No other major has the same tendency to surprise as much as the USPGA. John Daly was a "nobody" when he won in 1991 with his grip-it-'nrip-it philosophy while Wayne Grady was the previous year's winner and the likes of Larry Nelson and Hubert Green had their names etched on the trophy in the 1980s.

Since then, Nick Price has twice captured the title - in 1992 and again in 1994 - and, even if Mark Brooks (champion in 1996) hasn't quite lived up to the reputation of a major winner, Davis Love's win last year confirmed the impression that the season's last major is nurturing quality winners.

This week's championship on the tight Sahalee course indicates that quality will be very much the by-word. Although Price showed a return to his best when winning the St Jude Classic last week and is a tempting 16 to 1, it is hard to look beyond David Duval, who is a keenly-priced second-favourite at 14 to 1, all of six points behind Tiger Woods.

Duval is a class act and should give supporters a good run for their money. An each-way saver on Vijay Singh at odds of 33 to 1 could be fruitful.
