Mark Philippoussis set up a fourth-round tie with Tim Henman as he battled past Fernando Gonzalez 6-4 6-1 6-7 (4-7) 7-5 on a raucous Court Two.
He wrapped up the first set after gaining the crucial break in the 10th game and then raced to a 5-0 lead inside 15 minutes in the second.
Gonzalez then began to rattle last year's runner-up and snatched the third set on a tie-break.
The fourth set was nailbiting until the Australian sealed victory with a break.
"It was definitely a little better from my last match," said Philippoussis.
"I'm just happy with the way I kept my cool.
"Every match gets a little better, that's what you're looking for in a Grand Slam."
Wayne Ferreira bowed out of his final Wimbledon in quiet fashion when he lost 4-6 6-4 6-1 6-4 to debutant Florian Meyer out on Court Seven.
The South African, playing in a record 55th consecutive Grand Slam, plans to retire after this year's US Open.
"I shouldn't have lost the match," he said. "The US Open is OK but this was the last big event I wanted to play.
"I've been very privileged to be able to spend 15 years doing something I love and it'll be sad to leave it."
Unseeded Croatian duo Mario Ancic and Ivo Karlovic both caused upsets to secure places in the last 16.
Ancic, tipped by some pundits to be as successful as his compatriot Goran Ivanisevic, stunned 25th seed Dominik Hrbaty of Slovakia 7-5 6-3 7-5.
The giant Karlovic - he stands 6ft 10ins tall - needed four sets to beat Spain's 18th seed Feliciano Lopez.
Karlovic, who famously defeated Lleyton Hewitt in last year's first round, won 7-6 (14-12) 7-6 (7-3) 6-7 (2-7) 7-5.
American Vince Spadea ended the hopes of eighth seed Rainer Schuettler with an assured display on Court Three.
Spadea broke the German straight away and never looked back as he won 6-4 6-2 6-3.
Sweden's Thomas Enqvist, a quarter-finalist here in 2001, crashed out after a marathon five-setter with the never-say-die Dutchman Sjeng Schalken on Court 13.
Schalken, the number 12 seed, nailed the 5-7 6-2 3-6 7-6 (10-8) 6-2 win with victory in the fourth-set tie-break.
On Court 18, Joachim Johansson defeated fellow Swede Jonas Bjorkman, the number 17 seed, in a tight four-setter 6-7 (5-7) 7-6 (7-5) 7-6 (8-6) 6-3.
