The 2002 champion will collect $1 million, nearly double the prize Mark O'Meara earned for winning the 1998 event at Royal Birkdale. Last year's winner David Duval took home $858,300 from a purse worth just over $4.7 million.
The increase will also affect the last man on the leaderboard after 72 holes (the 70th-place player will receive $11,900) as well as the golfer bringing up the rear when the 36-hole cut is made (No. 156 is now worth $2,900).
'We recognize the cost of competing in the championship for overseas players, and have therefore put measures in place which will offset those costs, and maintain the international strength of the field,' said R&A championship secretary David Hill.
The 131st British Open will be played July 18-21 at Muirfield in Scotland.
