Siniakova expects “another tough, tough battle", against the American-Polish team.
“I think Bethanie and Iga, they played [a] few tournaments together, so they know each other. They're playing really great and aggressive. We know Bethanie a long time. It's going to be a hard doubles match.”
It will be the first Grand Slam women’s doubles final for the 36-year-old Mattek-Sands since she sustained a gruesome knee injury while playing at Wimbledon in 2017.
“You have to just take it all in,” said Mattek-Sands, a five-time major doubles winner. “You never know what's going to happen the next week, the next year. I think it's all about staying in the moment. Sunday will come, we'll be ready, we'll bring the energy. Till then we're going to enjoy the next couple days.”
