Without wishing to offend either of them, it was a battle of two real sluggers.

There were very few subtleties in the game as they matched power for power, but what a game.

Jennifer eventually managed to wear Serena down, but the younger Williams sister had her chances, serving for the match.

Jennifer left it a bit late but she will be very relieved to have that match out of the way.

She will not have an easy task in the semi-final, though, after the way Justine Henin progressed on Court One.

The young Belgian was up against a very experienced player in Conchita Martinez, but she showed that she has got plenty of ability when it comes down to the crunch.

Henin has an unbelievable backhand, certainly the best one-handed backhand in the women's game at the moment.

But I would have to go for Capriati over Henin in the last four, just because of her extra experience in such a big-game scenario.

I'm sure that it favoured Tim more than Todd for the game to be carried over in to Tuesday.

Tim produced a much improved performance and he will be glad to have got a difficult opponent out of the way.

The physical aspect of having to play while others had a day off will not have had a great effect, but mentally it takes it out of you.

I remember a time when I was married to Chris (Evert) and she beat Martina (Navratilova) in a semi-final that had been played on a Friday instead of the normal Thursday because of the weather.

People were calling her up and congratulating her on her victory but when she went out the next day and played Yvonne Cawley she produced a flat performance.

Emotion can have an effect but, while it might give Roger Federer a slight advantage, I think Tim can still win through.

Lets hope so anyway.
