In 2015, Mattek-Sands and Safarova came to the fore as one of the WTA's outstanding pairs, winning the Australian and French Opens along the way. However, Safarova's well-documented battle for fitness forced them to park their partnership for the opening months of the new campaign.
It did not take long for the spark between the two to reappear in Miami, a succession of potentially tricky opponents dispatched with increasing authority. In the final they were particularly impressive, breaking their opponents' intimidating serves five times to round off a 6-3, 6-4 victory.
Having sauntered through the draw without dropping a set, the No.3 seeds appeared on course for another remarkably straightforward victory when they took the first set and opened up a 4-2 advantage in the second. However, they were given a late scare when Babos and Shvedova drew level at 4-4 before eventually getting over the finishing line.
The result was particularly significant for Mattek-Sands, who, after triumphing in Indian Wells alongside CoCo Vandeweghe, now joins Martina Hingis and Natasha Zvereva as the third player to win both events in the same year.
