After the earliest finish of the tournament so far, David Law, Catherine Whitaker and Grad Matt look back on another dramatic day, headlined by Karolina Pliskova’s victory over Serena Williams. In what way is Karolina Pliskova’s new coaching set-up helping her? How much was Serena’s ankle injury to blame for her final set capitulation? And how much of a missed opportunity was this for Serena in her quest to win a 24th Grand Slam?Pliskova will play Naomi Osaka next after she beat Elina Svitolina. Who will have the edge in that match? In the men’s draw, Kei Nishikori was forced to retire against Novak Djokovic. Why was there a sense of inevitability about the whole thing? Djokovic’s semi-final opponent will be Lucas Pouille. How impressive were his tactics to beat Milos Raonic? And what influence is Amélie Mauresmo having on his game? Looking ahead to Day 11, who will reach the women’s final? And can Tsitsipas beat Nadal? The Tennis Podcast will be produced daily throughout the Australian Open (and at all the Grand Slams in 2019) after our Kickstarter was successfully funded.
