Day 7 at the US Open began with a shock as Ash Barty lost to Qiang Wang, ended with another one as Stan Wawrinka knocked out Novak Djokovic, and included a big victory for Jo Konta over Karolina Pliskova. Catherine Whitaker and David Law (with a quick appearance from Matt Roberts) get stuck into it all on The Tennis Podcast. How has Konta changed as a player and a person over the past few months? What is it about playing Djokovic at Grand Slams that brings out the best in Wawrinka? And how does Djokovic's defeat change the complexion of the men's tournament? Elsewhere, Federer's exceptional performance is covered, Daniil Medvedev vs. New York is enjoyed once again, and Catherine and David give their updated reaction to the on-court interview between Naomi Osaka and Coco Gauff.
