Luke Donald has overtaken Rory McIlroy to become world number one again after winning the Transitions Championship.
The Englishman needed a win in Florida to reclaim top spot from Ryder Cup team-mate Rory McIlroy - and he did just that by holding his nerve to win a four-man play-off.
Robert Garrigus, Jim Furyk and Sang-Moon Bae were the players edged out by Donald after the quartet had finished the fourth round on 13 under par.
Rory McIlroy must have been keeping an eye on proceedings at Innisbrook as he was quick to congratulate Donald via his Twitter account. McIlroy tweeted: "Well I enjoyed it while it lasted! Congrats @LukeDonald! Impressive performance!."
Padraig Harrington hit a course record 61 on Thursday but eventually had to settle for a share of 20th place, finishing the tournament on seven under
A run of five birdies in the first 11 holes moved Donald into contention, before he consolidated with seven successive pars to make sure of a 16th top-10 finish in his last 22 events.
He hit an excellent approach shot on the first hole of the play-off with a seven iron from the rough - and holed the putt to make sure of the victory.
Robert Garrigus had also given himself a birdie opening - but the American's chance had gone when the putt went past the hole.
Donald's victory made it three European victories in a row in America after McIlroy triumphed at the Honda Classic and Justin Rose did likewise at the Cadillac Championship.
Donald admitted the win was a morale booster ahead of the Masters.
He said: "I feel like I've achieved a lot in my career but this is perfect preparation. I've got two weeks off now and can look forward to Augusta.
"I certainly was a lot more nervous about getting to number one the first time. This time it wasn't my focus - I was focused on winning the tournament and it all worked out."
Garrigus had given himself a chance of victory with birdies on the last two holes giving him a 13-under round of 64.
Bae, seeking to become only the third South Korean to win a PGA tour event, held the lead yesterday but a final-round 68 was enough to earn him a place in the play-off, while joint overnight leader Furyk managed a 69.
Fellow overnight leader Retief Goosen slipped out of contention, finishing on seven under after a final round 75.
Goosen, twice a winner of the event, made a poor start to his final round, with a double bogey on the first. He dropped another shot at the next hole and failed to recover.
Ernie Els appeared to be in a good position when he held a narrow advantage with two holes to play but a pair of bogeys on the final two holes ended his hopes of victory and saw him finish a shot off the pace alongside Scott Piercy, Jeff Overton and Ken Duke.
Piercy hit the round of the day, a nine-under-par 62 to claim a share of the lead. The 33-year-old birdied seven birdies in his first nine holes today and added two more at the 14th and 16th.
In contrast, Charlie Wi endured another testing day as the South Korean made an octuple-bogey for the second successive week on the PGA Tour, carding a 13 on the par-five fifth hole.
