FORT WORTH, Texas — Adam Scott, the world’s top-ranked golfer, defeated Jason Dufner with a birdie on the third playoff hole to win the Crowne Plaza Invitational at Colonial on Sunday.

With the win, Scott becomes the first golfer to claim the Texas Slam, winning all four events in Texas in his career. It’s the 11th win in Scott’s PGA Tour career. Scott won the Shell Houston Open in 2007, the HP Byron Nelson Championship in Dallas in 2008 and the Valero Texas Open in San Antonio in 2010.

Scott and Dufner both parred the first playoff hole, the par-4 18th. Then they each birdied the par-4 17th, with Scott rolling in a putt from 14 feet, 3 inches after Dufner knocked it close.

Scott then birdied from 7 feet back at the 18th for the win.

The victory comes the same week that Scott moved to No. 1 in the Official World Golf Ranking.

“This is really a special week for me,” Scott said. “… I was determined. I really wanted to win ’em all here in Texas.”

Both players finished at 9 under after 72 holes after shooting 4-under 66s in Sunday’s final round at Colonial. That was good enough to put them one stroke ahead of Nicholas Thompson and Freddie Jacobson.

The playoff was the 11th in tournament history and first since 2009 when Steve Stricker beat Tim Clark and Steve Marino.

Dufner reached 9 under thanks to his 25-foot birdie putt on his final hole Sunday. “I’m glad I hung in there and finally got one to fall inside on 18,” Dufner said.

Scott bounced back from a double bogey at the ninth hole with a bogey-free 3-under back nine.

“I just had to limit the mistakes on the back nine,” Scott said, “and I did a pretty good job of that.”

Scott has won all three of his playoffs appearances on the PGA Tour, including the 2013 Masters when he beat Angel Cabrera on the second playoff hole.

Dufner, who won the PGA Championship last year, is now 1-3 in playoff appearances. He won his first TOUR event in a playoff, beating Ernie Els at the Zurich Classic of New Orleans in 2012.
