Ashleigh Barty and Katerina Siniakova secure WTA World No.1 rankings 2021.

Wimbledon champion Ash Barty finished No. 1 in the WTA singles rankings for the third consecutive season, while Katerina Siniakova topped the doubles rankings for the second time.

Barty, a 25-year-old from Australia, joins Serena Williams, Steffi Graf, Martina Navratilova and Chris Evert as the only women to lead the year-end tennis rankings three straight times.

This week is Barty’s 95th in a row atop the WTA and 102nd overall.
