The German provided the story of the week by becoming the oldest player in more than 30 years to defeat a world No.1 when he beat Novak Djokovic in the fourth round, but Ferrer, the world No.5 from Spain, proved too strong over the course and won 4-6, 6-2, 6-3.

Haas, the former world No.2 who turns 35 on Wednesday, already had guaranteed himself a return to the top 15 next week, a remarkable achievement considering he was ranked No.145 this time last year.

The German's exploits caught up with him in the end against Ferrer, though. Haas led 3-1 in the final set before Ferrer showed his fighting qualities and fitness by winning the last five games to clinch a place in tomorrow's final.

The 30-year-old, who won his first Masters series title in Paris last November, now awaits the winner of Andy Murray versus Richard Gasquet, who met in the later match last night.

Meanwhile, Laura Robson continued her dream run in the doubles with the American Lisa Raymond as the wildcard pair upset the world No.1 duo, Sara Errani and Roberta Vinci, of Italy, 6-1, 6-2 in the semi-finals.

The pair only teamed up after Raymond's original partner, Sam Stosur, withdrew after pulling a calf muscle. Robson and Raymond share the same agent and a wildcard was arranged as Robson's doubles ranking of No.278 was too low to earn her direct entry.

Their performance this week has guaranteed that Robson will now enter the top 100 in doubles and Raymond, a former world No.1 who has won 11 grand slam titles, has been so impressed that she likened the Brit to a young Lindsay Davenport.

Judy Murray, the Great Britain Fed Cup captain, was also impressed as she watched from the stands with the World Cup Group 2 play-off away to Argentina coming up in three weeks.

"Laura really rose to the occasion, as she always does when she has the chance to play a big match on a big court," said Murray. "It doesn't faze her at all like it does for some of the younger players. She looks very happy, a lot of smiling, a lot of purpose, and this will do her a power of good ahead of the Fed Cup tie."

Robson and Raymond will tomorrow play third seeds Nadia Petrova and Katerina Srebotnik or Svetlana Kuznetsova and Flavia Pennetta.
