Harrington one shot clear

Padraig Harrington leads the field by one shot after two rounds of the World Golf Championship event in Ohio after a second round 69.

The Irishman led by two shots after the first round following an opening 64 and he followed that up with a one-under par round to sit on -7 and take a one-shot lead into the weekend. South African Tim Clarke lies second with Scott Verplank a further shot back on five-under at the halfway stage. Tiger Woods is far from out of contention and he sits on -2, alongside England's Oliver Wilson, and is in a good position to strike at the weekend. But three-time major winner Harrington holds all the aces after 36 holes and he admitted that he had erred on the side of caution after his scintillating opening round at the Firestone Country Club. "Shooting that score yesterday gave me a great chance for the tournament," he said. "Anything under 70 from here on in is going forward so I'm quite pleased to have shot 69. "I normally play the first rounds cautiously. I was a bit cautious today. I was more worried about my misses rather than having that sort of confident attitude and going after a few more pins. "You know that if you miss the green on the short side you're going to have difficulty getting up and down. But you've got to make some birdies. "My short game has been good enough, so I probably should be a little bit more aggressive over the weekend."
