Tsonga reached the fourth round at Wimbledon in 2007
Tenth seed Jo-Wilfried Tsonga had a titanic struggle against Alexandr Dolgopolov before finally booking his place in round three at Wimbledon.
Frenchman Tsonga let a two-set lead slip in a thrilling match but finally prevailed 6-4 6-4 6-7 (5-7) 5-7 10-8.
When the fifth set reached 8-8, thoughts inevitably began to wander to the record-breaking marathon between John Isner and Nicolas Mahut.
But after squandering two match points, Tsonga finally came through.
The match was played in a great spirit and Dolgopolov, who has risen from 370 to 43 in the rankings in the past year, warmly embraced his opponent at the end.
French Open runner-up Robin Soderling had a much easier time of it is as he brushed aside Spain's Marcel Granollers in straight sets.
Sixth seed Soderling, who has never been beyond the fourth round at the All England Club, defeated Granollers 7-5 6-1 6-4 and will play Thomaz Bellucci, seeded 25, next.
Victory was all the sweeter for Sweden's Soderling after Granollers ended his hopes in the first round of the Australian Open in January.
The Swede, who ended Roger Federer's run of reaching 23 consecutive Grand Slams at Roland Garros, said afterwards: "I think I served well the whole match. But it took it a while to get used to the returns because he served really well."
Spain'sDavid Ferrer, the ninth seed, needed four sets to see off Florent Serra of France. Ferrer, who has never been beyond the fourth round here, won 6-4 7-5 6-7(6-8) 6-3 and now faces Jeremy Chardy, who came through a five-setter with Slovakia's Lukas Lacko.
Gilles Simon of France went into the third round - and a meeting with Britain's Andy Murray - without hitting a ball.
Simon, the 26th seed was handed a walkover after his Ukrainian opponent Illya Marchenko pulled out of the match with a shoulder injury.
The 25-year-old Frenchman, a former world number six, has lost three of his previous four matches against Murray. The pair have never met on grass.
Simon insisted he would be able to handle the partisan Wimbledon fans, adding: "The strong crowd is not a problem. I played Rafa [Nadal] in the semis of the Madrid Masters in 2008 and the crowd was not for me, so it will be the same. Nadal was number one and was playing amazing tennis and I won that one."
Queen's winner Sam Querrey's fine run on grass continued after he came through in four sets against Croatia's Ivan Dodig.
Dodig had a point in the fourth set tie-break to level the match at 2-2 but his American opponent saved it and turned it around to win 6-2 5-7 6-3 7-6 (12-10).
Next up for Querrey is former Wimbledon semi-finalist Xavier Malisse, who went through against Germany's Julian Reister. Unseeded Malisse, who beat Greg Rusedski en route to the last four in 2002, triumphed 6-7 (7-9) 6-4 6-1 6-4.
Italy's Fabio Fognini, conqueror of eighth seed Fernando Verdasco in the first round, continued his good run by coming from two sets down to defeat Michael Russell of the United States 3-6 5-7 7-5 7-6 (8-6) 6-3.
