Miami Masters Tennis - Simon Mundie
Rafael Nadal continues in his relentless pursuit of a first title this season as he takes on Andy Roddick in what promises to be a pulsating opening semi-final in Miami. The other semi takes place in the early hours of Sunday morning as Robin Soderling faces Tomas Berdych.
The women's final sees Venus Williams going head-to-head with Kim Clijsters and the betting suggests it could not be any tighter.
Let's hear what the BBC's tennis correspondent Simon Mundie expects to happen as we reach a climax in Miami.
