I was watching the Andy Roddick - Novak Djokovic men's quarter-final (2-6, 3-6, 6-3, 7-6) at the 2008 US Open when I noticed something odd. After Roddick threw his racket to the ground to my astonishment a ball boy waited for the racket to stop bouncing and then promptly rushed to pick it up.
Are ball boys expected to pick up a player's racket after he or she throws it to the ground? I've never noticed this before and I wonder if this is a common or uncommon occurance. If a player is frustrated or angry enough to throw his racket, then the player should pick up his own beepin' racket.
