Andy Murray says finishing his second-round match at the Australian Open at 4am was a "farce".
The 35-year-old's arduous five-set win over home favourite Thanasi Kokkinakis took over five hours 45 minutes.
That followed Murray's first-round victory on Tuesday, when the Briton sealed victory in four hours and 49 minutes against Italian Matteo Berrettini.
"I don't know who it's [the late finish] beneficial for," said Murray at the Rod Laver Arena after the match.
"We come here after the match and that's what the discussion is, rather than it being like, 'epic Murray-Kokkinakis match'.
