Britain's Tim Henman is set for a quarter-final meeting with Roger Federer after a 6-2 6-4 win over Tomas Cakl at the ABN Amro event. The British number one was always in control against the world number 213 in the pair's first meeting.
Henman set the tone for a dominant performance with a break of serve in the first game of the match.
And it was plain sailing for Henman from then on as he gained another break in the fifth game of the second set.

Cakl had shocked Sweden's Jonas Bjorkman in the previous round - and Henman said doing some advance research on his opponent had paid dividends.
"I watched him play a bit against Bjorkman so I had a pretty good idea as to how he was going to try and play me," said Henman.
"One of the things I've been working on is concentrating on my gameplan and letting the opponent worry about me.
"I'm comfortable doing that and this was another case of it working well."
Henman has a 5-1 record in head-to-head clashes with Federer, winning their last meeting in Paris.
The Swiss player beat Andrei Pavel 7-6 (7-2) 7-5 in the second round but was hardly in spectacular form.
In other matches, Lleyton Hewitt struggled past Thomas Johansson 7-6 (8-6) 7-6 (7-3), and Juan Carlos Ferrero beat John Van Lottum 7-5 5-7 7-6 (7-5).
"Thomas is a tough opponent," said Hewitt. "He moves easily on the court and has all the strokes."
