THE US OPEN IS WARMING UP!
Here is a couple of photos of the caliente Rafael Nadal during a practice session at the 2009 U.S. Open in Flushing, Queens, New York City [INF]
And one of Russian Marat Safin, who also had to practice shirtless ... If the players do the practices shirtless, this means they are much more comfortable this way and should be allow to play during competitions like that! I am sure more people will suddenly find new interest in tennis.
