What do you get when two accomplished doubles players team up for the first time? If those two players happen to be Martina Hingis and Sania Mirza, you get a powerful force that immediately began dominating the WTA tour from their first tournament together, one that earned the WTA Year-End World No.1 Doubles Team Award presented by Dubai Duty Free.

Hingis and Mirza's season is bookended by a pair of winning streaks; the first took them through the first three tournaments of their partnership, 15 straight match wins at the BNP Paribas Open, the Miami Open, and the Family Circle Cup. In their second major tournament together, "Santina" struck gold at the All England Club, capturing the Wimbledon Championships; it was Mirza's first major title in women's doubles, and Hingis' first since the 2002 Australian Open.

Their 55-7 season record was capped by a fifth straight tournament win (ninth overall) at the BNP Paribas WTA Finals Singapore presented by SC Global, having already won a second straight major title at the US Open, and a sweep of the Asia Swing with titles at the Guangzhou International Women's Open, the Dongfeng Motor Wuhan Open, and the China Open. Hingis and Mirza head into the 2016 season with a still-unbroken 22-match winning streak, one that dates all the way back to the Western & Southern Open in August; since then, the dynamic duo have dropped just two sets.

A doubles team may only share the No.1 ranking if their best 11 results are earned together; though Hingis and Mirza are tied in total ranking points, each captured a Premier title before pairing up in March (Hingis in Brisbane with Sabine Lisicki, Mirza in Sydney with Bethanie Mattek-Sands). Should Santina stick to their plan of playing together in 2016, Hingis will ascend to co-No.1 in time for the Australian Open. In the meantime, Mirza becomes not only the first Indian woman to be ranked No.1 in either singles or doubles, she is also the first to finish a season at No.1 in either discipline - all on the back of one memorable year.
