Adam Scott made a seven-foot birdie putt on the third hole of a playoff Sunday to end his first week as the world’s No. 1 player with a victory at Colonial in Fort Worth.

Jason Dufner, who made a 25-foot birdie putt on No. 18 in regulation, slid a 40-footer past when he and Scott played the 18th hole for the second time during the playoff. Scott then made the seven-footer for his 11th PGA Tour victory.

The major champions parred the 18th to start the playoff, then matched birdies at the 17th hole. Dufner, who won the PGA Championship last year, hit his approach there pin high to 41 / 2 feet, but 2013 Masters champion Scott drained a 14-foot birdie before Dufner putted.

Scott and Dufner both shot 4-under-par 66s to finish at 9 under, the highest winning score at Colonial since 1999.

CHAMPIONS TOUR: In Benton Harbor, Mich., Colin Montgomerie won the Senior PGA Championship, finishing with a 6-under 65 for a four-stroke victory over 64-year-old Tom Watson.

It marked Montgomerie’s first victory as a senior, his first win in seven years and his first in an official event in the United States. The 51-year-old Scot also claimed a senior major in his fifth attempt, something he didn’t accomplish in 71 majors in his regular tour days.

McIlroy’s 12th victory worldwide comes four days after the 25-year old Northern Irishman confirmed the end of his engagement with Danish tennis star Caroline Wozniacki.

Shane Lowry of Ireland came in second with a round of 68 for a 13-under 275.
