Leifels, whose only previous PSA Tour success was winning the Swiss Open in 1995, survived a close four-game match against Raj Nanda when he beat the Australian favourite 15-8 9-15 17-16 15-7. His opponent in the final will be Constantino Casas, the unseeded Spaniard who is celebrating his first appearance in a PSA final. After dismissing second-seeded Swiss player Andre Holderegger to reach the quarter-finals, Casas defeated Zimbabwean qualifier Jesse Engelbrecht 15-12 15-10 15-7 in the other semi-final. The breakthrough star of the women's event was 19-year-old third seed Laura Lengthorn, twice a British Junior champion from Lancashire, who reversed last year's semi-final result to beat Scotland's defending champion Wendy Maitland, the No2 seed, 7-9 9-4 9-4 10-8. In her first WISPA World Tour final, Lengthorn takes on compatriot Suzanne Horner, the world No16 and double world Over-35 champion from Yorkshire who is playing in her first event since celebrating her 40th birthday. Top seed Horner, more than twice her final opponent's age, beat last year's runner-up Rebecca Botwright, the fourth seed also from England, 9-0 9-2 9-0 in the other semi-final.
