ORDER OF PLAY
Play starts at 3pm
Caroline WOZNIACKI (DEN)  v Jessica PEGULA (USA)
Serena WILLIAMS (USA)  v Amanda ANISIMOVA (USA) 
Asia MUHAMMAD (USA) / Taylor TOWNSEND (USA) v Coco GAUFF (USA) / Catherine McNALLY (USA)
This will be the first meeting between Serena Williams and Amanda Anisimova.
Contesting the ASB Classic for the second time, Anisimova has already progressed beyond the quarterfinal run she made in Auckland last year.
Agnieszka Radwanska was the last top seed to win in Auckland, back in 2013, when she beat Yanina Wickmayer in the final.
Caroline Wozniacki is the only non-American player to take the court on Saturday.
The WTA World No.39, who is playing in her penultimate tournament before retiring after the Australian Open, has never faced Jessica Pegula previously.
The Dane has a 61-27 record against American players, including wins in all of her last three dating back to Rome last year.
Wozniacki defeated two-time defending champion Julia Goerges in straight sets in the quarterfinals. It was a repeat of the 2018 final, which she lost, 6-4, 7-6(4).
Jessica Pegula will play her first WTA Tour semifinal since winning Washington in August.
Pegula is the only one of the four semi-finalists yet to have dropped a set in the tournament to date. She has lost just 11 games.
