It was not only the best score ever on the Copperhead Course at the Innisbrook Golf Resort but also Harrington’s career best.
His blemish free round included a 75-foot putt for birdie at the par-3 17th hole.
“I would like to tell you it was funneling right up the green and couldn’t go anywhere else, but certainly the last 15 feet it was right in the middle of the hole,” Harrington said.
The Irishman is a three-time major winner who has been relatively quiet in recent years, with his last win at the 2010 Johor Open on the Asian Tour.
“I’m very comfortable where my game is at,” he said after his round today. “I’ve made a lot of good improvements and I feel like things are ready to happen. Obviously today it showed the potential. Today is a peak.
“We will wait and see what happens over the next number of weeks. I’m trying to stay patient. I know my game is good. One of the hardest things is to wait with confidence.”
Harrington’s last win on the US PGA Tour was the 2008 PGA Championship and his other major victories were the 2007 and 2008 British Opens.
American Will Claxton was alone in second place in Florida after his opening round 7-under while Australia’s John Senden continued his good form to be equal third on 5-under along with US golfers Cameron Tringate, Kenny Perry, Jason Dufner, William McGirt, Jason Bohn and veteran Jim Furyk.
Jason Day and Robert Allenby were still in touch on 2-under with Greg Chalmers, Matt Jones, Nick O’Hern and Stuart Appleby a stroke further back. Rod Pampling and Marc Leishman were on even while Geoff Ogilvy really has his work in front of him after signing for a 1-over 71.2012 Transitions Championship Leaderboard
