Padraig Harrington and Caddie Ronan Flood
In a match of big-name heavyweights, Ogilvy didn't need to play his best to beat the Irishman. Ogilvy, a two-time winner in this event, was 3 up through nine holes even though he had just one birdie on his card.
Harrington, meanwhile, failed to produce a birdie all day as he bowed out in the first round for the third consecutive year.
"Paddy didn't have his best today," Ogilvy said. "He let me off the hook." Ogilvy essentially sealed the deal with an eagle on the par-5 13th when he rolled in a putt from 13 feet. That put him 4 up, and with Harrington unable to generate anything positive, Ogilvy strolled to the finish.
