MONTPELLIER, France (AP) Second seeded Jo-Wilfried Tsonga of France needed only 45 minutes to reach the quarterfinals of the Open de Sud de France, swatting aside countryman Pierre-Hugues Herbert 6-1, 6-2 on Thursday.
Tsonga, a former Australian Open finalist, is ranked 14 but doubles expert Herbert is ranked only 96 in singles. It proved to be a total mismatch as Tsonga hit seven aces, won 95 percent of points on first serve - losing only one point on it all match - and broke Herbert's serve four times while not facing a single break point.
Tsonga next faces Russian 20-year-old Daniil Medvedev, who beat eighth-seeded Fernando Verdasco 6-3, 6-3. Medvedev was in clinical mood, taking all four of his chances on the Spaniard's serve in addition to eight aces.
Frenchmen Benoit Paire and Richard Gasquet - the two-time defending champion - also reached the last eight.
The third-seeded Gasquet broke Tunisian Malek Jaziri's serve five times in a 7-5, 6-2 win, while Paire downed fifth-seeded Feliciano Lopez of Spain 6-4, 7-6 (5).
Paire found his serving range with 14 aces and forced 16 chances on Lopez's serve, breaking him twice. He next faces Germany's Dustin Brown and Gasquet meets countryman Kenny De Schepper.
Alexander Zverev also advanced to the last eight after beating Britain's Aljaz Bedene 7-5, 3-6, 6-4 and he next faces Frenchman Jeremy Chardy.
The 19-year-old German, who took 14-time Grand Slam champion Rafael Nadal to five sets in the third round of the Australian Open, had 10 aces. But he also faced 15 break points, saving 11.
