Dabrowski and Routliffe, who began their partnership just last month, saved eight of the nine break points they faced during a match that lasted two hours, 14 minutes.
It marked the first Grand Slam title for Routliffe, who previously represented Canada, and third for Dabrowski following the mixed doubles titles she won at the 2017 French Open and 2018 Australian Open.
She really took a chance on me and I really appreciate it and love her for it," Routliffe said during their on-court interview.
Siegemund and Zvonareva, who won the 2020 U.S. Open women's doubles competition, failed to convert any of the five break point opportunities they had in a tightly-contested first set that required a drama-filled tiebreaker.
"I'm really, really proud of the way that we've stood by each other through thick and thin the last two weeks.
