French Open: Tsonga finishes off Wawrinka, Del Potro beat Berdych
Paris: Local hero Jo-Wilfried Tsonga finished off Switzerland`s Stanislas Wawrinka when play resumed Monday after their marathon fourth round French Open match was interrupted by nightfall.
The fifth-seeded Frenchman had just managed to see off a fierce comeback from the 18th seed to go 4-2 up in the decider when bad light stopped play Sunday.
Tsonga rounded it off Monday for a final scoreline of 6-4, 7-6 (6), 3-6, 3-6, 6-4 and a quarterfinal match-up with World No.1 Novak Djokovic.
The 27-year-old has won only one round without dropping a set, against Italy`s Fabio Fognini in round three.
Djokovic isn`t at his freshest either after his own five-set slog against Andreas Seppi Sunday.
Spain`s Nicolas Almagro upset Djokovic`s compatriot Janko Tipsarevic earlier to set up a quarterfinal with Argentina`s Juan Monaco or second seed Rafael Nadal. Almagro, the 12th seed, won in straight sets, 6-4, 6-4, 6-4.
Elsewhere, David Ferrer sauntered into the quarterfinals with a 6-3, 6-2, 6-0 win over Spanish compatriot countryman Marcel Granollers in less than two hours.
It was a second-straight thrashing doled out by the sixth-seeded Ferrer, who dismantled Mikhail Youzhny to such an extent that the Russian scrawled the word "sorri" into the clay to apologize to the crowd for his performance in the previous round.
Next up for Ferrer is British fourth seed Andy Murray or local favourite Richard Gasquet, the 17th seed.
Juan Martin Del Potro of Argentina got past Croatia`s Tomas Berdych 7-6, 1-6, 6-3, 7-5 in another round of 16 match.
