The unseeded Mattek-Sands and Safarova beat five seeded pairings to win the title on Rod Laver Arena, the first of the titles to be decided at this year's Australian Open.

It was also the first time the 29-year-old Mattek-Sands and 27-year-old Safarova had played together in a tournament, and they are the first new pairing to win the women's doubles title at Melbourne Park since 2005.

Mattek-Sands won the mixed doubles title at Melbourne Park with Romania's Horia Tecau in 2012.

The victory makes up for a disappointing singles campaign for Safarova, who entered the season opening grand slam as the 16th seed but lost in the first round to Yaroslava Shvedova.

Mattek-Sands made the third round of the singles, losing to third seed Simona Halep.
