BRISTOL, England -- American Roger Knapp, who says he would rather run an orphanage than play full-time professional tennis, Thursday knocked out top seed Henri Leconte of France to reach the quarterfinals of the $117,000 West of England grass court championships.
Knapp, who beat Leconte 6-4, 6-2 and 15th seed Peter Doohan of Australia in qualifying matches Thursday, next takes on another American qualifier, Glenn Layendecker.
Layendecker Thursday defeated Bud Schultz of the U.S. and Nduka Odizor of Nigeria.
The other all-American semifinal will be between eighth seed Marty Davis and sixth seed Brian Teacher, last year's runnerup.
It was a busy day Thursday with two rounds being played. In addition to top seed Leconte being dismissed, No.2 seed Terry Moor of the U.S. was also knocked out, losing 6-4, 5-7, 6-4 to Britain's Jeremy Bates.
Bates was then beaten in a 2 hour battle against Davis 4-6, 7-5, 9-7.
Knapp, 24, of Des Moines, Iowa, had never won a Grand Prix match before his 6-3, 7-6 first round win over South African Danie Visser earlier in the week. He had just returned to the pro circuit after taking two years off to study at a Baptist bible college.
'I returned to the circuit refreshed both mentally and physically,' Knapp said after what he described as the best win of his life.
'Now I am enjoying seeing just how far I can go in tennis. I don't want to make a ton of money, just enough to help me set up an orphanage back home. That is what I really want to do.'
Leconte, ranked 27th in the world and a quarterfinalist in the recent French Open, seemed to find all sorts of problems adjusting to Knapp's big left-handed serve andvolley game.
Tim Wilkison, the No.3 seed and Larry Stefanki, the No.5 seed were also eliminated Thursday. Wilkison was defeated by Odizor 6-4, 6-4 and Stefanki went down 7-6, 6-2 to Doohan.
Layendecker, better known as a doubles player, then defeated Odizor 6-3, 6-4 to set up his semifinal against Knapp.
