Wimbledon champion Roger Federer took just 11 minutes on day four to wrap up a convincing 6-2 7-5 6-1 win over Argentine teen Juan Martin del Potro.
Federer took just over an hour and a half to ease past Del Potro
After an overnight rain delay, Federer returned with a two-set lead and soon secured his 50th straight win on grass.
There were also wins for Rafael Nadal, Lleyton Hewitt and Novak Djokovic on a day uninterrupted by rain.
Weather permitting, Federer now faces a tough third-round clash with Marat Safin on Friday.
"I have Safin now," he said. "Hopefully we'll get through it and then have the weekend to rest. I just hope I can keep my good level for tomorrow."
The Swiss, aiming for a fifth straight Wimbledon crown, sped through the first set against Del Potro, breaking in games six and eight.
The 18-year-old put up more resistance in the second, until an error on a forehand in game 12 handed Federer the set.
I hope Safin's not going to have one of those crazy good days against me
It was a consummate performance from the champion, who will equal Bjorn Borg's record of five successive Wimbledon titles with victory in this championship.
In fact, Del Potro could only register one game once the match resumed, finally clicking on his own serve in game six.
However, it only delayed the inevitable, with Federer booming down a series of unreturnable serves and proving indomitable at the net as he strolled through.
"I was in control right away and felt good out there," said Federer, 25. "It was done with quickly, which was what I was hoping.
"I expect a tough match against Safin. I hope he's not going to have one of those crazy good days against me."
The Swiss will face former world number one Safin in the third round, after the Russian beat Pakistani Aisam-ul-Haq Qureshi 6-4 6-2 7-6 (7-4).
Qureshi, the first Pakistani to play in the Wimbledon men's singles in 31 years, was caught out by a series of lobs and passing shots from the former US and Australian Open champion, who is seeded 26th here.
The Russian broke once in the first and twice in the second, but had to rely on a tie-break in the third to seal victory.
He duly won that, despite good support for Qureshi from a vocal Pakistan contingent on Court 18, though he admits the Federer match will undoubtedly prove a tougher test.
"It's a huge challenge," said Safin, who beat Federer in the semi-finals en route to winning the Australian Open crown in 2005.
"He's playing great tennis but if I want to have a chance at least to be close to beat him I have to give my best game and go for it."
Djokovic had to dig deep to beat American Delic in four sets
Elsewhere, fifth seed Nadal enjoyed an easy day's work with a 6-2 6-4 6-1 second-round victory over Austrian Werner Eschauer.
The Spaniard actually lost the opening two games, but produced some outstanding groundstrokes thereafter on his way to a comfortable win and he will now face 28th seed Roger Soderling of Sweden, who beat Sebastian Grosjean 6-3 3-6 6-3 6-2.
It was a good day for the seeds in general, though sixth seed Nikolay Davydenko had to battle from two sets down to reach the third round as he finally beat Australian Chris Guccione 3-6 5-7 7-6 (7-5) 6-4 6-2.
Fourth seed Djokovic needed four sets to get past world number 67 Amer Delic, finally seeing off the American 6-3 3-6 6-3 7-6 (7-4).
Australian 2002 champion Hewitt steamrolled through his second-round match against Italian Simone Bolelli 6-2 6-2 6-1.
American ninth seed James Blake enjoyed a second straight-sets win to move into the third round, defeating Romania's Andrei Pavel 6-4 6-3 6-3.
The 15th seed Ivan Ljubicic needed just over an hour-and-a-half to get past Czech Jan Hernych 6-4 6-3 6-4 in his rain-delayed second-round match.
Frenchman Paul-Henri Mathieu faces the big Croatian next after he upset Spanish 17th seed David Ferrer 6-3 6-4 6-3.
Briton Jamie Baker's first-round conqueror Edourd Roger-Vasselin of France continued his good form with a 7-6 (7-3) 6-4 7-5 defeat of Argentine 24th seed Juan Ignacio Chela.
Big-serving Australian Wayne Arthurs put paid to the chances of Spanish 11th seed Tommy Robredo with a 6-3 7-6 (7/5) 6-3.
