Jo-Wilfried Tsonga's victory over Mardy Fish saw the flamboyant Frenchman complete the men's quarter-final line-up at Wimbledon following another rain-affected day.
The fifth seed started a set down after yesterday's downpour but recovered to record a 4-6 7-6 (7/4) 6-4 6-4 success, despite two more lengthy rain delays.
Tsonga, a beaten semi-finalist last year, celebrated with his familiar dance and will face Philipp Kohlschreiber in the last eight after the 27th-seeded German beat American qualifier Brian Baker 6-1 7-6 (7/4) 6-3 on Court 12.
Tsonga expects Kohlschreiber to raise his game considerably in his first Wimbledon quarter-final.
The 27-year-old Frenchman said ahead of their Court One showdown: "He has never reached the semi-finals, so of course he will play hard. I expect to have a very, very tough match.
"Maybe you will say I'm the favourite because I have played against him now many times. So I'm the favourite. "I just have to play my game."
Fish was left to rue what might have been after he watched his overnight lead dissolve amid the rain delays on Court Two.
He said: "I really felt like the way that I was playing yesterday.
"I went to bed last night and I thought I could maybe win the tournament the way I was playing.
"I played well enough to win. I would have beaten a lot of players today. He's one of the best players in the world on this surface and one of the best players in the world, period. So obviously there's a reason.
"I was certainly satisfied with the way I competed and the way I played.
"He didn't play as well yesterday as he did today. I played better yesterday than I did today maybe. So who knows what happens if there's not a rain delay."
Spaniard David Ferrer is through to meet Andy Murray in the quarter-finals.
The match comes four weeks on from Murray losing at the same stage to Ferrer in the French Open.
Fourth seed Murray saw off Marin Cilic to reach the quarter-finals for a fifth successive year at his home grand slam.
Seventh seed Ferrer ousted Juan Martin del Porto beneath the roof on Centre Court, going through 6-3 6-2 6-3 to set up his first appearance in the last eight at Wimbledon.
The Spaniard held the upper hand throughout the first set as Del Potro struggled to find his range, before cruising to a routine win over the Argentinian.
Ferrer, who has beaten Murray in their last two meetings, cast the Scot in the role of favourite ahead of their clash.
He said: "Maybe he has more pressure than me because he plays at home with your people.
"I played him four weeks ago on a clay court and now I will play with him on a grass court.
"He's the favourite player (to win) because he's better than me, and tomorrow I will try to do my best. I will have to play my best tennis to beat him."
Florian Mayer finished off Frenchman Richard Gasquet to line-up a Court One quarter-final against top seed Novak Djokovic, who was a winner yesterday against fellow Serbian Victor Troicki.
Mayer claimed the first two sets before the Frenchman hit back in the third, but the German held on to win 6-3 6-1 3-6 6-2.
Six-time champion Roger Federer and first-time quarter-finalist Mikhail Youzhny, who both won through yesterday, open the play on Centre Court tomorrow at 1pm.
