**Melbourne, Australia** – In a stunning upset at the Australian Open 2025, American teenager Learner Tien defeated three-time finalist Daniil Medvedev in a thrilling five-set match, 6-3, 7-6 (7-4), 6-7 (8-10), 1-6, 7-6 (10-7). The nearly five-hour battle at Margaret Court Arena saw Tien, ranked No. 121 in the world, become the youngest American man to reach the third round of the Australian Open since Pete Sampras in 1990.

Tien, who qualified for the main draw, displayed impressive resilience, overcoming a Medvedev comeback after taking the first two sets. The Russian veteran pushed the match to a deciding tie-break, but Tien ultimately secured victory with four consecutive points.

The 18-year-old’s journey to this point has been remarkable. He reached the finals of both the US Open and Australian Open boys’ singles in 2023 and boasts a career-high junior ranking of No. 4 in both singles and doubles. In 2024, he won three ATP Challenger titles, earning him a place in the ATP Next Gen Finals. He credits his parents, both of Vietnamese descent, for his success, stating they introduced him to tennis and his father coached him until age 11 or 12.

Tien will face Corentin Moutet in the third round after Moutet’s win over Mitchell Krueger. This young American’s unexpected victory is already creating significant buzz, making him one to watch in the future of men’s tennis.
