Jasmine Paolini just pulled off another one of those matches that makes you wonder if she’s secretly part machine, part tennis wizard. The Italian powerhouse clawed her way past Veronika Kudermetova in a Cincinnati Open semi-final that had more ups and downs than a roller coaster designed by someone with serious commitment issues.

Iga Swiatek said it was important not to be lazy, as she shrugged off weariness to partner Casper Ruud to back-to-back wins in the revamped mixed doubles competition at the US Open on Aug 19.

“Honestly I think actually it’s kind of nice for the recovery," Swiatek said.
