For 15 holes Tiger Woods and Padraig Harrington dueled for the WGC-Bridgestone Invitational until a triple bogey on 16 ended any chance of victory for the Irishman.
Harrington started the day three shots ahead of Woods, but that lead evaporated when Woods started his first four holes par/eagle/par/birdie.
Woods had two more birdies on the front nine to go to 12 under par, while nine straight pars from Harrington saw him make the turn two shots behind.
Harrington got a birdie on 11 to close the gap to one and consecutive bogeys for Woods on 13 and 14 saw the Irishman take the lead by one.
Both men parred the 15th and hit wild tee shots on the par five 16th hole. Woods hit to the left and punched his second on to the fairway while Harrington went right and punched his second on the lip on a fairway bunker.
Woods hit his third to inside a foot, while Harrington hit his third over the water and into the rough at the back of the green.
Harrington's fourth shot at the 16th ended his tournament as he overhit his pitch shot, put it straight into the water and had to take a penalty stroke.
He hit his 6th shot to the back of the green again and ended up with a triple bogey 8, effectively ending his challenge as Woods tapped in for birdie and a three stroke lead with two holes to play.
Harrington parred the last two to card a two over par 72 and end in a tie for second with Robert Allenby, while Woods finished with a birdie on the last for a five under par 65 for a total of 12 under par and a seventh WGC –Bridgestone Invitational title.
Though undoubtedly gutted with how his round imploded on 16, Harrington has hit form at the right time ahead of Thursday’s defense of his USPGA title at Hazeltine.
Here's hoping he can shake off the disappointment of the triple bogey on the 16th before the year's final major.
