Jordan Spieth is already firm favourite to capture the PGA Championship next month and complete the golfing Grand Slam.

Spieth sealed The Open title at Royal Birkdale on Sunday, adding to his US Open and Masters triumphs, meaning he only need the PGA to land all four majors.

The 23-year-old now has the chance to become a golfing legend next month, and become only the sixth golfer of all time to achieve the Grand Slam following on from Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods.

The PGA takes place at Quail Hollow next month, and Bookmakers are already making him favourite to win.

bet365 also list him at 20/1 to become the most decorated player of all time by taking over from Nicklaus’s record of 18 majors.

bet365’s Steve Freeth said: “A trap to line victory for a big priced favourite – you can guess the outcome!”
