FORT WORTH, Texas — Adam Scott made a 7-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.

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 7-footer for his 11th PGA Tour victory.

The major champions parred No. 18 to start the playoff, then matched 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 and Scott both shot 4-under 66 to finish at 9 under, the highest winning score at Colonial since 1999.

Former LSU golfer David Toms, who shared the lead after Saturday’s third round, shot a 70 Sunday to finish tied for fifth at 273, two shots off the pace.

Scott replaced the injured Tiger Woods at the top of the ranking last Monday and will stay No. 1. 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 Hogan’s Alley, which comes 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.

The 11th playoff in Colonial history was the first since 2009, and the longest since Jim Colbert beat Fuzzy Zoeller on the sixth extra hole in 1983.

Nicholas Thompson and Freddie Jacobson tied for third at 8 under. Thompson shot 66, a stroke better than Jacobson.

Toms, in the final group, led at 9 under when he made his turn. But he had three bogeys over the next five holes and finished with a 70.

Toms ended up at 7 under with Brendon Todd (68), who last week got his first PGA Tour victory at the Nelson.

Jimmy Walker, No. 1 in the FedEx Cup standings, shot a 70 and was among four players tied for 10th at 6 under.

About 30 minutes after Dufner made his long birdie at No. 18 to get to 9 under, Scott made a closing par when his 31-foot birdie chance — which would have wrapped up the victory — slid just past the hole. It was just less than an hour later when the two went back to No. 18 to start the playoff.

At the same time Scott was finishing, Toms was coming off a bogey at the par-3 13th that dropped him two strokes back.

Scott and Dufner started the final round part of a seven-way tie for 11th place, only two strokes behind a quartet of leaders that included Toms.

They were among 33 players within four strokes of the leaders when the day began.

Scott was 8 under after making a 6-footer at the 406-yard No. 6 hole, his fourth birdie in the round and already with a bogey at the par-4 third when he three-putted from 24 feet.

His only other three-putt at Colonial came from 17 feet at the ninth hole, dropping him to 6 under and three strokes behind Dufner.

But Dufner gave up a stroke when he missed a par putt from less than 3 feet at the straight 615-yard 11th hole. When his 12-foot birdie chance at the 440-yard 12th hole slid a half-foot past the cup, Dufner stood momentarily and stared at the ball before tapping in his par.

Scott caught up with consecutive birdies on those same holes, pitching to 9 feet at No. 11 before his approach at No. 12 to 4 feet.

Dufner had another near miss at No. 15, where another lengthy birdie chance slid inches by the hole.

When Scott made a 39-birdie putt at the 453-yard 14th hole, he was 9 under — then tied with Toms and one ahead of Dufner.

Champions

Montgomerie wins Senior PGA: In Benton Harbor, Michigan, Colin Montgomerie said he learned something about playing major championship golf at the age of 51 in the Senior PGA Championship at Harbor Shores.

“I learned today to concentrate on me, and possibly I haven’t in the past,” the Scot said Sunday after shooting a 6-under 65 for a four-stroke victory over 64-year-old Tom Watson. “We’re always learning, and today I concentrated on my own play and could only worry about myself.”

The victory was first as a senior, his first in seven years and his first in an official event in the United States. He also claimed a senior major in his fifth attempt, something he didn’t accomplish in 71 majors in his regular tour days.

Montgomerie, whose greatest moments in golf have been in Ryder Cup competition, finished at 13-under 261 for his first victory since he took the 2007 European Open for his 31st European Tour title.

Watson also closed with a 65, and Jay Haas and Bernhard Langer tied for third at 7 under. Haas had a 67, and Langer shot 70.

Montgomerie offered some comic relief on the final hole when he pulled his final approach some 20 yards only to get a bounce off the grandstand. The ball rolled to the middle of the green to set up a tap-in par.

“I feel fantastic, really, superb,” he said. “There’s a motto: ‘If you fail and fail, you come back and try again.’ I’ve had a couple of failures here in America and close calls, especially in major championships, and it’s great to finally win, never mind a Champions Tour event, but a Senior PGA Championship event.”

Watson, who later this year will captain the U.S. Ryder Cup team, put a charge in the tournament when he made birdies on the second and fifth holes and started the back nine with consecutive birdies to pull within one shot of the lead. He missed a 4-foot birdie putt at the short par-5 15th hole that would have put him within one shot again.

“Yeah that was the roadblock right there,” Watson said. “I needed to make four there to keep the pressure on.”

Montgomerie made a charge of his own. He birdied Nos. 8, 9 and 10 and, with precise iron shots and clutch putting, also made birdies at 12, 14 and 15 to pull away. He said the birdies in the middle of the round were the key.

“I was caught,” he said. “It was between seven or eight players that could actually win there. Those birdies were the key.”

Montgomerie will head home to Scotland for a few weeks with a first-place check of $378,000 and his name will go on the Alfred S. Bourne Trophy. The win also netted him a lifetime exemption to the Senior PGA Championship, and 2014 exemptions for the PGA Championship, Senior British Open and U.S. Senior Open.

Watson, who made a bid to be the oldest player to win a senior event of any kind, had five consecutive pars to end his round while missing several birdie chances. He hit 17 of 18 greens in regulation.

“It was one of the best rounds from tee to green that I played in years,” Watson said. “It was really, really good, but the putter felt like a snake in my hands. I missed a lot of short putts today. It could have been a much better scoring round of golf.”

Bernhard Langer, playing with Montgomerie for a fourth consecutive round, hit his tee shot at No. 11 in the hazard right of the green and ended up making double bogey on the 140-yard par 3. It put him four shots behind Montgomerie at the time.

Montgomerie is the third Scot to win senior golf’s oldest championship, and the first since Jock Hutchison won his second Senior PGA in 1940.

LPGA

Korda charges to Airbus victory: In Mobile, Alabama, Jessica Korda won her first LPGA Tour title two years in Australia and opened this season with another victory in the Bahamas. On Sunday, the 21-year-old Florida got one on her home turf with a back-nine charge in the Airbus LPGA Classic.

“It’s very sweet,” Korda said. “Finally on U.S. soil and somewhat close to Florida. I definitely wish that I could have at least shared it with my parents, but I know that they’re watching. My brother’s playing a tennis tournament right now and my sister’s trying for a U.S. Open qualifier, so we’re kind of scattered all over the place, but I can’t wait to go home and share this with them.”

Korda, whose father, Petr, won the 1998 Australian Open tennis tournament and mother, Regina Raichrtova, also played pro tennis, birdied four of the final five holes, making a breaking 15-foot birdie putt on the par-4 18th for a 7-under 65 and a one-stroke victory over Anna Nordqvist.

Korda played the back nine in 6-under 30 to finish at 20-under 268 on The Crossings course at the Robert Trent Jones Golf Trail’s Magnolia Grove complex.

“It just sets up great for my game,” said Korda, who shot 20 under in this event last year and tied for second. “I can be aggressive. I can read the greens. My confidence just was rising every single day. I just love it here. I love Alabama, I love this golf course, and hopefully we’ll have this tournament for a very, very long time.”

Nordqvist also birdied the 18th and finished with a 69.

Michelle Wie, 18-year-old Charley Hull and 44-year-old Catriona Matthew tied for third at 18 under. Wie and Hull shot 67, and Matthew had a 69.

Wie played alongside Korda and Hull.

“I love playing with Korda,” Wie said. “It’s also really great playing with Charley as well, too. You feel old but it was a lot of fun.”

Wie, the winner last month in Hawaii, has seven top-10 finishes in 10 starts this year.

“I knew I needed a low score,” Wie said. “I got hot starting on and just didn’t quite get it together on the back nine, but still I shot 5 under today and there’s really nothing I can do. I’m just really happy for Korda. I had a lot of fun playing with her and I knew I needed a low number and I just didn’t hit it low enough.”

Korda started the day three strokes behind 54-hole leader Nordqvist and managed only one birdie on the front nine.

“Yesterday was a little frustrating because I was always around the hole and same thing actually on the front nine, watching Michelle make putt after putt after putt and mine were just kind of missing,” Korda said. “I was like, OK, it’s time to drop now. Then they started dropping on the back nine. It was a really relaxed day, so I really enjoyed the walk.”

She birdied Nos. 10 and 12 to join a six-way tie for the lead, with three more players just one shot off the pace in the birdie-fest.

“Charley was making birdies, Michelle was making birdies and everybody behind us was making birdies, so I knew I had to keep making birdies,” Korda said.

Korda broke out of that logjam with a curling downhill birdie putt at the 14th hole, then took the lead for good with a 25-foot birdie on No. 15.

She protected that small lead with a birdie at the par-5 16th and her closing birdie on the 18th.

“That last putt broke really hard,” Korda said. “I probably played it about a yard out and I was just trying to get it down there close and it went in. I have not played well since I won in the Bahamas but I’ve been working hard and it finally paid off here.”

Second-ranked Stacy Lewis had a 71 to tie for 10th at 15 under. She needed a solo third or higher to take the top spot in the world from Inbee Park.

PGA Europe

McIlroy takes BMW title: In Virginia Water, England, Rory McIlroy put aside the anguish in his private life to win the European Tour’s flagship BMW PGA Championship on Sunday.

The double Major winner came from seven shots back at the start of the final round to shoot a 6-under 66 and win by 1 stroke with an overall 14-under 274 on the Wentworth course.

It is McIlroy’s first European Tour success since December 2012 and also ends a run of eight second-place finishes in 11 events this season.

McIlroy’s 12th victory worldwide comes four days after the 25-year old Northern Irishman confirmed the breakdown in his relationship with Danish-born tennis star Caroline Wozniacki.

Ireland’s Shane Lowry birdied the last hole for a 68 and finished second on 13 under.

Smith wins Rex Hospital Open: In Raleigh, North Carolina, Byron Smith won the Rex Hospital Open for his first Web.com Tour title, closing with a 5-under 66 for a four-stroke victory.

The 33-year-old former Pepperdine player finished at 16-under 268 at TPC Wakefield Plantation and earned $112,500 to increase his season total to $139,061.

Smith bogeyed the par-4 18th after birdieing Nos. 11, 12, 14 and 15 and parring Nos. 16-17. He shot a 63 on Saturday for a share of the third-round lead with Hunter Haas and Harold Varner III.

Varner finished with a 70 to tie for second with Australia’s Scott Gardner at 12 under. Gardner shot 69.
