FORT WORTH, Texas (AP) — Adam Scott was a late entry into Colonial because he wanted to play while ranked No. 1 in the world.
Scott will stay on top after a comeback victory at Hogan's Alley. He made a 7-foot birdie putt on the third hole of a playoff Sunday to beat Jason Dufner.
"It's so satisfying in so many ways to get it done," Scott said. "It's a good feeling, and maybe some validation."
Only days after officially overtaking injured Tiger Woods at No. 1, Scott bogeyed four of his first nine holes in the first round at Colonial. Midway through his final round, Scott had a double bogey that dropped him three strokes off the lead.
"Maybe added a little pressure for myself, trying to play like a No. 1. But I think the important thing was I realized that didn't mean playing perfect, and I certainly didn't play perfect all week," Scott said. "But the way you come back and get it done, and I felt like I certainly played like one of the best players in the world out there on the back nine."
The Australian certainly did in with consecutive birdies in the playoff.
The major champions parred No. 18 to start the playoff before matching birdies at the 17th hole. Dufner, who won the PGA Championship last year, hit his approach pin high on 17 to 4½ feet, but 2013 Masters champ Scott drained a 14-foot birdie before Dufner putted.
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 7-footer for his 11th PGA Tour victory, 5½ weeks after the 33-year-old Scott got married.
"It's tough to beat him. He's a great player. It's tough to concentrate, he's so good looking, too," Dufner said. "I thought maybe I could sneak one in there on 17, but he topped me."
Scott and Dufner both shot 4-under 66 to finish at 9 under, the highest winning score at Colonial since 1999. They started the final round part of a seven-way tie for 11th place, but only two strokes behind a quartet of leaders.
To stay No. 1 in the world ranking, Scott had to be in the top 13 at Colonial after Henrik Stenson finished in a five-way tie for seventh place in the BMW PGA Championship at Wentworth.
The win at Colonial, which came with $1,152,000 and a plaid jacket, made Scott the first player to win all four PGA Tour events in Texas. He is the 15th to win both the Byron Nelson Championship (2008) and the Colonial in the Dallas-Fort Worth area.
