Wins for American women sandwiched all this, with Emma Navarro getting through to the second week in her third consecutive three-set win to the start of the day.
Madison Keys got there to end the night, beating friend, compatriot and Australian crowd favorite Danielle Collins. All that was a little less surprising. Keys and Navarro have been there before, as has Coco Gauff. Paul and Gauff then kept the American mojo rolling even further, winning their fourth-round matches over Alexander Davidovich Fokina and Belinda Bencic.
Tien, 19, and Michelsen, 20, who will try to keep the vibes alive Monday in Melbourne, are on a rise that is the opposite of that. Michelsen has some past form: he made the third round in Melbourne last year and he has won a couple of first-round matches at the U.
Open in the last two years β but not like this, knocking off two top players in three matches. Tien, a two-time national junior champion, had played two Grand Slam main draw matches before this week, a four-set loss to Arthur Fils at the U. Open, and a three-set loss to Tiafoe the year before.
The third time was the charm. He beat Camilo Ugo Carabelli of Argentina in five sets. Then the draw handed him two matches against the arch antagonists of the ATP Tour, less a baptism of fire than a mind-bending trip into twisting shots, beguiling spins and the dark arts of tennis with the big boys.
