“Last winter (McDermott) set Australia’s young development squad a target of bowling 80 per cent of its deliveries on a full length,” Dymock said.

“They could only achieve 27 per cent.

“If nothing else, what he’s done with the Aussie bowlers is get them to pitch the ball up.

“It’s been a tendency of theirs to pitch the ball halfway down the wicket in recent years.”

Dymock, who mentored former Aussie bowler McDermott on his first tour of England, was at Bunton Park yesterday for a country cricket clinic, where he passed on his valuable bowling knowledge to the Border’s next crop of cricket stars.

He said his main aim was to correct the bowling action of kids so they didn’t suffer injuries later in their careers.

“What I’ve done so far is determine if the kids have a side-on, front-on or mixed action,” Dymock said.

“Then I’ll give them some tips to ensure they’re bowling properly and to make sure they avoid injury, which is becoming much harder these days.”

Dymock, who is one of just six cricketers to dismiss all 11 opposition batsman in a Test match, said he was blessed with a pure bowling action.

“Someone once asked me how I managed to bowl 27,000 balls in first-class cricket,” Dymock said.

“It’s because I haven’t ever had any injuries at all.

“It was probably luck because I never had any coaches or anything like that to tell me how to bowl.”
