Beleaguered Wimbledon organisers are confident of finishing on time after less than two hours of play was lost to the weather yesterday.

Rain has fallen on eight of the nine days so far and the tournament remains well behind schedule.

The tournament was 177 matches behind after rain interrupted play on seven of the first eight days and no fewer than 142 matches were interrupted by rain.

But eight hours play was possible yesterday and, with a brighter forecast for today, All England Club officials are hopeful of concluding with the men's doubles final on Sunday.

The two remaining quarter-finals, between teenagers Ana Ivanovic and Nicole Vaidisova and Venus Williams and Svetlana Kuznetsova, will be held today, which is traditionally ladies' semi-final day. That means both semi-finals will be held over until Friday, enabling the final to take place as scheduled on Saturday.

Two of the men's quarter-finals will be held tomorrow, 24 hours later than planned, along with the four remaining fourth-round matches.

Defending men's champion Roger Federer will play his first match for six days when he meets Juan Carlos Ferrero on Centre Court today while the finalist from the bottom half of the draw will have to play on four successive days.

Several of the game's leading past and present players rounded on officials for their failure to order play on the middle Sunday.
