Novak Djokovic just survived a heart-racing four-hour, 44-minute, five-set test, winning 7-6 (7-2) in a tie-break in the final set. Djokovic survived a two-set-to-one deficit and cramps in both legs.

"The match is unforgettable, I hope you enjoyed it, thanks for coming," Djokovic said at the end.

We'll have so much more shortly.

A barn-burner at Louis Armstrong: Novak Djokovic has won the fourth set 7-5 in a remarkably challenging second round match against the gangly veteran Radek Stepanek. They’ve been on the court for 3 hours and 45 minutes and both players are feeling it. Djokovic had a trainer come out twice in the third and Stepanek called for the medical assistance at 4-5 in the fourth set.

By the way, Djokovic never makes it easy. At Wimbledon alone, he played in 10 tie-breaks during his trip to the Semis. I'll keep you updated.

The Ahsha Rolle story is over, as Marat Safin's sister Dinara Safina put her away in straight sets. Justine Henin once again rolled in straight sets, 6-0, 6-2. She's trounced her opponents 36-9 through three rounds.

Novak Djokovic and the grisly Czech veteran Radek Stepanek are playing a thrilling match at Louis Armstrong. Stepanek took the first set in a tie-break, Djokovic took the second in a tie-break and Stepanek is up a break in the third. Djokovic's serve is iffy, but he's showed no nerves on big points.
