Novak Djokovic’s hamstring just about held up as the hot favourite reached the Australian Open Last 16 on Saturday, as Andy Murray’s heroic run ended in typically defiant style. Hard-hitting Aryna Sabalenka meanwhile burnished her title credentials as she barrelled into round four along with several other women’s seeds. 

An ailing Djokovic had heavy strapping and needed treatment twice on his troublesome left hamstring before defeating Grigor Dimitrov 7-6 (9/7), 6-3, 6-4 on Rod Laver Arena.
