The latest ever start to a match at the Australian Open, and one of the latest ever Tennis Podcast recordings, as David Law, Catherine Whitaker and Grad Matt got together at 12:46am, with tennis still being played, to discuss the events of Day 4 at the Australian Open.The day began with Grad Matt’s quarter-final pick Viktoria Kuzmova being beaten. What happened? Is Elina Svitolina playing better than expected? And was it appropriate to ask her about her relationship with Gael Monfils?The match of the day was Milos Raonic vs. Stan Wawrinka. Did we see Goran Ivanisevic’s influence on Raonic? Despite losing, is Stan Wawrinka properly back now?In the women’s event, Serena Williams and Simona Halep remain on a collision course. But how much is Halep struggling physically?Elsewhere, contrasting late-night wins for Alexander Zverev and Novak Djokovic are discussed, there’s chat about the new Dunlop balls being used this year, and a look ahead to Day 5.The Tennis Podcast will be produced daily throughout the Australian Open (and at all the Slams) after our Kickstarter was funded by our listeners. It is produced in association with The Telegraph. See acast.com/privacy for privacy and opt-out information.
