MELBOURNE, Australia – Learner Tien, 20, of the United States, delivered a stunning performance at the Australian Open on Sunday, defeating Daniil Medvedev 6-4, 6-0, 6-3 to reach his first Grand Slam quarterfinal. The rising American star overcame a brief interruption due to a nosebleed to overpower the 11th-seeded Russian in just under two hours. This victory marks a significant milestone in Tien’s young career and solidifies his position as a player to watch in the world of professional tennis.
The match took place at Melbourne Park on January 25, 2026, with Tien showcasing a level of play he described as the best of his career. He will now face third-seeded Alexander Zverev in the quarterfinals. The win comes after Tien’s breakout 2025 season, which culminated in an ATP Next Gen title.
Learner Tien’s Dominant Performance at the Australian Open
Tien’s aggressive play and consistent serving proved too much for Medvedev, a three-time Australian Open finalist. He broke Medvedev’s serve early in the first set and maintained control throughout the match, demonstrating remarkable composure despite the unexpected nosebleed. According to reports, the nosebleed was attributed to dry air conditions.
The second set was particularly one-sided, with Tien winning 10 consecutive games as Medvedev struggled to find his rhythm. While Medvedev briefly rallied in the third set, Tien quickly regained his dominance and closed out the match with authority. This decisive victory highlights Tien’s growing confidence and ability to perform under pressure.
A Rising Star in Men’s Tennis
This quarterfinal appearance is a historic moment for American tennis. Tien is the youngest American man to reach the last eight of a Grand Slam tournament since Andy Roddick at the 2002 US Open. He is also the youngest men’s singles quarterfinalist at the Australian Open since Nick Kyrgios in 2015.
Tien’s success is particularly notable given his relatively low seed of 25th. He previously defeated Medvedev in a five-set match at the Australian Open last year, when Medvedev was also seeded 11th, suggesting a favorable matchup for the young American. Additionally, his recent title win in Metz in November further boosted his ranking and momentum.
In contrast, Medvedev expressed disappointment with his performance, acknowledging that Tien played a superior game. He stated he was unable to match Tien’s level and conceded that the scoreline reflected the disparity in play. This loss marks another missed opportunity for Medvedev, who has reached the final of the Australian Open three times, falling to Novak Djokovic (2021), Rafael Nadal (2022), and Jannik Sinner (2024).
The match also showcased the growing depth in men’s tennis, with a new generation of players challenging the established stars. Tien’s victory is part of a broader trend of young players making significant strides on the Grand Slam stage.
Looking ahead, Tien’s quarterfinal match against Zverev will be a challenging test. Zverev is a seasoned player with a proven track record, and the match is expected to be closely contested. The outcome will likely depend on Tien’s ability to maintain his current form and effectively execute his game plan against a formidable opponent. The Australian Open continues with quarterfinal matches scheduled for Tuesday, January 27th, with the men’s final expected on January 31st.
