To that end Harrington has committed to a Woods-like regime of training and diet. He even has midnight sessions hitting balls on the floodlit practice hole built into the garden of his home in Ireland.
Harrington said: "The harder you work the more you're going to get out of this game. The key is I enjoy doing the practice and the work. Work has never been a chore for me.
"I also used to be a lot heavier than I am now. I would eat all the puddings and pies. But these are the sacrifices you've got to make. It all leads to winning Open trophies."
Harrington, having overcome a wrist injury that last week threatened his participation at Royal Birkdale, retained the Claret Jug with a stunning last round of one-under-par 69 for a tournament total of three-over-par 280 that Norman, the third-round leader, simply could not match.
Despite being cheered on by new wife Chris Evert, Norman, 53, could not come to terms with the winds and faded to share third place with Sweden's Henrik Stenson.
