Ireland`s Shane Lowry birdied the 18th hole for a four-under 66 in the fourth round as he beat Bubba Watson by two strokes to claim the WGC-Bridgestone Invitational on Sunday.
It marked the first victory for Lowry since 2012 as he became the first non-PGA Tour member to win a World Golf Championship event since 2011 when Germany`s Martin Kaymer did it.
Lowry sank four birdies including a 15-foot putt on the 72nd hole to finish with an 11-under 269 total in the final tune-up before the PGA Championship at Whistling Straits.
American Watson matched Lowry`s 66 on Sunday but finished two strokes back with a nine-under 271.
It was another disappointing finish at the Firestone Country Club for American Jim Furyk who finished in the top 10 for the 10th time but is still seeking his first WGC-Bridgestone victory.
Furyk fired a two-over 72 and tied England`s Justin Rose (72) for third place, four strokes back of Lowry.
