A double-eagle is a rare bird on the golf course - much rarer than a hole-in-one.
To make a double-eagle requires acing a par-4 hole or scoring 2 on a par-5 hole.
The unscientific odds of scoring a double-eagle are about a million-to-one. The unscientific odds of scoring a hole-in-one are about 13,000-to-one.
(Discrepancies in odds will occur due to the disparate skills of professionals in match play....and everyday duffers on their local links.....plus lack of verifiable records....in other words the odds stated are merely educated guesses.).
