From then on, though, they were virtually untouchable, winning 34 of their next 37 matches to take home titles at Wimbledon, the US Open, Guangzhou, Wuhan, Beijing and the BNP Paribas WTA Finals Singapore presented by SC Global.
Unsurprisingly, their remarkable feats resulted in them winning the WTA Doubles Team Of The Year award by a landslide. The pair have no intention of resting on their laurels.
"Martina and I have had an incredible year and I feel honored that we have been voted as the WTA Doubles Team Of The Year by the international media. We hope to continue with our dream run in 2016," Mirza said.
Next year, Hingis and Mirza will look to add to their already impressive trophy haul, as they chase down the greats, like former WTA Doubles Team Of The Year winners Martina Navratilova and Pam Shriver (1981-88), and Gigi Fernández and Natasha Zvereva (1993-95 and 1997).
"It is a great honor to be recognized as the WTA Doubles Team Of The Year by the international media," Hingis said. "Sania and I have enjoyed every minute of the season and we hope to continue in 2016 in the same fashion. We both appreciate all the support that we have received from the fans, the media, the tournaments and the tour."
Hingis and Mirza were the choice of 98% of the media polled for the WTA Doubles Team Of The Year award. They also won the fan vote with 58%.
