Defending champion Roger Federer eased past Lleyton Hewitt without ever hitting the heights to reach the quarter-finals at Wimbledon.
The Swiss star won 7-6 (8-6) 6-2 6-4 on a sun-drenched Centre Court.
Hewitt put up a good fight in a first set in which there were no break points, and Federer needed four set points before taking the tie-break.
The top seed then broke twice at the start of the second and raced away to win in one hour 48 minutes.
He will play grass-court specialist Mario Ancic or Spain's Fernando Verdasco in the last eight.
It was far from a flawless performance from Federer and he struggled to put away Hewitt - struggling with a hip injury - in the first set, thumping a forehand long on one of four set points.
But once he finally wrapped it up with an ace there was only going to be one winner - as there had been in the last 11 meetings between the pair.
Federer faced break points in four successive games at the end of the second and start of the third sets, but always raised his game when it mattered and never seemed unduly worried.
The Swiss had saved eight break points but got a crucial break of his own in game three of the third.
That was the decisive blow and Federer sealed victory soon after with yet another heavy serve that Hewitt could not return.

Ronnie O'Sullivan was in scintillating form at The Crucible
Ronnie O'Sullivan hit a breathtaking 147 to seal a 13-7 victory over Mark Williams and cruise into the last eight of the World Championship in Sheffield.
O'Sullivan led 9-7 going into the final session and continued to cue beautifully as he extended his lead.
Breaks of 71 and 60 added to the lead before a 100 took him to the brink.
O'Sullivan then polished his opponent off with the ninth maximum of his career and his third at the Crucible, a venue that has only seen seven in all.
O'SULLIVAN'S 147 BREAKS:
April 1997 at World ChampJan 1999 at Welsh OpenOct 1999 at Grand PrixApril 2000 at Scottish OpenOct 2001 at LG CupApril 2003 at World ChampNov 2007 at N Ireland TrophyDec 2007 at UK Champ April 2008 at World Champ
The 32-year-old will pick up a prize of £157,000 - £147,000 for the maximum plus £10,000 for the highest break - as long as no other player repeats the feat during the rest of the tournament.
The break took O'Sullivan eight minutes and 47 seconds to complete, three minutes longer than the astonishing world record time of 5:20 he set against Mick Price in 1997.
"As soon as I got on the first red I thought that I had to go for the 147," O'Sullivan told BBC Sport.
"Obviously it's more important to win the game but that money gives me a few options in the summer. I'll be getting a Bentley Convertible now - I've been dying to get one!
"The difference between this season and the last 13 seasons is that I've stumbled across a couple of things and kept my discipline with it and stayed patient.
"So I've never hit disastrous standards - before as soon as it went wrong I just wanted to get out of there."
O'Sullivan never put a foot wrong as he thrilled The Crucible crowd, while play stopped between Neil Robertson and Stephen Maguire on the other table inside the theatre.

O'Sullivan plans to spend the money on a car
In potting the 13th black, O'Sullivan released the last two reds with an exquisite cannon - and made the rest of the frame straightforward.
Former world champion Dennis Taylor, who commentated on the break for BBC Sport, described it as one of the finest positional shots he had ever seen.
O'Sullivan, who will face Liang Wenbo in the quarter-finals, now has the record for the most competitive maximum breaks, having previously been tied with Stephen Hendry on eight.
He added: "I really did think I was going to get beaten.
"I expected Mark to really make it count because he's a big game player.
"I had packed my bags because I thought it was one of those games that was going to get away from me."
Defeat for two-time world champion Williams means he will now drop out of the world's top 16, and will thus have to go through qualifying to make the ranking tournaments.
"I've made a big improvement from 12 or 18 months ago but it's still quite rubbish really," said Williams.
"I've got to go to the qualifiers now and I deserve to be going there at the end of the day. Hopefully I can try to get back into the top 16.
"I gave a lot of frames away when I was 50-odd up and kept missing frame ball.
"I could have been well in front after the first two sessions and instead he was.
"But the 147 was an excellent break. It's only him who can do a break like that and make it look so easy. I knew he was going to go for it from the moment he was going for the first red.
"He didn't look out of position once."

As Kenya's Catherine Ndereba claimed marathon gold on the final day of the World Championships in Japan.
Yamauchi, who lives in Japan, was in contention with just six miles to go but then fell away to finish in two hours 32 minutes and 55 seconds.
Ndereba broke clear in the last two miles to beat China's Chunxiu Zhou and Japan's Reiko Tosa in 2:30.37.
Briton Paula Radcliffe did not defend her title because of a back injury.
Yamauchi succeeded in reducing the leading pack from 20 to nine with an injection of pace at the 18-mile mark.
I thought this is my big chance so I've got to try, but I died a bit after that
Mara Yamauchi
But the 34-year-old soon got overtaken by her more experienced rivals, and finished in ninth - an improvement on her 18th-place finish in Helsinki.
"The men's race was decided right at the end so I thought I had to keep something in reserve," said Yamauchi.
"I thought this is my big chance so I've got to try, but I died a bit after that."

Britain's Tracey Morris, who is on the comeback trail after knee surgery, finished 19th in 2:36.40.
"I tried to put it all into this one day," said Morris, who finished comfortably.
There are seven more finals to be decided on the final day of competition in Osaka in the women's high jump, 1500m, the men's 5,000m, javelin and 800m and the 4x400m relays.

Roger Federer matched Bjorn Borg's five straight Wimbledon titles on Sunday with a 7-6 4-6 7-6 2-6 6-2 win over Rafael Nadal in a classic final.Here's what BBC Sport analyst, and three-time champion, Boris Becker made of it."It's a moment of history, matching Bjorn Borg with five consecutive Wimbledons, and Roger really deserves it. "He's been at the top of the men's game for over three years now, he's won all the major titles apart from the French Open."It's impossible to put the history out of your mind and when you see your idol, Bjorn Borg, sitting in the Royal Box it's even worse! I'm sure Roger had it in his mind and that put even more pressure on him."But all credit to Nadal. I never thought he was a contender for Wimbledon until he made the final last year, and he was a point away from going a break up in the deciding set. "I thought he was the man in control, but Federer wouldn't be Federer if he didn't know how to come back. He played like a champion in the end."The final was so good because it was number one in the world against number two. Those two guys seem to bring out the best in each other."I believe very much that Nadal is the future number one. He's only 21 years old and is improving every year. I couldn't believe how well he played in the final."What does this victory do to the 'Is Federer the best ever' debate? And will Nadal take his number one ranking soon?
