James Blake downs 15-year-old Ryan Harrison

Ryan Harrison shows his frustration by tossing his racket after losing a game while serving against James Blake during the second set.

Boy, you gotta keep that cool. Know what makes Rafael Nadal a champion? By being discipline and never toss or throw that racquet. You gotta respect your weapon.

Yesterday, top-seeded James Blake beat Ryan Harrison 6-3, 6-2 to move into the quarterfinals in the U.S. Men's Clay Court Championship. In just 50 minutes, Blake eliminates the Texas teenager, who earlier this week won his first-ever tour match. Harrison is only the 11th player since the Open Era began in 1968 to win a main-draw match at 15.

What's Roger Federer wearing?

I can't help but crazy over this yellow and white t-shirt worn by Fedex recently during a training session at the Estoril Open.

This Nike Co-[Lab] Tee is a 100% cotton round neck tee shirt featuring a graphic print by guest artist Misha Hollenbach of Perks & Mini from the 'Running Man' Co Lab collection. There's an embroided Nike logo on the hem.

It's also available in brown colour.

By the way, at the Estoril Open, Fedex is getting help from 55-year-old Spaniard clay court specialist, Jose Higueras who has helped guide Michael Chang and Jim Courier to Roland Garros crowns. So, I'm kind of nervous for Nadal this season.

Chance to lick Serbian tennis stars

The Serbs are taking their participation very seriously in the tennis event at the Beijing Olympics. I would say that they do stand a better chance to win gold medals compare to any other countries.

To kick off the Olympics campaign, top tennis players Ana Ivanovic and Jelena Jankovic have received the honor to be featured on first day covers and stamps as well as their male colleagues which include Novak Djokovic, world No.41 Janko Tipsarevic, and world No.6 doubles player and Australian Open mixed doubles champion Nenad Zimonjic.

The images for these five stamps were created by academic painter Marina Kalezic.

Surprisingly, I couldn't find Jelena's first day cover on the Internet at all.
