Katerina Siniakova clinches year-end No. 1 doubles ranking for fourth time in her career

Katerina Siniakova, the only woman to win two Grand Slam doubles titles this year, has clinched the WTA’s year-end No. 1 doubles ranking.

It comes on the same day as Aryna Sabalenka, the only woman to win two Grand Slam singles titles this year, clinched year-end No. 1 in singles.

But while it’s a first No. 1 finish for Sabalenka, this is nothing new for Siniakova—it’s the fourth time in her career that she’s finished a season at No. 1 in doubles, having already done it in 2018, 2021 and 2022.

The Czech is the fourth woman to finish at No. 1 in doubles four or more times since official WTA doubles rankings began in 1984.

MOST YEAR-END DOUBLES NO. 1 FINISHES (since 1984):
5: Martina Navratilova [1984, 1986-1989]
4: Cara Black [2005, 2007-2009]
4: Liezel Huber [2007-2009, 2011]
4: Katerina Siniakova [2018, 2021-2022, 2024]

Three of Black and Huber’s four individual No. 1 finishes came as co-No. 1s, from 2007 to 2009. One of Siniakova’s individual No. 1 finishes came as co-No. 1, alongside countrywoman Barbora Krejcikova in 2018.

Siniakova has had far and away the best doubles season on the women's tour in 2024. She was the only woman to win two Grand Slam doubles titles this year, and she did it with two different partners, too—at Roland Garros with Coco Gauff and at Wimbledon with Taylor Townsend.

In fact, she won all five of her doubles titles this year with different partners, her other three titles coming in Dubai with Storm Hunter, Prague with Krejcikova and Guangzhou with Zhang Shuai.

She’s an incredible 48-11 this year including her first two round-robin wins at the WTA Finals, where she’s competing with Townsend. In the previous 17 events she played this year before coming to Riyadh, she reached the quarterfinals or better 15 times, the semifinals or better 11 times and six finals (winning the aforementioned five titles).

The Czech also won her first mixed doubles title this year, capturing the gold medal at the Paris Olympics alongside Tomas Machac.

Siniakova and Townsend will face Hsieh Su-Wei and Elise Mertens in their final round-robin match of the week on Wednesday.
