Roger Federer and Novak Djokovic cruised into the quarter-finals of the BNP Paribas Open at Indian Wells on Wednesday after Wimbledon champion Andy Murray and Australian Open winner Stanislas Wawrinka crashed out in the fourth round.
In a tournament full of surprises, Federer and Djokovic struck a blow for the old world order with the Swiss beating Germany's Tommy Haas 6-4, 6-4 and Djokovic coming back to down Croatia's Marin Cilic 1-6, 6-2, 6-3.
Federer and Djokovic are the only players ranked in the world's top 10 to reach the quarter-finals after Wawrinka and Murray joined the big-name casualties when they both crashed to lower-ranked opponents on another day of upsets.
Wawrinka suffered his first loss this year when his 13-match winning streak came to a shuddering halt as he was beaten 7-6(1) 4-6 6-1 by South African Kevin Anderson.
"It wasn't really on my mind that he had won Australia," said Anderson, whose next opponent is Federer. "It feels great to beat somebody who obviously has just won a grand slam."
Murray was blown away by Canada's Milos Raonic, one of the biggest servers in men's tennis.
Despite winning the first set, the Scotsman was unable to contain the raw power of Raonic, who triumphed 4-6, 7-5, 6-3 in a little over two hours.
The fourth seeded pair of India's Leander Paes and Czech Radek Stepanek was beaten by the unseeded Swiss duo of Roger Federer and Stanislas Wawrinka in the quarter-finals of the men's doubles at the BNP Paribas Open tennis tournament here. In an encounter that lasted 79 minutes, Paes and Stepanek went down 3-6, 7-6 (6), 4-10 against the Swiss combine here Wednesday night.
India's Sania Mirza and her Zimbabwean partner Cara Black knocked out second-seeded Russians Ekaterina Makarova and Elena Vesnina 6-4, 6-1 to enter the semifinals of the women's doubles at the BNP Paribas Open tennis tournament here. They will now play fourth seeds Czech Lucie Hradecka and China's Jie Zheng.
