World number one Roger Federer eased past Britain's Tim Henman to reach the semi-finals of the Nasdaq-100 Open in Miami on Thursday.
The Swiss top seed broke in the fifth game of a closely-fought opening set, and saved a break point in game eight with a magnificent second serve.
From then on Henman was unable to threaten Federer and he broke twice in the second set for a 6-4 6-2 victory.
Federer faces Andre Agassi, who beat Taylor Dent 7-5 6-0, in the last four.
Henman put in a solid performance but was made to pay for every lapse of concentration, with Federer capitalising ruthlessly.
The world number one largely controlled the match from the baseline and fired several unstoppable forehands as Henman tried to take charge at the net.
"It was easier than I expected"
And despite some wonderful volleys from the Briton, Federer was more often than not able to find the winning pass.
"He's one of the guys I've got a bad record against, so it's always good to beat him," said Federer, who now trails Henman 6-4 in career meetings.
"It was easier than I expected. I thought he missed his one chance when he had break point.
"I hit a great second serve and from then on it seemed easier. In the second set I started to play better and then it was tough for him."
Henman, who still leads 6-4 in head-to-heads with Federer, tried to remain upbeat about his performance.
The 30-year-old said: "I feel somewhat disappointed with the way I played but in the context of the way I played the last couple of weeks, it's been positive.
"It was okay but I think you're only allowed to play to a certain level because of the standard that he's playing so consistently.
"There were parts where I felt pretty comfortable, but it only takes your level to drop for a point or two points and that can be a break of serve, and he just keeps rolling from there."
