Open win has had major effect on Harrington

Open champion Padraig Harrington insists his triumph at Carnoustie revitalised his competitive nature and made him determined to work harder to ensure a repeat is not too far around the corner.

The 36-year-old Dubliner is refusing to rest on his laurels after becoming the first Irishman to win the Open in 60 years after edging out Sergio Garcia in a four-hole play-off last July.
