Australian Peter Lonard won the Australasian Tour Championship by one stroke on Sunday from fellow Australian Nathan Green, 25, who finished second again after Lonard made a 10-ft putt for birdie on the 18th.

Lonard set up his win by chipping in for an eagle on the par five 17th and then birdied the 18th for his one shot victory over Green who could only par the last hole.

Green was runner-up by one stroke to Scotland's Colin Montgomerie in the Australian Masters in Melbourne a week ago missed putts on the last two holes to finish on 14-under 270.

Lonard, with a closing five-under par 66, picked up three shots on the final two holes to be one ahead of his fellow overnight leader.

"I really needed to make eagle (on the 17th) and when we were walking to the ball my caddy said: 'That's the perfect place to chip it in from,'" said Lonard.

"It was sitting pretty good on the upslope, in my wildest dreams I didn't think I was going to hole it and then go birdie up the last."

Lonard's win in the $780,000 Championship elevated him to second on the Australasian Order of Merit.

This earned him a place in the British Open field alongside Merit winner Aaron Baddeley and New Zealander Michael Campbell, who was third on the Order of Merit.

Lonard will contest the European Tour's Dubai Desert Classic followed by the Qatar Masters in the next two weeks.

19-year-old Aaron Baddeley whilst finishing down the leader board won the Australasian Order of Merit title in his rookie professional year.

Baddeley successfully defended his Australian Open title this season and also won the Greg Norman International in Sydney, beating Spaniard Sergio Garcia in a playoff earlier this month.

"It's a bit disappointing how I played the last couple of days but in the end it's my first season as a professional," Baddeley said.

"I didn't play all the events and to win the Order of Merit is awesome."

"I'm very proud of myself. I'm really looking forward to getting over there to America. I know my game is really close to being really good."
