^^ You mean you think there being a tennis ball in his left pocket is 'hot'?
Ummm....yeah. Look again. He is holding tennis balls in his left and the bulge in his pants is smaller (though still hot)
than a tennis ball. Plus, I play tennis and there is a HUGE difference in a bulge from a tennis ball vs. the real bulge AND when you see djokovic playing he always carries the ball in his pocket on the left side of his thigh, not towards the middle. This bulge is towards the middle.
