Naomi Osaka​ won her second Australian Open Title over the weekend with straight-sets 6-4, 6-3 victory over Jennifer Brady in the 2021 Australian Open​ women’s final Saturday at Melbourne Park. This marks the fourth Major title of her soaring career and the continuation of her win streak, now up to an impressive 21 wins. Osaka also won the 2020 U.S. Open, giving her back-to-back major titles for the second time. A feat She pulled off in the 2018 U.S. Open and 2019 Australian Open.

The 23 year old superstar played at her peak or very close to it this past weekend, overwhelming her opponent with heavy, pace-laced strokes, and especially off-angled backhands.

Osaka held the advantage over Brady, 26, in almost every major statistical category in the championship match, including winners (16-15), aces (6-2) and break points converted (4-2).

This was Brady’s first appearance in a Grand Slam Final, having been steadily on the rise, with two straight Grand Slam events where she at least reached the semifinals. The 26 year old had previously never advanced beyond the fourth round before last year’s U.S. Open. She took the loss gracefully, speaking at the end of the ceremony “Tonight it wasn’t meant to be,” she ​told reporters​. “Hopefully there’s many more.”

Men’s tennis may wonder who will take over from the Big Three once they retire. The women’s game seems to have their heir to Serena Williams in Osaka. Osaka defeated her Hero, Serena Williams to advance into the finals. This is her fourth major title in the last eight she has entered—but she has ascended with a Williams-esque blend of power, athleticism and cold-blooded resolve.

If you could invest in sports, you would call your broker and load up on women’s tennis. And right now, the driving force is Osaka. She came into this year as the highest-earning female athlete in the world. If she continues this level, she—and by extension women’s tennis—will only ascend as well. Already, Osaka is an ambassador for Nike, Mastercard, and Swiss watch brand Tag Heuer, Osaka was spotted wearing a Tag Aquaracer to play her match with Brady and a Tag Heuer Carrera 160th Anniversary Special Edition piece for the presentation of the Awards.

Osaka was grateful that her latest game came with fans in the stands after winning the U.S. Open without spectators amid the coronavirus pandemic.

“I didn’t play my last Grand Slam with fans so just to have this energy it means a lot,” Osaka ​said​ during the trophy presentation. “Thank you so much for coming. I feel like playing a Grand Slam is a super privilege right now and it’s something I won’t take for granted. Thank you for this opportunity.”

It feels like Osaka has now established herself as the player to beat on tennis’ biggest stages, especially considering her semifinal victory over Serena Williams, who held that unofficial title for around two decades.

Next up on the Grand Slam schedule is the French Open, which is slated to start May 23 at Stade Roland Garros in Paris.
