Adam Scott cemented his just-obtained world No.1 golf ranking, winning the $US6.4 million ($A6.92 million) US PGA Colonial tournament on the third hole of a playoff Monday.
Scott came from 11th after the third round to tie for the lead with US player Jason Dufner.
Both players pared the first playoff hole and birdied the second, before Scott nailed another birdie to seal the deal.
It was Scott’s first PGA win for 2014 and came just a week after he grabbed the World No.1 spot.
Fellow Aussie John Senden finished two shots shy of the leaders in fifth.
Scott’s win makes him the first golfer in PGA history to win the Texas Grand Slam.
Thirteen players fell one tournament short of the slam, among them Ben Hogan, Sam Snead, Byron Nelson, Arnold Palmer, Gene Littler, Nick Price, Ben Crenshaw and Phil Mickelson.
Scott won the 2007 Shell Houston Open, 2008 HP Byron Nelson Championship and 2010 Valero Texas Open.
On the European Tour, Rory McIlroy admitted he had mixed emotions after completing a roller-coaster week by coming from seven shots back to win the European PGA Championship at Wentworth.
The Northern Irishman – who announced his split from tennis star Caroline Wozniacki on the eve of the tournament – fired a sparkling six-under-par 66, for an aggregate of 274, 14 under par, to win by a shot from Ireland’s Shane Lowry.
Denmark’s Thomas Bjorn surrendered a five-shot lead by the time he had got to the seventh tee after a disastrous seven on the sixth but still had a faint chance of victory after birdies at the 16th and 17th.
Bjorn, aiming for his 16th European Tour win, finished with a 75 and had to settle for a share of third place with England’s Luke Donald with both finishing on 276, 12-under.
“It been a weird week. When I got inside the ropes it was a little bit of release – it gives you four or five hours of serenity,” McIlroy said on Sunday.
“I can’t explain it – it has been a week of very mixed emotions but I am sitting here looking at this trophy thinking ‘how the hell did it happen?’”
McIlroy got his round going with an eagle three at the fourth but was knocked back by bogeys at the sixth and ninth before streaking home in 32.
He chipped in at the 10th for a two to go to 10-under and took the lead with a birdie at the 12th before successive birdie fours at the par-5 17th and 18th holes.
On the 18th he hit his second into a greenside bunker but chipped out to five feet and punched the air when he holed the putt.
