Lowest Putt-Putt miniature golf score in competition

Since the Putt-Putt franchise of minigolf courses was founded in 1954, only four people (all USA) have scored a perfect 18 in competition: Warren Morris in Orlando, Florida, in October 1973; John Napoli in Columbus, Ohio, in May 1979; Rick Baird in Richmond, Virginia, in April 2011; and Greg Newport in Richmond, Virginia, in July 2016. All of these perfect rounds were verified by The Professional Putters Association.

The Putt-Putt franchise was founded in 1954 by Don Clayton in Fayetteville, North Carolina, USA. It was grounded on the principle of "no-frills, all-skills", stripping back the quirky obstacles now typically associated with other minigolf/crazy golf courses such as loops, ramps and moving targets, in favour of shorter, more consistent holes where par 2 is a standard and a hole-in-one is always achievable, more likely through practice and skill than relying on luck. Clayton went on to establish The Professional Putters Association (formerly The Professional Putt-Putt Golfers Association) in 1959, which organizes regional competitions and national contests every year.

Of the four types of course recognized by the World Minigolf Sport Federation (established in 1980) – Béton (raw concrete), Felt, Minigolf Open Standard (MOS) and Eternit (fibre cement) – no 18-shot rounds have been recorded on the first three but more than a thousand players have achieved a perfect round on Eternit courses.
