CALIFORNIA – Roger Federer and Novak Djokovic cruised into the quarterfinals of the PNB Paribas Open at Indian Wells on Wednesday after Wimbledon champion Andy Murray and Australian Open winner Stanislas Wawrinka both fell in the fourth round.

In a tournament full of surprises, Federer and Djokovic struck a blow for the old world order with Federer 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 Djokivic 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 in the Californian desert.

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. 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.
Already a four-time champion at Indian Wells, Federer is now on a nine-match winning streak.
