Emma Raducanu was a winner at a grand slam again, comfortably beating Shelby Rogers to reach the second round of the Australian Open.
She was joined by Cameron Norrie, Katie Boulter and Jack Draper, who struggled in the heat but came from two sets to one down to beat American Marcos Giron before immediately running to a courtside bin to vomit.
Dan Evans was unable to make it a British full house, losing to Lorenzo Sonego, but it was a good day for the big names, with Carlos Alcaraz, Iga Swiatek and Elena Rybakina all winning.
