Andre Agassi had few problems in booking his place in the second round of Wimbledon with a straight-sets win over Harel Levy of Israel.
The number three seed had a blistering start to the match, taking just 18 minutes to win the opening set without dropping a game.
The 1992 champion looked rusty at times, having elected not to play competitively on grass in the build-up, but he eventually emerged a 6-0 6-4 6-4 winner.
Agassi was the first player on Centre Court due to the absence of defending champion Goran Ivanisevic and last year's runner-up Pat Rafter.
"It was pretty special being out there today," Agassi said of his Centre Court start.
"It just felt great playing out there. Every time I'm on the court it brings back a lot of memories."
Fellow American Pete Sampras also made the second round with a straight-sets win over Britain's Martin Lee, but the home crowd did get to see Greg Rusedski and Barry Cowan progress.
Out on court three, Russia's Yevgeny Kafelnikov, seeded fifth, beat Slovakia's Dominik Hrbaty 6-1 7-6 7-6.
And second seed Marat Safin had an impressive 7-6 7-2 6-3 win over Frenchman Cedric Pioline.
It had looked to be a tricky first-round tie for the Russian as he faced a former Wimbledon runner-up, but after a tight first set Safin cruised to victory.
He was joined in the second round by 1996 champion Richard Krajicek, who saw off Franco Squillari of Argentina 6-2 7-5 7-6.
Krajicek was playing only his second singles match since November 2000.
"I'm very happy," said Krajicek.
"There are a lot of holes in my game - my serve is not as consistent and I'm not in the best of shapes, but it was great to be out there serving a few aces and winning."
Arvind Parmar became the first Briton to exit Wimbledon when he lost in straight sets to Sweden's Thomas Enqvist.
Parmar lost the first set in just over half an hour on Wimbledon's court two and rarely looked like causing an upset.
He eventually went down 6-1 6-4 6-4 to the 14th seed.
Mark Philippoussis of Australia beat France's Julien Boutter to make it through to the second round.
The big-hitting Philippoussis, who has reached the Wimbledon quarter-finals on three occasions, lost his opening service game and looked short of practice in the early stages.
But the wild card, who has played only sparingly this year following knee surgery, eventually overpowered his opponent to win 6-3 3-6 6-1 6-2.
