The 6 women to be ranked at No 1 in singles and doubles at same time: Serena Williams No 3

Topping the WTA Rankings in the singles is an incredible feat now imagine being the No 1 ranked woman in the doubles as well. Quite an achievement, right?
Let’s take things further and imagine being the No 1 player in both the singles and doubles WTA Rankings at the same time.
Yes, six women have achieved this astonishing milestone and one of them is in a ridiculous category of her own.
In case you were wondering, since the launch of the WTA Rankings in 1975 a total of 29 women have been ranked No 1 in singles in the WTA while 49 have topped the doubles rankings.
Eight of them have been top in both the singles and doubles with six of them in the below list as they were No 1 in both rankings at the same time.
Reigning singles world No 1 Aryna Sabalenka has also completed the singles-doubles No 1 feat, but her achievement did not happen simultaneously as she was No 1 in the doubles back in 2021 and only became No 1 in the singles in 2024.
Venus Williams is the other one missing as she was No 1 in doubles from June until August 2010 while she topped the singles rankings in 2002.
