Ireland's Padraig Harrington began the Transitions Championship in Florida with a dazzling course-record ten under par 61, the lowest round of his career.
Down to 90th in the Official World Golf Ranking, Harrington held an early five stroke clubhouse lead on his return to action after failing to qualify for last week's World Golf Championships event.
The three-time Major winner started with back-to-back birdies at Innisbrook, finished with three in a row and had five more in between.
American Kenny Perry, now 51, was Harrington's closest challenger out on the course. With three to play the former Ryder Cup player stood six under.
