Andy Murray saw off Nick Kyrgios in three sets to progress to the Australian Open semi-finals where he will face Tomas Berdych.
The Scot took control early on in the match, winning the first set 6-3.
Kyrgios fought back, but lost out in a tie-break to Murray in the second.
Once Murray broke to make it 4-2 in the third, the British No.1 had almost sealed the victory, eventually taking the final set 6-3.
Andy Murray says he doesn't know if will wear full Scottish attire for his wedding.
The tennis star, who beat Grigor Dimitrov at the Australian Open on Sunday, is set to marry long-term partner Kim Sears in October.
Murray was quizzed on the subject by on-court interviewer Hamish McLachlan following the Scot's victory over Grigor Dimitrov on Sunday.
Chief among McLachlan's interests was whether Murray would be wearing a suit or a kilt on his wedding day.
Murray, clearly taken a little aback by the question, replied: "I think... I am going to have both options and see what I feel like in the morning when I wake up."
Traditionally Scots do not wear any underwear beneath their kilts.
When quizzed on whether he would be wearing a kilt "properly", Murray replied: "Yeah, obviously proper kilt, yeah."
When asked if that meant he would be going "freeball" - i.e. without any underwear - Murray replied with a smile: "Exactly."

"He's played well in the slams the last year or so. Yeah, he's obviously a talented player. You know, he's one of the young guys trying to make a breakthrough, so he'll be motivated.
"Hopefully I can play a good match and make it tough for him."

Britain's Andy Murray has been seeded sixth for the first grand slam of 2015, the Australian Open, which gets under way on Monday.

The Scot, who lost to Radek Stepanek in the third round last year, said: "I'd love to win the tournament again.
"I've had some great moments on those grass courts. It's where I won my first professional match and my first title in Britain.
