Federer, Novak barely survive tough matches at US Open...

If Roger Federer looks especially ecstatic here, it's for good reason. The man who had won 30 straight matches at the US Open barely got through the fourth round of the tournament today with a five set victory over Igor Andreev of Russia. Whew!

Meanwhile, Serbian hottie Novak Djokovic is being put through the ringer in his bid to win the US Open for the first time. He survived a tough four-setter on Sunday then had to pull out all the stops today tp get past Tommy Robredo in the fourth round 4-6, 6-2, 6-3, 5-7, 6-3. If he and Federer win their next matches, they will play in tne semifinals.
