Padraig Harrington holds a two-shot lead ahead of the final round of the ISPS HANDA Senior Open at Sunningdale. The three-time major winner carded a second successive 65 to leave him at the top of the leaderboard on 13-under par, two strokes clear of American Justin Leonard. Harrington has been battling with his game all week and revealed on Friday that he had to overcome a string of bizarre distractions while riding his luck in the second round. He still managed to card a bogey-free 65 on Friday and followed that up with the same number today with just one blemish on his scorecard for the day. “I still wasn’t comfortable,” said Harrington, who has scrambled well all week. “I thought I was getting better, but I don’t think I rode my luck as much today. I wasn't out of position, but I certainly didn’t play much better than yesterday. Maybe a little bit more cautious today.” Despite not feeling comfortable with his swing, Harrington is trying to focus solely on his scoring. "I don’t feel very good about how I’m hitting the ball, so trying to get away from that and not worry so much about that because clearly I’m scoring well,” he said. “You’re better off shooting 13-under par and not feeling so good about it than thinking you’re swinging it great and being level par. “So I just need to go out and play and try golf tomorrow. Hit the right shot at the right time and not necessarily try and play swing.” Should Harrington win tomorrow, he will join an elite group by becoming just the fifth player ever to win the Open and Senior Open after Gary Player, Bob Charles,Tom Watson and Darren Clarke “I’m not going to think about that,” he said. “Those are the sort of things that are getting ahead of yourself, and I'll wait till tomorrow to try and digest that.”
