Scot marches on
Evans joins Murray in Melbourne round four
It gives Britain two men in the fourth round of a Grand Slam for the first time since 2002.
Evans, the world number 51, defeated home favourite and 27th seed Bernard Tomic with a 6-3 7-6 (7-2) 7-6 (7-3) victory.
Tim Henman and Greg Rusedski were the last male pair to reach the fourth round, at Wimbledon 15 years ago.
British number three Evans has never made it so far at a Grand Slam, and he will now play French 12th seed Jo-Wilfried Tsonga.
Murray eased through after a straight sets victory over the US giant Sam Querrey 6-4 6-2 6-4 in just under two hours.
The Scot will play Germany’s Mischa Zverev, world number 50 and elder brother of ATP wonder boy Alex ‘Sascha’ Zverev, after defeating Tunisia’s Malek Jaziri 6-4 4-6 6-3 6-0.
Speaking on court after his victory, Murray said: “It was obviously tough. Sam, especially in the first set, was hitting big serves. The key moment was saving break point and breaking the next game – I had the momentum.”
On his ankle problem, he said: “I felt better and better as the match went on. I was hesitant at the beginning but I was moving well at the end.”
Defending women’s singles champion Angelique Kerber beat Czech Kristyna Pliskova to reach the last 16.
The German top seed won 6-0 6-4 and will face Coco Vandeweghe who defeated Canada’s Eugenie Bouchard 6-4 3-6 7-5.
