Ammerlaan lost the first set before recovering

Norfolk, the world number six claimed a second win in the space of ten days over Wagner, winning 6-2 6-2.

The Hampshire player is now guaranteed to take over from Mark Eccleston as British number one.

He will face world number one Nobuhiro Tachibana of Japan in Sunday's final after he came from a set and 3-0 down to beat Bas van Erp of the Netherlands in his semi-final.

But there was disappointment for Norfolk when he and Eccleston lost in the semi-finals of the quad doubles.

There was also drama in the men's singles last four where Japanese third seed Satoshi Saida won four games in a row to take the first set 6-4 against world number two Robin Ammerlaan.

But the rear axel on Saida's tennis chair broke at the start of the second set and he had to borrow a chair to complete the match.

However the disruption affected Saida's concentration and he eventually lost 4-6 6-2 6-0.

Ammerlaan will meet world number one and defending champion David Hall in the final after Hall saw off Tadeusz Kruszelnicki of Poland 6-1 6-0.

The Dutch player has another chance for glory on Sunday when he partners Britain's Jayant Mistry in the doubles final against Hall and Michael Jeremiasz of France.
