Triple major winner Padraig Harrington, helped by three consecutive birdies after the turn, held off a last-day charge by U.S. Open champion Webb Simpson to win the PGA Grand Slam of Golf in Bermuda by one shot on Wednesday.
Irishman Harrington, a late addition to the elite four-man field, fired a four-under-par 67 at Port Royal Golf Course in Southampton for a nine-under total of 133 in the 36-hole event.
Two strokes ahead of Masters champion Bubba Watson overnight, Harrington mixed five birdies with a lone bogey at the par-four last to fend off American Simpson, who closed with a best-of-the-week 65.
It was the 41-year-old Irishman's first victory since the 2010 Iskandar Johor Open on the Asian Tour.
"It feels good. I haven't won in a while. Winning is a habit and it's nice to do it," Harrington said. "I believe that there's good stuff in my game."
