Watch Wimbledon semis online

You can watch the semi-finals of Wimbledon live on the web on Friday afternoon.

The BBC Sport website will have live video, audio and text commentary coverage of both semi-finals.

Tommy Haas faces world number one Roger Federer in the first semi-final, which will take place at 1300BST on Centre Court.

After that, there will be the battle of the Andys - Murray and Roddick. Murray is hoping to be the first British man to reach a Wimbledon final for 71 years.

However, Roddick - known as A-Rod - will not be an easy opponent, with one of the biggest serves in the game. He has already served 139 aces in the tournament so far.
