England's Suzie Pierrepont pulled off one of the best wins of her life when she beat third seed Isabelle Stoehr in the opening round of the Women's National City Burning River Classic to reach the quarter-finals of the $27,300 WISPA World Tour squash event at Cleveland Racquet Club in Cleveland in the US state of Ohio.

Stoehr, the 11 times French National champion, started well to win the first game.  But the usually fluent world No19, runner-up twelve months ago, became increasingly unsettled as the match progressed.  Unseeded Pierrepont, by far the tallest player in the draw, was the benefactor and put in a solid performance with very few errors. 

The 23-year-old from Sussex - still fighting back to recover the ranking loss since injuring her heel late in 2006 - ran away with the third and fourth games to record her impressive 5-9, 9-5, 9-2, 9-2 upset.

Ireland's Aisling Blake also upset the form book.  The 26-year-old from Sligo fought back from a game down to beat New Zealand's sixth seed Louise Crome - a practice partner at the Amsterdam club where they are both based - 2-9, 9-1, 9-7, 0-9, 9-4.
