Andy Roddick faces Roger Federer for the 21st time, and there are some key facts and tips to consider before placing a Wimbledon men's final bet.

Firstly, Andy Roddick doesn't have the best record against Roger Federer, suffering defeat on 18 of the 20 times they've played. However, Roddick's most recent win came last year in Miami, where he beat Federer in three sets.

This Wimbledon final will be the third time Roddick and Federer have face each other in the wimbledon final. Importantly, Federer defeated Roddick in the 2003 and 2004 Wimbledon finals, with Federer being just too strong fr the American.

Another important fact that punters should consider is that Roddick's game does not match up well against Federer's. Aside from the psychological advantage of having beaten him 18 times, Federer's return shot selection becomes a powerful weapon which he employs against Roddick.

Federer is able to handle the pace of Roddick's serve, Roddick's biggest weapon, largely due to the fact that the American does not hit with much spin.

The good news for Roddick is that very few people in the tennis world gave him a chance to beat Andy Murray in the semifinals and in response Roddick played perhaps the match of his life to get to the final.

Expect another good match on Sunday. Roddick has managed to take at least a set from Federer the last two times they've played.
