On this interview edition of MMA, former Deadspin tennis writer and current Racquet Magazine Contributing Editor Giri Nathan joins me to talk about the future of tennis. Who is the most likely to win a slam in 2020 between Stefanos Tsitsipas, Dominic Thiem and Daniil Medvedev? What did Giri learn from spending time with Tsitsipas? How should Rafael Nadal, Novak Djokovic and Roger Federer feel about their seasons? And insight into what happened when the entire Deadspin staff quit the website earlier this month?
