World No. 3 Rafael Nadal headlined a one-day exhibition tennis event at the newly-renovated Margaret Court Arena in Melbourne Park on Jan. 14. Nadal faced three opponents in separate matches in front of 7,500 crowd for the benefit of the Rafa Nadal Foundation, which aims to provide assistance for socially-disadvantaged people, and the Australian Tennis Foundation.

Fast4 or Disco Tennis is a faster version of the traditional tennis game that features tweaks in the official rules of the game. The new set of rules includes play lets, no advantage scoring, and tiebreaker at three games all. Lastly, the last rule is that the first player to win four games wins, hence the name, Fast4.

According to Tennis Australia, the format was introduced to speed up the action not only for the players but also for the fans. "Designed with the time-crunched player in mind, the Fast4 format means that anyone, anywhere has time for tennis. In short, Fast4 provides a simple, exciting way of speeding up a conventional tennis match."

Nadal first played against former U.S. Open champion Mark Philippoussis. He defeated the retired Aussie player, 4-1, in just 15 minutes. Then Nadal thrashed the reigning U.S. Open Junior champion Omar Jasika, 4-1, in only 17 minutes. Nadal concluded that exhibition event by winning against fellow compatriot Fernando Verdasco in a best-of-five sets match, 2-4 4-3 4-3 3-4 4-2.

"It's a great evening for a good cause," Nadal said after the matches. "We're trying to help as many kids as possible and without the support of Australian Open and without the support of all the crowd, it wouldn't be possible so I can just say 'Thank you very much everybody,' it has been a very special evening."
