Naomi Osaka won her second Australian Open title over the weekend with a straight-sets 6-4, 6-3 victory over Jennifer Brady in the 2021 Australian Open women’s final on 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 matches. 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, especially off-angled backhands.

Osaka held the advantage over 26-year-old Brady 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. She had been steadily on the rise, reaching at least the semifinals in her two previous Grand Slam events. The 26-year-old had never advanced beyond the fourth round before last year’s U.S. Open. She took the loss gracefully, saying at the ceremony’s end: “Tonight it wasn’t meant to be. 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 its heir to Serena Williams in Osaka. She defeated her hero, Serena Williams, to advance to the final. 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. Right now, the driving force is Osaka. She came into this year as the highest-earning female athlete in the world. If she continues at this level, she—and by extension women’s tennis—will only ascend. Already, Osaka is an ambassador for Nike, Mastercard and Swiss watch brand TAG Heuer. She was spotted wearing a TAG Aquaracer during her match with Brady and a TAG Heuer Carrera 160th Anniversary Special Edition for the awards presentation.

Osaka was grateful that her latest triumph 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’s 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, slated to start on 23 May at Stade Roland Garros in Paris.
