US Open 2023: Swiatek, Wozniacki and Tiafoe advance on day five – as it happened

Swiatek cruises through, Tiafoe made to sweat and Wozniacki's comeback storie continues.

Townsend takes it to deuce with a wonderful return. She has an interesting approach to returning serves, starting in an almost exaggerated batting stance seen in cricket. One foot in front of the other staring down the line. It's working, she has a break point.

Townsend aces to take the first game. 1-0 up against Muchova.
