French Open: Sixth Seed Alexander Zverev Cruises Into Fourth Round

German sixth seed Alexander Zverev eased into the French Open last 16 for the fourth successive year on Friday with a straight-sets win over Serbia's Laslo Djere. The 24-year-old, last year's US Open runner-up, saw off the 55th-ranked Djere 6-2, 7-5, 6-2 on Court Philippe Chatrier. The comfortable nature of victory was welcome for Zverev, who had fought back from two sets down to beat unheralded compatriot Oscar Otte in round one before edging three tight sets against Russian qualifier Roman Safiullin.

"This is the main goal of my tennis career, to win Grand Slams, to reach the top of the rankings. I feel like the last year I'm on the right track again," said Zverev, in the opposite half of the draw to Rafael Nadal, Novak Djokovic and Roger Federer.

He will next face former world number four Kei Nishikori, whose third-round opponent Henri Laaksonen retired injured following the opening set, for a quarter-final spot.

Rain briefly hit Roland Garros on Friday, but Zverev and Djere were able to continue under the Chatrier roof.

The world number six, who beat Nadal en route to the Madrid Open title last month, struck 31 winners and four aces past Djere.

He dragged himself out of difficulty in the second set, saving three set points at 3-5 down on Djere's serve, but won 10 of the next 12 games.
