Rafael Nadal is going to win Wimbledon on Sunday and prove once again that he is the top player in the world.
I am predicting that Rafa will win in four sets over Berdych. Berdych has had a great run and is definitely someone to watch out for in the future, but Rafa's experience will be the difference.
With the win Nadal will strengthen his lead over Federer and Djokovic. On top of that Nadal doesn't have a lot of points to defend the rest of the year.
What makes Nadal special is his ability to play on different surfaces and change his game. Nadal has been coming into the net more and more throughout the tournament. And he's shown he can be a very good good volleyer.
He can still dominate from the back of the court, but he's improved his serve as well. Nadal hasn't been broken very often in the tournament and with his return game that makes him very dangerous.
If he wins Wimbeldon he will have one more big step to take to show that he can be one of the best of all-time -- win the U.S. Open. It's the only grand slam that's eluded him, but I think it's very much within his grasp. The key for him is to stay healthy. He's already said he will take same time off after Wimbledon, which I think is a very good idea. He needs to rest some after the long clay/grass court seasons and then gear up for the U.S. Open.
I think he can and will win the U.S. Open as well and if he does that would give him 9 slams already and he would have a career grand slam. Once again the key issue for Nadal is staying healthy, but if he can there's no reason to think he can't eventually challenge Sampras' and Federer's numbers for grand slam titles.
