Serena Williams has suffered her earliest exit at the Australian Open since 2006 following defeat at the hands of Wang Qiang on Sunday.
The seven-time champion has been knocked out by the Chinese, losing 6-4 6-7 (2-7) 7-5.
The defeat means the 38-year-old American’s quest for a 24th Grand Slam singles title goes on.
Wang served for the match at 5-4 in the second set but Williams broke her for the first time and then won a tie-break to level at one set all.
The 27th seed recovered and sealed victory on her third match point.
“After the second set I was a little bit confused, but my mind always said I had to focus on the court, on every point and trust myself,” said Wang, who now faces Tunisian Ons Jabeur in the fourth round.
