England's Lauren Siddall claimed an unexpected place in the final of the Women's Internationaux de Creteil after upsetting second seed Tricia Chuah in straight games in the semi-finals of the $12,550 WISPA World Tour squash event at Centre Marie Therese Eyquem in Creteil, France.

The third seed from Pontefract in Yorkshire reached the semis after despatching compatriot Emma Chorley, a qualifier, 9-3, 9-3, 9-2. After surviving a close first game against Chuah, 23-year-old Siddall went on to beat the world No29 from Malaysia 10-9, 9-3, 9-1 in 34 minutes to earn her second appearance in a Tour final.

Siddall's opponent will be the new Dutch national champion Annelize Naude, the top seed who survived a stern test from compatriot Karen Kronemeyer in the quater-finals.

In more dominant form in the semi-finals, the 31-year-old from Amsterdam defeated France's European junior champion Camille Serme, the fourth seed, 9-4, 9-2, 9-1 to mark up her 12th appearance in a WISPA final.
