It was the second successive upset by the 19-year-old World Junior Champion from Pontefract who beat fourth seed Martin Heath, the world No10 from Scotland, in the previous round. In tonight's first men's quarter-final on the all-glass showcourt which staged the Commonwealth Games action last summer, Willstrop beat Taylor 15-7 10-15 9-15 17-15 15-9 in 87 minutes after almost throwing the match away in the third and fourth with a succession of unforced errors. "The third game was just horrendous," said the delighted 6' 5" tall youngster after his triumph in the longest match in the competition. "Nick managed to contain it all in the early part of the match. After the third, I decided to change my tactic and stay forward - I knew I just had to get back to playing my own game and when I did, things started to go right for me again." A disconsolate Taylor, a semi-finalist for the last three years who was playing his team-mate in the Manchester-Pontefract National League side for the first time, said: "I was really disappointed with my game - I got the tactics completely wrong and I felt the whole match was scrappy. But I can't take anything away from James - he played really well." Willstrop will meet top seed Peter Nicol in Saturday's semi-finals after the London-based world No1 beat 1998 champion Simon Parke in an all-Yorkshire clash. "I put Simon under a lot of pressure in the first game and, though he pushed forward in the second, I think I had done enough by then," said Nicol after his 15-7 15-11 15-8 victory in 50 minutes. "James and I have never played each other before so I'm looking forward to meeting him - even though I'm giving him ten years!" added the 1996 British National champion on the prospects of his semi-final encounter. Sussex's top seed Linda Charman and Essex's No4 seed Rebecca Macree will renew their rivalry in Saturday's semi-finals after straight games victories in tonight's women's quarter-final clashes. Charman, the 31-year-old world No4 from Eastbourne who is bidding to win her first title after three appearances in the final, ended unseeded Jenny Tranfield's run in the event, beating the world No13 from Yorkshire 9-3 9-5 9-0 in 36 minutes. Londoner Macree, boasting a career-high world No9 ranking, defeated Scottish No1 Pamela Nimmo, the world No16 from Edinburgh, 9-6 9-3 9-1 in 34 minutes. The remaining quarter-final matches will take place on Friday, starting at 6.00pm - featuring Lee Beachill (Yorkshire) v David Evans (Wales); John White (Scotland) v Alex Gough (Wales); Cassie Jackman (Norfolk) v Stephanie Brind (Kent); and Tania Bailey (Lincs) v Suzanne Horner (Yorks) Official website: www.nationalsquashchamps.co.uk
