Danilina and Heliovaara win US Open mixed doubles title

"I didn't know you two weeks ago. Now I know you very well," Heliovaara, a native of Finland who ranked in the top 10 of men's doubles earlier this year, told Danilina in the trophy ceremony after Saturday's final at Flushing Meadows.

Danilina, who won an NCAA title at the University of Florida in 2017, was in her second grand slam final after she and Brazilian Beatriz Haddad Maia lost in the Australian Open women's doubles final last year.

With members of the Kazakhstan tennis federation in the stands watching, Danilina and Heliovaara edged ahead when they broke Krajicek's serve for a 5-4 lead in the second set. Heliovaara served it out, leaping in celebration after the final point.

Pegula and Krajicek missed out in their bid to become the first all-American team to win the US Open mixed doubles title since Melanie Oudin and Jack Sock in 2011.
