Unexpected upsets across the opening round of the Australian Open

The GIST: It’s only the second round at the Australian Open (tennis’ first Grand Slam of the season), but headlines are already popping Down Under, from unexpected upsets to a Brazilian teen making a splash in his first career Slam. Ready your Wii remote and dig in.

World No. 1 Aryna Sabalenka, No. 3 Coco Gauff cruise to third round: Two-time defending Australian Open champ Sabalenka shows no signs of slowing down, defeating unseeded Jéssica Bouzas Maneiro in straight sets last night, while super girl Gauff topped Jodie Burrage in the wee hours of the morning.

• Similarly, world No. 3 Carlos Alcaraz and No. 7 Novak Djokovic (plus his new buddy) topped their unseeded opponents last night. All chalk.

Eighteen-year-old João Fonseca stuns No. 9 Andrey Rublev: The new kid on the block, teenaged Fonseca, downed 10-time major quarter-finalist Rublev in three sensational sets yesterday. The Brazilian’s tremendous Grand Slam debut continues against Italy’s Lorenzo Sonego later today.

• And the women’s side was not without stunners last night. First, unseeded German Laura Siegemund topped last year’s runner-up No. 5 Qinwen Zheng in straight sets.

• Then four-time Grand Slam winner Naomi Osaka defeated No. 20 Karolina Muchová, advancing to the third round in a major for the first time since returning from maternity leave. What can’t moms do?

American women and men dominate: Alongside the aforementioned Gauff, No. 7 Jess Pegula is through to the Round of 32, as is No. 12 Tommy Paul. Next up, a trio of red, white, and blue boys take the court for second-round action today: No. 4 Taylor Fritz, No. 17 Frances Tiafoe, and No. 21 Ben Shelton. Wave that flag.
