In what has otherwise become known as the Upset Open, the big names just about avoided defeat on Saturday, but The Tennis Podcast team had plenty to get their teeth into.How close did World No.1 Karolina Pliskova come to going out? Is her arm injury going to be a deciding factor in how far she goes?Much of the conversation in New York on Saturday centred around the behaviour of Fabio Fognini. The Italian had already been fined $24,000 by organisers after verbally abusing umpire Louise Engzell during his singles match, but word came through that he had been thrown out of the doubles as well. Podcast presenters Catherine Whitaker and David Law discuss the detail of the case, and have their say about what should be done about it.The Naomi Osaka vs. Jelena Ostapenko match that Catherine was so looking forward to isn’t going to happen, as both lost. Our presenters are still able to marvel at the no-look handshake Ostapenko dished out to Daria Kasatkina. They also look ahead to Sunday’s play, which is highlighted by the women’s singles matches between Wimbledon champion Garbine Muguruza and Petra Kvitova, and those involving Venus Williams and Maria Sharapova. And there’s the latest instalment of the fledgling career of 18-year-old Canadian Denis Shapovalov to discuss.A new edition of The Tennis Podcast is available to download after play every day during the US Open. Presented by broadcasters Catherine Whitaker (Eurosport, BBC 5 Live) and David Law (BBC 5 Live, BT Sport), it is produced weekly throughout the year, and daily at the Grand Slam tournaments, in association with Telegraph Sport and Eurosport.  See acast.com/privacy for privacy and opt-out information.
