When it comes to Grand Slam action, women’s doubles has quietly been serving up some of the best popcorn matchups in recent years. Case in point: the 2025 Australian Open.
The season’s first major delivered a sizzling semifinal lineup featuring three of the world’s top teams and a pair of rising stars fresh off an Olympic silver medal.
- No. 1 Katerina Siniakova & Taylor Townsend
- No. 2 Gaby Dabrowski & Erin Routliffe
- No. 3 Hsieh Su-Wei & Jelena Ostapenko
- Mirra Andreeva & Diana Shnaider
Women’s doubles is having a moment. Marketable stars, compelling partnerships, and budding rivalries are making it must-watch tennis—not just for the niche doubles fanbase but for the broader tennis world, too.
Even journalist Ben Rothenberg, formerly of The New York Times, spotlighted the sport in Bounces, profiling the newly formed, yin-yang duo of Hsieh and Ostapenko, who reached the Australian Open final. But while their high-profile pairing and quirky combination generated significant buzz, the biggest doubles storyline coming out of Melbourne was Katerina Siniakova’s continued dominance and rise up the WTA history books.
Teaming up with Townsend, the world No. 1 claimed her 10th Grand Slam title, defeating Hsieh and Ostapenko 6-2, 5-7, 6-3 in the final. It marked her second major win with Townsend in just seven events played together and further cemented her place in doubles history.

Siniakova Knocks on the Doubles GOAT Door
With 10 Grand Slam doubles titles, Siniakova now stands in elite WTA company. The 28-year-old is the first woman to hit double-digit majors in doubles since Martina Hingis won her 10th grand slam at Wimbledon in 2015.
Siniakova seems almost unfazed by her growing legacy.
“It’s really nice that you guys are still saying it and kind of remembering it,” she told WTA Tennis. “I’m just a professional athlete, working hard and trying to get more and more. When you guys come and say, ‘Oh, you did this,’ I’m really excited. So yeah, it sounds perfect.”
But the numbers speak for themselves.
Siniakova next could pass Hingis (13) and the Williams sisters (14) on her climb up the WTA all-time doubles major leaderboard. Among active players on both the ATP and WTA tours, she owns the most doubles majors—more than Hsieh (7), former partner Barbora Krejcikova (7), Kristina Mladenovic (6) and Nicolas Mahut (6).
She’s also in rare company as a double-digit slam winner across singles, doubles, and mixed doubles, joining only Novak Djokovic (24), Venus Williams (21), and Krejcikova (12) sitting atop the active player list.
Apart from her grand slam dominance, Siniakova is also one of few tennis players to achieve the career golden slam: winning all four majors and an Olympic gold medal. In fact, she has done it twice, first in women’s doubles (with Krejcikova in Tokyo 2021) and again in mixed doubles (with Tomas Machac in Paris 2024).
How High Can Siniakova Climb?
At 28, Siniakova is arguably in her career prime. And in doubles, where players routinely compete into their late 30s or even 40s, there’s plenty of time to keep adding to her legacy.
She has already spent 135 weeks as world No. 1, the fifth most in WTA history. She’s on track to pass Lisa Raymond soon and crack the all-time top four.
If Siniakova continues winning at least one doubles slam per season, as she has for the past five years, surpassing Hingis, the Williams sisters, Billie Jean King (16), Gigi Fernández (17), and Natasha Zvereva (18) seems within reach.
Catching Pam Shriver’s 21 or Martina Navratilova’s 31 might be a long shot, but Siniakova has already solidified herself as one of, if not the, best doubles players of the current generation.
How far she climbs from here? The sky’s the limit for this modern era doubles GOAT.
