Novak Djokovic was in imperious form as he ended Yen-Hsun Lu's fairytale run at Wimbledon with a straight-sets demolition on Court One.
Third seed Djokovic was never in any danger of slipping up in a one-sided quarter-final contest and the Serbian eased to a 6-3 6-2 6-2 victory in one hour and 51 minutes.
The victory moves Djokovic into the semi-finals at the All England Club for the first time since 2007.
Djokovic said: "Nothing is easy, especially at this stage of the tournament but the way I have played I think I deserved to win.
"I was hitting all the shots and was really playing very solid from all parts of the court, so I am very happy with the performance today."
Both men saw off strong opposition in the previous round to reach the last eight, Taiwan number one Lu causing a major upset to oust last year's runner-up Andy Roddick and Djokovic beating 2002 champion Lleyton Hewitt.
It was Djokovic who settled to his task quickest today and applied early pressure as world number 82 Lu was forced to save two break points to hold for 2-2.
Lu buckled under the pressure of two further break points on his next service game as Djokovic assumed control of the first set.
Lu, the first Asian player in 15 years to reach the last eight of a grand slam, was in trouble early in the second as Djokovic continued his impressive form.
The Serbian, dictating the pace of the match with measured groundstrokes, managed another break to move 3-2 ahead as Lu fired wide.
The 2008 Australian Open champion demonstrated his appetite for the contest on Lu's next service game as he chased down a drop shot to play a cute half-volley backhand winner at the net, which he celebrated with a leap and a pumping fist.
Djokovic continued to press and moved a double break up by taking the seventh game. Lu battled well to save four break points but fell down on the fifth as he again drilled the ball wide of the tramlines.
A forehand return winner in the opening game of the third set gave Djokovic three break points, and he converted at the second time of asking with a fearsome cross-court backhand.
Djokovic's form remained ominous and his athleticism was again in evidence as he chased down a shot on the baseline he had no business reaching to force a subsequent error from his opponent.
A second break of the set moved Djokovic 4-1 ahead and left Lu facing up to the harsh reality check of a heavy loss.
"I sincerely hope I continue at this level," Djokovic told the BBC.
"You never know how you're going to wake up in two days' time, but the way I have been playing, match after match, is very encouraging.
"I have nothing to lose in the semi-finals."
Djokovic's last appearance in the Wimbledon semi-finals ended in disappointment as he was forced to retire with a foot injury against Rafael Nadal, but he envisages no such problems come Friday.
"This time physically I'm fitter," he said.
"There were very strange circumstances [in 2007]. I had to play three matches in three days, and very long matches, and unfortunately could not hold on in that semi-final, but this time everything is in order and I will give my best."
