On his grand slam debut, João Fonseca, an 18-year-old Brazilian, beat Andrey Rublev, while there were also wins for Katie Boulter, Daniil Medevdev and Elena Rybakina

Musetti, seeded 16, has taken the third-set breaker to lead Arnaldi by two sets to one; Shelton, seeded 21, leads Nakshima 7-6 7-5 6-5; and Popyrin and Moutet are locked into another brutal game, the clock ticking towards seven minutes when the Frenchman finally secures his hold for 2-1 in the first.

Yet more Italian excellence: Cobolli – a favourite of Coach Calv, our resident expert, who thinks he’s got the lot – leads Etcheverry 7-6. That breaker went to 10-8 and I’d not be surprised if we see a few more in a match that has potential to go on for epochs.
