Tough for Tim at Masters Cup

Tim Henman starts his tough Masters Cup schedule tomorrow against Andy Roddick - and a win will cap a fine year for the British number one.

The 30-year-old reached the semi-final of the US Open and French Open - but his challenge in Houston seems just as difficult as landing a major title.

And Henman is taking nothing for granted, despite beating Roddick in their last two meetings. The top two from two groups of four go through to the semi-finals.
