Chapman, 124^th in the World Squash Rankings, had earlier beaten Luke Butterworth of England in the first round. Having lost the first game, Chapman took the next 3 to progress with a 4 set, 8-11, 11-3, 11-3, 11-6, victory.

However, Grayson ended Chapman’s run with an 11-6, 11-2, 11-3 win in straight sets. “Thanks everyone for all your support. I lost 3-0 in the quarter finals, but had a great time in Houston. My focus is now on my next tournament in Las Vegas in two weeks,” commented Joe after the defeat.

Struck down with food poisoning and unable to last out the first game, top seed Julian Illingworth was forced to hand victory to Lewis Walters in the quarter-finals of the Houston Open at Life Time Fitness in Houston.

With match completed at 10-10 (ret.), the Englishman becomes the only unseeded player in the semi-finals of the PSA World Tour Challenger 10 tournament - the seventh event of the year in the new US Pro Squash Series.

"Semi finals of the Houston Open tomorrow," tweeted Walters. "However, not the way I would have liked to get there. I wish Julian a speedy recovery," added the 25-year-old from Nottingham.

Walters will meet Grayson and the other semi-final will pitch fourth-seeded Mexican Cesar Salazar against England's No2 seed Joe Lee. Cesar recorded his third successive Tour victory over his twin brother Arturo Salazar, winning 11-5, 12-10, 11-8 in 40 minutes.

Chapman had failed to reach the first round in his previous tournament, having to go through the qualifiers at the Northern Ontarion Championships earlier this month and not progressing.

For his next Tournament, Chapman will be heading off to Las Vegas for the Nevada Open.
