• Briton fights off back soreness during her 6-3, 7-5 victory
• Raducanu reaches third round in Melbourne for first time

Slowed down by a sore back, swirling wind and a supremely talented ball-striker who robbed her of rhythm, all Emma Raducanu could do was fight with all the energy, intelligence and conviction she could rouse as her presence at the Australian Open hung in the balance.

Across two testing, uncomfortable hours, Raducanu scrapped, counterpunched and she chased down every last ball, her significant efforts yielding a brilliant win as Raducanu out-hustled Amanda Anisimova 6-3, 7-5 to reach round three at Melbourne Park.
