The American then addressed her partner, who has now won an impressive 11 women’s doubles majors.
“Kat, this has been fun. I’m really enjoying being by your side, not only as a team, but getting to know each other. Sharing these moments together strengthens our bond.
“I’m so grateful for this day, so happy, No.3 together, No.12 or 11 for you, whatever, we’re still counting. Let’s go!”
Townsend’s blazing backhand pass, dipping low into the right tramline, earned the opening break for 3-2. The American’s power combined with Siniakova’s net game cemented their dominance.
The Kazakhstani-Serbian combination, who also finished as Roland-Garros runners-up last June, fought back in the second set. Krunic managed to curl a magnificent defensive lob over the top seeds en route to an early 2-0 lead.
