Britain’s Dan Evans knocked out seventh seed Marin Cilic at the Australian Open as compatriot Andy Murray progressed to the third round on Wednesday.
World number one Murray was a convincing 6-3 6-0 6-2 winner against 19-year-old Russian Andrey Rublev.
Evans earlier fought back to win 3-6 7-5 6-3 6-3 and caused a major upset against former U.S. Open champion Cilic.
It is the second time the 26-year-old British number three has beaten a player ranked in the world’s top 10.
Evans will take on Australian 27th seed Bernard Tomic or Victor Estrella Burgos of the Dominican Republic.
Murray will face American world number 32 Sam Querrey in the third round.
It took Murray just 63 minutes to race into a two-set lead against Rublev, who was making only his second Grand Slam appearance.
But there were concerns for the Scot at 1-1 in the third set when he rolled his right ankle and cried out in pain as he fell to the floor.
A tournament doctor came out to check on Murray, who expressed his discomfort towards Coach Ivan Lendl in the players’ box.
“It is just a little sore. It’s not too serious,” said Murray.
“I definitely rolled it a bit and I’m sure I’ll get some ice on it tonight. I was moving OK. I can put weight on.
“Sam Querrey in the next round will be a tough one. He’s got a big game, a big serve and takes chances with his forehand.”
Birmingham’s Evans had earlier required the third of three match points to finish off the seventh seed on his own serve.
“To come through in the last match point was pleasing for me,” he said.
“I struggled with the shade on the court and his pace on the ball was coming through pretty quick, but when the sun went down I got into the match.”
The final two sets were a tussle, with service breaks from both players, but Evans held his nerve to win.
Compatriots Heather Watson and Naomi Broady were knocked out of the women’s doubles in the first round, losing 7-5 2-6 7-6 (7-5) to Italy’s Karin Knapp and Luxembourg’s Mandy Minella respectively.
