Andy Murray cruised into the semi-finals of the Brisbane International with a 6-2 6-2 win over doubles partner Marcos Baghdatis.
The top seed raced out of the blocks, taking a 4-0 lead in the first set.
The start of the second set was much tighter, until Murray broke Baghdatis's serve in the fifth game.
"I played very well. I moved very well from the start - which wasn't the case in my first two matches - so I'm really, really happy," said Murray.
"The aches and pains I had from the first two matches have gone, so it's good."
Next up for the Scot will be 19-year-old Australian eighth seed Bernard Tomic, who defeated Uzbekistan's Denis Istomin 6-3 7-6 (7-4).
"Tomorrow will be a test for me to see where I am," said Tomic. "I am ready. I know I can take sets off these guys. In a best-of-three match like this, maybe I can pull off a win."
Murray and Baghdatis had teamed up in the doubles, going out in the quarter-finals on Thursday, but Murray showed no mercy as he put on a ruthless display at the Pat Rafter Arena.
A Baghdatis double fault handed Murray the opening game, before the Scot clinched a second break to love in game three.
Baghdatis eventually got on the board by holding serve at the third time of asking but never looked like threatening the Murray serve as the Briton held firm to win the opening set.
The Cypriot held his opening two games in the second set, forcing a break point in game four, which Murray saved by serve-volleying.
Murray made his rival pay for that missed opportunity by securing a break of his own in the next game, and consolidated that advantage by holding serve - saving another break point - to go 4-2 up.
Crowd favourite Baghdatis had run out of steam and another break followed as Murray completed an impressive win with minimum fuss.
Gilles Simon, the second seed, and Alexandr Dolgopolov, the third, also claimed their places in the last four.
But most of the attention on Friday will centre on the match between Australia's teenage hope and Britain's world number four.
"He's very unorthodox, very different to a lot of the guys on the tour nowadays," Murray said of Tomic, last year's Wimbledon quarter-finalist.
"He's quite unpredictable. He can play a couple of games where he doesn't do much, then he can play three or four great games, so you have to be on the ball against him mentally."
