I’m happy to have another chef in the bakery right now, said the 22-year-old young Swiatek, whose ability to demolish singles opponents by winning sets without dropping games has sparked social media jokes like “Iga’s Bakery.” No, I’m kidding. On Twitter, they said the bakery should be closed on New Year’s Eve, but here we are. I’m happy I played so well and Hubi’s a great partner for mixed doubles, Swiatek added.

Casper Ruud, who led Norway to a 2-1 victory against Croatia in Sydney, also stepped up his preparations for the Australian Open, which runs from January 14 to 28.

Caroline Garcia and Edouard Roger-Vasselin saved match points to beat Angelique Kerber and Alexander Zverev 7-6(4), 2-6, 12-10 to give France a 2-1 victory over Germany.
