In golf what do the Americans call an albatross

Double Eagle
Albatross means three shots under par (−3) (the albatross being one of the largest birds); also called a double eagle in the U.S.

This is an extremely rare score, and occurs most commonly on par-fives with a strong drive and a holed approach shot. Holes-in-one on par-four holes (generally short ones) are also albatrosses.

The first famous albatross was made by Gene Sarazen in 1935 on the 15th hole at Augusta National Golf Club during the final round of the Masters Tournament.

It vaulted him into a tie for first place and forced a playoff, which he won the next day.

The sportswriters of the day termed it "the shot heard 'round the world." Albatrosses are much rarer than par-3 holes-in-one; the odds are estimated at one in 1,000,000: the odds of a hole-in-one are around one in 3,700 to one in 12,500, depending on the hole and on skill.
