World number one men's tennis player Roger Federer goes for his third straight Wimbledon men's tennis title Sunday when he takes on American Andy Roddick. The two players bring a contrast of styles to their second straight meeting for the Wimbledon men's crown.

Federer has beaten Roddick in eight of their nine matches. He is chasing his fifth Grand Slam crown and his 36th successive victory on grass.

The world number one has stunning ground strokes, big serve and sharp volleys all combined by speed and balletic movement as he glides across the court.

"I will look at the last two matches that I have played him here at Wimbledon but then also try to remember the other matches I have played against him what worked, what did not work. I think he came out hitting the ball extremely hard last year," he said.

Roddick has the fastest serve in the world his best 155-miles-per-hour (249 kilometers per hour) and a big forehand. He is very quick and he can hammer most players off the court.

Last year he took the first set from Federer. This time he aims to deliver a tougher challenge, but Federer is clearly the hot favorite.
