Johanna Konta became the first British woman to reach a Grand Slam quarter-final for 32 years by beating Ekaterina Makarova at the Australian Open.
Konta, making her debut in the main draw, fought back to beat the 21st seed 4-6 6-4 8-6 in the fourth round.
The 24-year-old, ranked 47 in the world, will next face either 15th seed Madison Keys or China's Shuai Zhang.
The last British woman to play in the quarter-finals of a Grand Slam was Jo Durie, at Wimbledon in 1984.
"It was mentally, emotionally and physically draining," said Konta, after a match that lasted three hours and four minutes.
