2002 was another successful year on the European Tour with particular success towards the end of the season including winning at the Dunhill Links Championship in October, having birdied the final hole to get into a playoff with Eduardo Romero. This win and a further 9 top ten finishes earned Harrington a second-place finish on the European Tour's Order of Merit for the second consecutive season. This form earned Harrington a second Ryder Cup appearance at the 2002 Ryder Cup hosted at The Belfry, in the final day singles Harrington, playing in match 5, won an important point against Mark Calcavecchia helping Europe to victory and regain the cup by a score of 15.5 to 12.5.
