For the second straight year, the British Amateur champion has defeated the US Amateur champion at the Georgia Cup.
Spectators at The Golf Club Of Georgia, north of Atlanta, were treated to an instant classic between Australia's US Amateur winner Curtis Luck and England's British Amateur winner Scott Gregory.
Neither player ever surpassed a 1-up lead, but it was finally Gregory who won the match on the 19th hole.
The West Australian won the opening hole, but after Gregory claimed the next, the see-saw match was on.
With the match all square, Gregory won the 17th hole with a par, only to bogey the 18th and watch Luck even the match.
Playing the 18th again as the first extra hole, Luck found the greenside bunker and was unable to get up and down, leaving New South Wales Amateur champion Gregory to win with a par.
The British Amateur champions now hold an 11-9 all-time lead in the 20-year history of the Georgia Cup.
Both players will now make their way up to Magnolia Lane and next week's Masters.
