I think it was an awful move from the organizers to bring these stupid wannabe ball girls, the amount of mistakes they make is just.. And it was a crucial point of the match, and Fed went 0-30 on Kiefer's serve. I think it's annoying to the players.
Indeed. It IS a stupid move.
At least this incident was pretty funny. Earlier on during the tournament I saw several players being slightly annoyed with those toothpics pronking around - Nadal comes to mind.
Tennis is a SPORT, not a circus or a fashion show. Though I realize that Roger might like that second aspect.
