddah and built on that success at the Australian Open, where he defeated Top 10 star Daniil Medvedev. Tien reached the fourth round in Melbourne to become the youngest player to reach that stage at the hard-court major since Rafael Nadal in 2005.
Tien then stunned Alexander Zverev at the ATP 500 event in Acapulco, where he enjoyed a quarter-final run. He also reached the fourth round at ATP Masters 1000 events in Toronto and Shanghai.
Tien’s best result came at the ATP 250 event in Metz this month, when he won his first tour-level title, defeating Cameron Norrie in the final. The American also tasted success at the ATP 500 event in Beijing, where he reached the championship match. Tien eliminated Lorenzo Musetti and Medvedev in China. He ended the season holding a 5-4 record against Top 10 players, according to the Infosys ATP Win/Loss Index, and is at a career-high No. 28 in the PIF ATP Rankings, having started the year outside the Top 120.
The 2025 Next Gen ATP Finals presented by PIF will take place from 17-21 December. Former champions include Jannik Sinner and Carlos Alcaraz.
