Tien’s Dominant Performance at AO 2026
In a thrilling upset at the Australian Open (AO) 2026, Learner Tien delivered an emphatic performance to defeat 11th seed Daniil Medvedev in straight sets. The young American tennis star, who made his main-draw debut last year as a qualifier, has continued to impress on the big stage.
Breaking Records and Setting Milestones
With this victory, Tien not only secured his place in the quarterfinals but also set several records. He is now the youngest AO men’s quarterfinalist since Nick Kyrgios reached that milestone in 2015. Additionally, at just 20 years of age, Tien becomes the youngest American to reach a maiden Grand Slam quarterfinal since Andy Roddick achieved this feat at the US Open in 2001.
Overcoming Medvedev
The match against Medvedev was far from an easy task. The Russian powerhouse entered the contest unbeaten in 2026, having claimed a title in Brisbane just weeks prior to AO 2026. However, Tien’s determination and tactical brilliance proved too much for the three-time AO finalist.
He broke serve early in the match and maintained his composure throughout, converting 70% of his break-point opportunities while limiting Medvedev’s unforced errors.
“It feels amazing. It’s so special to do it, especially here, where it means so much to me to come back and play every year,” Tien said on court after the match. “Every year since I’ve been coming here, the crowd support has been amazing. I don’t know why, honestly.
It’s so special to come back and play in front of a crowd like this, with this much energy and support. It means the world to me to do it here.”
Looking Ahead: Quarterfinal Match Against Zverev
Tien’s next challenge is a showdown against AO 2025 finalist Alexander Zverev in the quarterfinals. The German has an impressive record of 37-1 against left-handers, with Tien being his only defeat since 2025. Despite the daunting task ahead, Tien remains optimistic and focused.
“It’s going to be a super tough match,” Tien said about Zverev. “I was able to get him the first time we played, but the second time we played he beat me pretty bad.
He plays great tennis here, the defending finalist, it’s going to be a challenge, but I’m really looking forward to it.”
Tien’s remarkable journey at AO 2026 continues to capture the attention of fans and pundits alike. His victory over Medvedev has undoubtedly cemented his status as one of the rising stars in men’s tennis.
