Katerina Siniakova, two couples and the same destiny

A few days have already passed, but I could close the chapter of this US Open 2026 without discussing one of the players who harvested the most glories there. Katerina Siniakova, friends. The best female doubles player of this century. Capable of completing the 'Career Grand Slam' with two different partners. Who else has done this in history? Absolutely no one.

Let’s start with the last, the most recent, the truly glorious. The Czech has just completed the doubles Grand Slam with a second different partner, something that, I repeat, no one had achieved before in history. First, she did it alongside Barbora Krejcikova. Now, with Taylor Townsend. She changed partners, changed dynamics, changed generations, but did not change her destiny. Siniakova had already won all four Grand Slams with Krejcikova: Roland Garros, Wimbledon, US Open, and the Australian Open. That pair was one of the great partnerships in women’s doubles, but the story did not end when their paths diverged.

The player who turned 30 last May long ago saw in Townsend another top-tier partner with whom to rewrite exactly that same chapter. And that is probably the most extraordinary of all, that she never needed to repeat a formula to accomplish that feat.

Two partners, one same story

With her victory in New York, Siniakova reaches 12 Grand Slam titles in doubles, an incredible number that grows even more when you add her mixed doubles crown, elevating her personal tally to 13 majors. But the figure that best explains her season is not in the Grand Slams, but in a sequence that seems written to challenge any statistic: Adelaide, Indian Wells, Miami, Madrid, Roland Garros, Toronto, and now US Open. Seven finals played, seven finals won. There is something about this woman; whatever she touches turns to gold.

“It’s really difficult to find words. I’m very proud of our team. This final was very close, very tough for us, but we found a way to win it. We found a solution when we needed it the most,” Siniakova explained after lifting the trophy against Montgomery and Krueger. There lies her virtue as a doubles player, the fact that when the match stops being beautiful and starts being uncomfortable, she finds a response.

The partnership with Townsend, moreover, was born almost accidentally: a private message on social media. Siniakova needed a partner and had seen Townsend enough times across the court to know it could work. “I knew she understood doubles, that she knew how to be at the net and that she wasn’t afraid,” the Czech said. Wimbledon was the first major confirmation of that intuition. Since then, the intuition has turned into a season that seems like science fiction: seven finals, seven titles. Not a single final lost.

They haven’t built a perfect season because they haven’t faced obstacles, but because every time they reached the last match, they found a way to walk away with the trophy. I think that is enough evidence to take a step back and observe the historical dimension that Katerina Siniakova represents. Doubles usually requires a special chemistry, an almost inseparable pair, two players who know each other even in silence. She came to prove that her greatness does not depend on a specific partner.

She did it with Krejcikova and is doing it with Townsend. Two different partners, two distinct eras, four Grand Slams completed. Someday, someone will look at this statistic and think it was inevitable, but it wasn’t. Siniakova has simply made the extraordinary start to seem customary. The best at what she does.
