On the Mailbag, Gill Gross unpacks Novak Djokovic’s split with Goran Ivanisevic, including the media coverage, the reasons for the breakup, who might be next and what value that person should bring to the 24-time major champion. We’ll answer your comments, including: how do we rank events in order of court speed, why Nuno Borges got robbed in Estoril, why Iga Swiatek can struggle against relentless power aggression, how Jannik Sinner will fare on clay, will Medvedev overcome his limitations, has Stefanos Tsitsipas’s forehand declined, what are the ideal surface speeds, can stats help explain errors, what to make of Dominic Thiem’s admission that his wrist still limits his power?Things I forgot to say…Regarding punishment for umpire mistakes; their performance is constantly being evaluated, so the punishment generally comes in the form of doing smaller matches.Regarding Tsitsipas’s first serve percentage; I am still perplexed by his desire to experiment with the pinpoint footwork given the effectiveness of his serve relative to other areas of his game.Subscribe to The Draw: https://www.thedraw.tennis/subscribe
