Federer survives, Djokovic crawls

NEW YORK: The iron will of Roger Federer and the burning desire of Novak Djokovic carried them into the quarterfinals of the US Open on Tuesday.

In a match that started under sunny skies but ended under floodlights, Russia's Igor Andreev exposed Federer's vulnerable side before the Swiss protected his four-year New York reign with a compelling 6-7, 7-6, 6-3, 3-6, 6-3 triumph.

"It was a tough match, the wind was changing with either side, it went from day to night session which is never easy. It was tough conditions but I'm happy we put on a good show," a relieved Federer summed up courtside after his 3-1/2 hour win.
