OKALAHOMA State University student Sam Lee is a top contender for a spot in the Fiji golf team for the world cup in Japan next September.
Lee climbed 246 places in the latest world amateur rankings to 796 position.
This makes him Fiji's best ranked amateur golfer in the world.
He moves ahead of Olaf Allen Jr who dropped down to 1672.
Lee was Fiji's best performer at the Asia Amateur Teams Championship in Thailand last month.
He finished with seven over par 295 and was tied for 41st place in the individual category.
Lee has pledged to remain in the amateur division in a bid to boost Fiji's medal winning chances in the 2015 Pacific Games in Papua New Guinea.
National Golf Association of Fiji secretary Amitesh Chandra said Lee would be returning to defend the amateur title in the Fiji Open Championship next year.
Amitesh said the former Rampur College student was a strong contender for the world cup squad.
"Lee is playing for the university team," he said.
"We will monitor his scores next year. He has shown his commitment."
The Srixon Cleveland Champion of Champions at the Pacific Harbour Golf Club next month will serve as the first trials for the world cup.
World Ranking's: Sam Lee (796), Olaf Allen Jr (1672), Anuresh Chandra (2510), Roneel Prakash (3569), Baarroon Hussain (4637), Amitesh Chandra (4785).
