MELBOURNE (AFP) - Australian veteran Peter Senior upstaged his younger rivals to win a third Australian Masters on Sunday, 20 years after donning his last gold jacket at Huntingdale in Melbourne.
Senior fired a final round three-under-par 68 to finish eight-under and beat American amateur Bryson DeChambeau and compatriots John Senden and Andrew Evans by two shots.
Former US Masters champion and two-time Australian Masters winner Adam Scott was fifth at four under par after a final round of 69.
At 56, Senior became the oldest player to win the title, eclipsing 50-year-old American Gene Littler's victory in 1980.
Senior also won the tournament at Huntingdale in 1991 and 1995.
It was the veteran's 34th professional win and follows his triumph at the Australian Open in 2012.
"You don't expect to win these events any more," Senior said.
"I'm over the moon to win this tournament. The (Australian) Open a few years ago (2012) and the PGA before that (in 2010), all over 50 years, that's a big thing for me."
Senior started the day with a share of third place and held a three-shot lead with three holes to play before bogeying the 17th.
Evans also dropped a shot on the tricky par-five 17th to end a two-hole birdie run and then also bogeyed the last to deliver the title to Senior.
World No. 12 Scott, who led after the first two rounds, endured an up-and-down final day.
The 35-year-old picked up five birdies but had a costly double-bogey on the par-five seventh and another bogey on the par-three 15th to sign for a 69.
The former world No. 1 faced an uphill task after he blew out with a 77 in Saturday's third round.
