Millman, ranked 235th in the world, defeated Kyrgios in the first round of the US Open.

Nick Kyrgios has lost in the first round of the US Open. He was ousted by fellow Australian John Millman in four sets: 6-3, 1-6, 6-4, 6-1. The 22-year-old Kyrgios looked like one of the hottest prospects of the entire draw after reaching the final in Cincinnati (loss to Dimitrov). A rematch of the epic Miami encounter with Roger Federer awaited in the fourth round, but instead, Kyrgios will have to pack his bags after the shocking first round defeat.

Millman, 28 years of age, was the better player throughout the first set and deservedly took it: 6-3. The upset was on the cards, but Kyrgios looked determined to turn the match around. He did just that. Well, at least for one set. Kyrgios, seeded 14th, only let one game slip away in the second set, taking it 6-1.

While most viewers certainly expected Kyrgios to pull away after leveling the match, Millman stepped up once again. The Australian, now ranked 235th (!) in the world, won the important third set and then returned the breadstick favor to Kyrgios in the fourth with a 6-1 scoreline.

The upset is the biggest one of the US Open on the men’s side so far and means that Kyrgios will have to wait for the Australian Open next year for another shot at Grand Slam glory. However, for Millman, the win means an unexpected place in the second round where he will face either┬áMalek Jaziri or Thiago Monteiro.
