Can you give me some reasons as to why tennis is a tough sport? My brother, who is a football/lacrosse head, believes that tennis is not tough.
-- George, Auburn

Tell him to imagine the most tired he's ever been playing football or lacrosse. And then tell him to imagine feeling that way with no teammates to rely on.

Jankovic touches up her make-up (powders her nose) during changeovers. Is this an endorsement thing or just a girly thing?

I vote girly.

In the last Mailbag, we posed the question, which players have beaten both Williams sisters in a single tournament? Howie of Auckland, New Zealand, writes: "Arantxa Sanchez-Vicario, Sydney 1998, the first player to do so. (Coincidentally, one of the very few tennis trivia that I know from the top of my head)."

Then Roger Gatchalian, the Greg Sharko of the WTA Tour, sent us this:

Shots, miscellany

• From a reader who requested his name be withheld: "I volunteered as a player escort at the Indy tournament again this year (ohh, stories to tell), and when Roddick got off the court hungry at midnight on Friday, he weighed his options out loud. Unfortunately I believe he decided on the Taco Hell location still open downtown, no matter how we vols tried to dissuade him, knowing ourselves the sorry fare trotted out there."

• In case you missed it, this excellent piece on Jennifer Capriati is worth your time.

• Say this about Kim Clijsters, she wasn't lying when she said she was looking forward to having kids.

• Speaking of Clijsters, apparently her wedding pictures are posted on her Web site for those who are interested.

• Kenneth Quek of Kuala Lumpur, Malaysia, found this gem.

• After last week's Harry Potter confusion, let's be clear: the bit about Federer is a joke!

• Oliver of Trier, Germany, writes: "Wow, what a great future doubles team: Kittipong Wachiramanowong/Peerakiet Siriluthaiwattana of Thailand (both played in the juniors competition at Wimbledon this year)."

• Cyrena of Phoenix: "Not sure if you've seen this gem yet. As near as I can tell, Pau Gasol (Memphis Grizzlies) and Nadal have to compete to win some rather fine watches. It's best if I say no more (click here).

• Several of you suggested I link this column I recently wrote about cheating in tennis.

Norton

• DB of New York writes: In honor of Sampras' induction into the Hall of Fame, check this out.

• Graham Powell of Fort Worth, Texas, writes: "I thought you might be interested in this nice interview with Sampras that ran in the Fort Worth Star-Telegram."

• Mariya of New York City sends us this week's long-lost siblings: Christophe Rochus and Edward Norton.

Have a great week, everyone!
