Elena Vesnina and Bruno Soares won the last four points of the match tiebreaker to capture the mixed doubles championship at the Australian Open with 6-4, 4-6, 10-5 win over Coco Vandeweghe and Hora Tecau.
It was Soares' second doubles title in 18 hours at Melbourne Park — he and partner Jamie Murray beat Daniel Nestor and Radek Stepanek 2-6, 6-4, 7-5 in a match that ended after midnight Saturday.
Vesnina of Russia and Soares of Brazil fell behind 3-0 in the tiebreaker before coming back to take a 6-3 lead, then 6-5 before taking the last four points of the match.
The official tournament program for Sunday said that American Vandeweghe had to do a computer search for Tecau's name when the Romanian approached her coach to see if she wanted to team up for this tournament — she didn't know much about his playing pedigree.
Tecau won the 2012 mixed doubles title with another American, Bethanie Mattek-Sands.
It was Vesnina's third final at Melbourne Park after making the 2012 mixed doubles final and 2014 women's doubles final. It was her sixth mixed doubles final in a Grand Slam tournament, and her first win.
