He took membership of the PGA Tour in 2005 and in March he won his first PGA Tour official money event at the Honda Classic, where he beat Vijay Singh and Joe Ogilvie in a sudden-death playoff.

Two weeks later his father died from oesophageal cancer on 11 July, the Monday night preceding the 2005 Open Championship, forcing Harrington's withdrawal.
