Home hope Jo-Wilfried Tsonga needed only four games to make his way into the French Open quarter-finals for the first time when his fourth-round clash with Stanislas Wawrinka resumed on Monday.
Tsonga and Wawrinka were beaten by the light on Sunday night, but the Frenchman took little time to win through on the resumption.
The fifth seed led 4-2 in the fifth set when play was called off, and it looked like that had played into Wawrinka's hands when the Swiss broke back.
But Tsonga pressed hard with Wawrinka serving to stay in the match and, although the 18th seed saved one match point, on the second he had no answer to his opponent's powerful forehand.
With the 6-4 7-6 (8/6) 3-6 3-6 6-4 victory, Tsonga booked a last-eight meeting with world number one Novak Djokovic.
For Tsonga, it was revenge for last year, when Wawrinka fought back from two sets to love down to beat the Frenchman.
Tsonga said: "It was very intense, because we stopped on Sunday. All night and this morning I thought about how I will do, how I will play, and if I will win or not. Then when I won the last point, I felt free. That's why there is a lot of emotion."
Looking ahead to Tuesday's clash with Djokovic, he added: "It's going to be a very difficult match. But obviously I'll fight like a lion and we'll see the result. But I'll do everything I can to make it a difficult match for him."
