At the end of the night, Tien eliminates Medvedev from the Australian Open!
It's another surprise in the men's draw at the Australian Open 2025.
At the end of a thrilling match that lasted well into the Melbourne night, reigning finalist Daniil Medvedev was eliminated in the second round of the season's first Grand Slam.
In a match in which he fell well behind, the Russian, who trailed two sets to nil and came within a game of defeat in the third, finally overcame his handicap.
In fact, he saved a match point in the third-set tiebreak to stay alive, which gave him renewed confidence in the fourth set.
Tien let the storm pass before coming back strongly in the decisive set.
The Next Gen ATP Finals finalist saw Medvedev serve for the match at 6-5 in the final set, but the 19-year-old American held on to win the super tie-break (6-3, 7-6, 6-7, 1-6, 7-6 in 4h48).
Just before 3 a.m., the left-handed qualifier had the last word, and will meet Corentin Moutet for a place in the second week.
Having failed to reach the last step of this tournament three times in his career, Daniil Medvedev confirms that he has been struggling in recent months, having failed to win a single title in 2024.
This is the first time he has been eliminated before the second week at a Major since Roland Garros 2023, when he was beaten by Thiago Seyboth Wild in the first round.
Margaret Court Arena was the lucky charm for American players today.
Four US representatives took to the court and emerged victorious: Navarro (against Wang), Fritz (against Garin), Keys (who beat Ruse) and Tien, who beat Medvedev in a thriller.
