SHANGHAI (AP) — Roger Federer assured himself the No. 1 ranking for the 300th week of his career by beating Davis Cup teammate Stanislas Wawrinka 4-6, 7-6 (4), 6-0 Thursday in the third round of the Shanghai Masters.
"It's obviously an amazing number and I never thought of anything like this when I was a little kid," Federer said. "I just thought one day my dream would come true to play on the tour. So here I am at 300 weeks, and it's probably one of my biggest accomplishments and something I'm very proud of. No doubt about it."
The Swiss star will play 10th-seeded Marin Cilic in the quarterfinals after the Croat beat Fernando Verdasco of Spain 4-6, 6-1, 6-4. Novak Djokovic and Andy Murray also reached the quarterfinals. Djokovic defeated Feliciano Lopez of Spain 6-3, 6-3, and Murray beat Alexandr Dolgopolov of Ukraine 6-2, 6-2.
Murray will play unseeded Radek Stepanek of the Czech Republic. Stepanek upset eighth-seeded John Isner 6-4, 6-7 (5), 6-3.
Federer struggled with his backhand for much of the first two sets before recovering.
"I just keep on trying," he said. "I knew I had a chance going into the breaker and I was just a little lucky. But I never stopped believing. But he was the better player for two sets. It was great finding a way out."
