Australian squash star David Palmer has reclaimed the world No.1 ranking more than four years after last topping the list.

The sensational return to form by the 29-year-old from Lithgow in NSW sees him takes over the top spot from Jonathon Power following his victory over the Canadian in the Windy City Open - the richest squash event in the United States - in Chicago last month.

Palmer, who spent four months as world No.1 from September to December 2001, has enjoyed a highly successful past 12 months, reaching five Professional Squash Association Tour finals - including the World Open - and claiming the Kuwait Open title in March.

Last month he was runner up to fellow New South Welshman Anthony Ricketts in the Australian Open at the Commonwealth Games Squash venue, the Melbourne Sports & Aquatic Centre.

Palmer's next major assault will be the Champion of Champions, held in New York's Grand Central Station on the All-Glass Pro Court this month.

Palmer will face stiff opposition from Ricketts, who will be aiming for his second Tournament of Champions title.

Both Australians will be gunning for gold at next month's Commonwealth Games.
