Marin Cilic triumphed in the second longest match in Wimbledon history on Saturday, while Andy Roddick lost to David Ferrer.
Cilic saw off Sam Querrey to set up a fourth-round tie against Andy Murray.
John Isner's record clash with Nicolas Mahut in 2010 will surely forever be the longest played at the All England Club, but Cilic and Querrey were in no rush either.
It went to a final set that Cilic eventually won after he broke serve in the 31st game and then held on his own delivery.
Cilic, who won the AEGON Championship at Queen's two weeks ago, slumped in his chair with relief after five hours and 30 minutes of play that ended with a 7-6 (8/6) 6-4 6-7 (2/7) 6-7 (3/7) 17-15 win for the 16th seed.
Roddick blew a kiss to the crowd as he walked away from his 2-6 7-6 6-4 6-3 defeat to Ferrer but insisted it was not necessarily a farewell gesture.
The former US Open champion has been hit form and fitness worries over recent years and is rarely considered a threat at the deep end of Grand Slams.
He remains one of the leading names on the men's tour, though, even if his results do not always suggest so, and his lingering looks to the crowd prompted an investigation in his post-match press conference.
Roddick does not turn 30 until August, but there have been mild murmurings he could be able to walk away.
"I don't have an answer for you," he said when asked about his future. "I'm not going to be able to give you much else."
But as Roddick headed back to America, one of his countrymen was making plans for an unexpected second week in London.
Brian Baker's fairytale tournament continued on Court Three as he reached the fourth round with a four-set win over France's Benoit Paire.
The 27-year-old, once one of the world's best juniors, only returned to professional tennis last July after almost six years out with a succession of injuries that looked to have curtailed his career before it had really started.
Baker went to college and took a job as a tennis coach but never gave up hope that he would be able to return to the circuit, and his comeback gets more remarkable with every match as he won 6-4 4-6 6-1 6-3 on Saturday.
"It is crazy, what's going on," Baker said. "But I'm still trying to stay focused on the task at hand and not get too wrapped up in it.
"Because once you do that, I think it's tough to be able to play your best tennis once you're happy that you've been there."
One man not so happy was Lukas Rosol, who lost his giant-killing touch as he bowed out at the hands of Philipp Kohlschreiber.
The previously-unsung Czech caused a sensation when he sent Rafael Nadal packing at the second-round stage on Thursday.
But he was unable to replicate that performance on Court 12, going down to German Kohlschreiber 6-2 6-3 7-6 (8-6).
Whether it was being away from the Centre Court limelight that affected him or the effectiveness of his opponent, the 26-year-old has still yet to reach a grand slam fourth round in his career.
His name will long be remembered, though, and he hopes he can now start to make a more consistent impact on the main tour.
"Why not?" he asked. "I can play with anyone. That's what I feel and also these players, when they see my name now, are going to see they can lose against me."
On Court Three, ninth seed Juan Martin del Potro also went through, seeing off Kei Nishikori in straight sets, and he now meets Ferrer, while Mardy Fish and Jo-Wilfried Tsonga will meet in a tasty-looking encounter.
Fish was a routine winner over David Goffin 6-3 7-6 (8/6) 7-6 (8/6) while Tsonga was largely untroubled in getting past Lukas Lacko 6-4 6-3 6-3.
The pair played out a memorable five-set duel which Tsonga won at the US Open last year, and Fish, back on tour after a recent heart scare, is eagerly anticipating a rematch.
"We will be ready to go on Monday," the 30-year-old 10th seed said.
"It's a great opportunity for Jo and I and we've got a little rematch of the US Open. It was fun last year and I look forward to it."
