The idea is that, with all the majors finished by the end of July, there would be more time in the season for the PGA Tour's money spinning FedEx Cup which offers a $10,000,000.00 pay day for the winner of the Tour Championship in September. 

"This is a special day and a great statement about our players and our Tour," said PGA Tour Commissioner Jay Monahan. "Moving the USPGA Championship to May would have the knock-on effect of the TPC at Sawgrass being played in March."

This spells good news for the European Tour too, as it will give the Race To Dubai (which concludes in November) the chance to attract some of the biggest names from the PGA Tour. It is estimated the change in diary for the USPGA will happen in two to three years time.
