MASTERS marvel Jordan Spieth is firming as the headline act for the World Cup of Golf at Kingston Heath in   November when an irresistible duel against world No.1 Jason Day looms. 
The American star, who has dominated the Masters like no golfer since the young Tiger Woods, has given indications to the PGA Tour that he is eager to tackle their two-man teams event, according to a source in the US.
Should halfway leader Spieth win back-to-back Masters titles from his strong 66-74 launchpad, it would also improve his chances of finalising the trip.
Spieth has an Olympic medal chase in Rio in   August as a different goal and playing for a World Cup, which is engraved with the names Jack Nicklaus, Arnold Palmer, Tiger Woods, Sam Snead and Ben Hogan as past American winners, would be another.
The extra allure is that Spieth, as the top-ranked American, gets to select his own World Cup partner for the fourball and foursomes format.
Spieth made a private detour to Melbourne last   November to play Kingston Heath before the Australian Open in Sydney and reportedly loved the sandbelt course he chose to walk, hauling his own clubs and enjoying a beer.He would be the biggest drawcard at the famous layout since 2009 when Woods broke his tournament drought by winning the Australian Masters.
