Padraig Harrington's British Open success has shaken 2005 US Open champion Michael Campbell out of "sleep mode" and given him the urge to win more majors.

Campbell, who has slumped to 124th in the world rankings, said he had lost his competitive edge since holding off Tiger Woods to claim his maiden major but watching his friend Harrington at Carnoustie last month has proved an inspiration.

"I've been a bit tame for the last two years, my major win has lingered on too much and it's time to start working again," Campbell told reporters at the Kennemer course yesterday where he will play in this week's Dutch Open.

"Padraig and I had a discussion and I told him my lifetime goal had been to win a major. When I'd done it my mind and body went into sleep mode. Talking to him, and his ambitions to win more majors, I reassessed my own goals. Now I don't want to be a one-hit wonder, I want to be a multi-major winner.

"Resetting my goals has helped rekindle the fire in my belly and that's through watching my mates win majors."

Campbell plays the first two rounds of the Dutch Open with champion Simon Dyson of Britain and home favourite Maarten Lafeber, the 2003 winner.

Former three-times champion Bernhard Langer, who turns 50 on Monday, will play in the same field as his 17-year-old amateur son Stefan. After recovering from kidney stones, which forced him to withdraw from the Players Championship in Hamburg last month, Langer said he was raring to go if not yet fully fit.

Stefan, a scratch handicapper, plays on the Florida Junior tour and won the Del Webb Father-Son Challenge for major champions and their sons with Bernhard in 2005 and 2006. Langer does not have high hopes for his son at the difficult North Sea links. "I don't expect him to make the cut, to tell the truth, as it is such a tough golf course."

John Daly withdrew with a minor injury after missing the cut in last week's Scandinavian Masters.

Irish interests lie with Damien McGrane, Gary Murphy and David Higgins.
