World Championship Tennis in Dubai

Federer after the win... (sorry camera on phone is a little blurry)

Federer on the left and Djokovic on the right

I got to attend the Dubai Championship Tennis Tournament last night and watch Roger Federer (current world rank #1) barely get past a 19 year old Serb named Novak Djokovic. It was a great match and it was particularly interesting to see the technology called "Hawkeye" employed.

I think players had 2 challenges per game or set (not sure which). When they suspected a ball was not called out/in correctly then they could signal the umpire. Then everyone in the stadium would watch as the course of the ball was simulated on the large screen and the place where the ball had landed was indicated. The video would zoom in to indicate whether some of the ball had indeed clipped the line to be called "in" or whether it had, in fact, fallen outside the line.

The second set was decided on a "hawkeye" challenge. It was a tie breaker and the supposed winner was called "in" for Federer. But the replay showed it was out and so the tie break went on and the Serb won it!
