Fifth seed Daniil Medvedev is out of the Australian Open after losing a five-set thriller to teenager Learner Tien in the biggest upset of the tournament so far.
Medvedev, a three-time finalist in Melbourne, saved match point in the third set and forced a decider, but ultimately fell to a 6-3, 7-6, 6-7, 1-6, 7-6 defeat by the 19-year-old qualifier.
American Tien, ranked 121st in the world, celebrated in front of a largely empty Margaret Court Arena after wrapping up the win at 2-hours-and- 54 seconds in Melbourne.
Before this week’s tournament Tien had never won a Grand Slam match, losing in the first round in all three of his US Open appearances.
Medvedev, who lost to Jannik Sinner in last year’s final, seemed like the clear favourite to win the match after steamrolling his way through the fourth set in 27 minutes, with Tien looking fatigued.
But, after a brief rain delay, the left-handed Californian dug deep to break back in the decider and force a 10-point tie-break.
