The seeding system for events has also been revised, with only one in four players now favoured instead of one in two.

"There are various reasons for this," explained said PSA chief executive officer Alex Gough (pictured).

"It was felt that we over-protect players using the current system – and this often led to too many one-sided matches in the first round or two.

"The new system will create more opportunity for lower-ranked players to play similar ranked players in the first round - therefore creating more opportunity for all players, which in turn leads to more motivation, leading to an improved standard of squash over time.

"We have a strong enough series of events now to balance out tougher draws that players may have over a 12-month period.

"We fully believe that these new changes will enhance the work already done."

Heading the PSA World Tour from 2011 will be the PSA World Open, the premier event with a minimum prize-fund of £177,653 ($275,000).

This stand-alone event will receive extended live TV coverage and will be broadcast on Squash TV.

The winner will be crowned the PSA World Open Champion.

Complementing the PSA World Open will be the new PSA World Series.

These championships will be instantly recognisable as the pinnacle of the sport and will be the main focus of the PSA's global TV coverage and are all broadcast on Squash TV.

These events, formerly known as the Super Series, will produce eight players who will compete in the PSA World Series Finals – the winner of which will be crowned the PSA World Series Champion.

The next level of events will be PSA International 25, 35, 50, and 70.

These range from the larger club and entry-point glass court events all the way through to higher-profile glass court events.

PSA Challenger 5, 10, and 15 events will form the backbone of the Tour and are the entry point for young or up-and-coming professionals progressing through to a more international level of competition.
