Former world number one Andy Murray turned back the clock in typically combative style and favourite Daniil Medvedev set up a blockbuster second-round showdown with Nick Kyrgios at the Australian Open on Tuesday.
In the women’s draw, top-10 seeds Garbine Muguruza, Iga Swiatek and Anett Kontaveit all made comfortable starts to their Melbourne title charges, while Simona Halep and Aryna Sabalenka also won despite struggling with their serves.
Emma Raducanu, the US Open champion, was also victorious on her tournament debut but there was defeat at the first hurdle for her fellow 19-year-old Leylah Fernandez — the woman Raducanu beat in the Flushing Meadows decider.
