Willstrop is the reigning British champion

Third seed Willstrop had to fight hard before edging out qualifier Darryl Selby and now faces Beachill, who beat Shahier Razik in straight games.

Eighth seed Grant also had to battle, seeing off Renan Lavigne of France after a 75-minute five-game struggle.

Top seed Thierry Lincou beat Australian Aaron Frankcomb in four games.

Lincou now plays Grant, who is determined to make an impression in his home-town event.

"I have lots of family, friends and supporters here to encourage me," said the 26-year-old left-hander.

"I want to put on a good show on the glass court but I know it will be difficult because Lincou is one of the toughest guys around."

Grant, the first black player to compete for England, added: "He's so accurate and so clinical, he makes it difficult to get into your stride.

"I need to make sure that I concentrate throughout the whole match and not go walkabout like I do sometimes.
