Sania Mirza completed her 90th week atop the WTA doubles rankings on Monday.

Just 10 weeks ago, the World No.1 celebrated 80 weeks ahead of the BNP Paribas WTA Finals Singapore presented by SC Global, where her ranking came under threat from the likes of Caroline Garcia and Kristina Mladenovic, and Bethanie Mattek-Sands. Mattek-Sands came within a match of unseating the Indian star by reaching the final in Singapore, only to fall to Olympic champions Ekaterina Makarova and Elena Vesnina.

In an ironic twist, Mirza will reunite with former partner Mattek-Sands to start the 2017 season at the Brisbane International, where they will be top seeds ahead of Makarova and Vesnina.

Mirza began 2016 with longtime partner Martina Hingis, with whom she won a third straight major title at the Australian Open, and came up just short in their hunt for the Non-Calendar Year “Santina” Slam. The pair split by summer, and Mirza formed a new partnership with Barbora Strycova, cementing their union with titles at the Western & Southern Open and Toray Pan Pacific Open in Tokyo.

For all she has already accomplished, Mirza still has big goals for next year, including a maiden French Open title to complete her Career Grand Slam.
