Tiger Woods has birdied three of the last four holes to win the Memorial Tournament by two shots in Ohio as Australian Aaron Baddeley finished tied for ninth.
As overnight leader Spencer Levin dropped four shots on the back nine during Sunday's final round, Woods pulled off a brilliant finish, holing birdies on the 15th, 16th and 18th holes to claim victory.
Woods shot a five-under 67 to finish nine under for the tournament, with Argentine Andres Romero and South African Rory Sabbatini tied for second two shots back.
The victory saw Woods equal Jack Nicklaus' tally of 73 wins on the PGA Tour, with the pair tied for second behind Sam Snead (82 wins).
American Levin finished in a tie for third with countryman Daniel Summerhays on five under, while Matt Every and Jonathan Byrd were a further shot back.
Baddeley carded an even-par 72 to finish at two under and tied for ninth with Englishman Greg Owen and Japan's Ryo Ishikawa.
Nick O'Hern and Greg Chalmers (both four over) and Adam Scott and Rod Pampling (both five over) never got going on the weekend.
Of the other Australians to make the cut, Robert Allenby (eight over) and Geoff Ogilvy and Marc Leishman (both nine over) struggled.
Woods birdied five of the first seven holes on Sunday, including three straight starting on the fifth, to keep himself in the hunt for the title at the Muirfield Village Golf Club.
Bogeys on the eighth and 10th holes seemingly put victory out of reach for the American.
But from there, the 36-year-old former world number one consolidated with four straight pars before a birdie on the par-five 15th sparked a brilliant late run.
Woods' 48-foot chip from the rough on the par-three 16th for another birdie - a shot described by Nicklaus as the greatest he's ever seen - brought the crowd to their feet, while another birdie on the final hole completed a memorable win.
On the Nationwide Tour, meanwhile, James Hahn won a play-off against Scott Parel to clinch the Rex Hospital Open at the TPC Wakefield Plantation.
The 30-year-old shot a four-under 67 to finish top of the leaderboard alongside Parel on 13 under for the tournament.
Hahn birdied the 18th on the second time of asking in his play-off against Parel to claim his first victory on the Nationwide Tour.
Starting five shots off the lead at the beginning of Sunday's final round, Hahn shot five birdies, including three on the first five holes, to reach the top of the leaderboard.
Jin Park, B.J. Staten and Jim Renner finished tied for second on 12 under.
Steven Bowditch was the best-placed Australian at nine under and tied for 10th, while Scott Gardiner was a further two shots back.
Cameron Percy (eight under) was a strong performer, while Aron Price (two over) was the only other Australian to make the cut.
