• Video: Check out Marion Bartoli's wacky training regimen. Hey, it works. She's already built a 4-0 lead on Sharapova in their quarterfinal match.

• George Vescey on U.S. Open night tennis. There's nothing like it.

Under a pulsating full moon, the gussied-up Billie Jean King National Tennis Center seems much softer and prettier at night, with the fountains bubbling and fans without tickets to the big stadium sitting in the plaza and watching a big screen. Men in suits and women wearing jewelry and dresses and high heels stride toward the luxury boxes. And the stars take the aura as their due.

• Peter Bodo looks at the unexpected all-Italian quarterfinal between best friends and doubles partners, Sara Errani and Roberta Vinci.

“I have a difficult style of tennis, for sure, different style. I mix a lot of balls. I go to the net. I play a lot of slice. So it's different. So probably she (Radwanska) doesn't like my slice. Also when I go to the net, probably her passing shot is not so good. That's why I won today probably. This is the key.” Imagine, a WTA player challenging a rival to hit pin-point passing shots instead of allowing her to merely whale away at the ball, aiming it vaguely to either the forehand or backhand territories in the backcourt!

• David Nalbandian will skip Davis Cup due to the same rib injury that kept him out of the U.S. Open.

• Novak Djokovic is running silent, running deep.

Djokovic's status as a near afterthought nearly halfway into the tournament's second week is even more amazing when you consider Djokovic is still the No. 2 player in the world, Rafael Nadal isn't here to siphon off his usual share of attention and -- most interesting of all -- just the other day, the great Roger Federer himself volunteered that when he stepped up at 5-3 to serve out his otherwise-unremarkable straight-set trouncing of Fernando Verdasco, he had a flashback to the mind-blowing crosscourt service return Djokovic used to save a match point against him in last year's U.S. Open semifinal.

• Tennis Channel has some great interviews up on their site, including chats with Kim Clijsters, Roger Federer and Ana Ivanovic. Be sure to check out this video essay on Andy Roddick by SI's Jon Wertheim.
