Daniil Medvedev’s Australian Open campaign came to an end in the fourth round after losing to Learner Tien in straight sets.
Medvedev, a three-time finalist at Melbourne Park, was beaten 6-4, 6-0, 6-3 by Tien, who advanced to a maiden Grand Slam quarterfinal.
The 20-year-old American was simply too good and will now be faced with third seed Alexander Zverev in the last eight.
Leading up to the Australian Open, Medvedev was in fine form, having won the Brisbane International to kick-start his season.
He had clinched three hard-fought victories at the first major of the year, but the former world number one simply had no answer for Tien.
Daniil Medvedev receives his first bagel in Grand Slam history
Medvedev’s chances of reaching the quarterfinals really started to slip away from him in the second set, when Tien began dominating.
Tien took the second set 6-0, which marked the first bagel Medvedev had been on the receiving end of at a Grand Slam in his entire career.
What has been the biggest upset at the Australian Open so far?
The 6-0 scoreline came in the 451st set of Medvedev’s Grand Slam career, according to Opta Ace.
Tien now leads Medvedev 3-1 in the head-to-head, having won a treble of meetings with the 2021 US Open champion in the past year.
Last season, he beat him at both the Australian Open and the China Open, before suffering his first defeat in the rivalry at the Shanghai Masters.
Learner Tien’s Australian Open campaign so far
Tien came into the Australian Open having suffered an early exit at the Brisbane International, where he lost to compatriot Alex Michelsen in his second match.
He quickly bounced back in Melbourne, however, emerging victorious in a five-set thriller against Marcos Giron in the first round.

In round two, Tien beat Alexander Shevchenko in four sets, before earning a straight-set triumph over Nuno Borges to set up the clash with Medvedev.
The young US star will now have the chance to make his first Grand Slam semifinal with a win over Zverev.
He is tied 1-1 in the head-to-head with the German, who won their last meeting on the tour at Roland Garros in 2025.
