Rory McIlroy and Chris Gotterup get under way in one minute. After driving into a bunker he has a chance to save par from inside five feet but can't take it. Frustration for the American. The penultimate group of the day have just teed off at the first.

Mouw won when third-round leader Paul Peterson — who was playing the 10th hole at Hurstbourne Country Club when Mouw finished — missed a 55-foot birdie try from the front fringe on the par-4 18th. Mouw won in his 20th start on the PGA Tour.

Rory McIlroy shares the lead at the Genesis Scottish Open and says he's nearly back to his Masters-winning form.

American Chris Gotterup impressively holds off Rory McIlroy and the chasing pack to claim the biggest win of his career with a remarkable Scottish Open success.

Gotterup, built more like fellow New Jersey athlete Mike Trout than a golfer, also won the opposite-field Myrtle Beach Classic last year. The Genesis Scottish Open had one of the strongest fields of the year, and the perks are far greater.
