Caddies may have dual roles at the Olympics. Their services may be needed not only for club selection but also as game wardens.
The caddy/game warden would be responsible for scaring away the menagerie of animals that are said to hang around Holes 2, 3 4,5,and 9 of the Olympic golf course. Three-toed sloths should not pose a problem, even for slow players, but the boa constrictors, monkeys, and caimans and capivara (capybara) could run off with or swallow the golf balls.
The USGA rules of golf regarding animals and balls says that if it is certain that a player’s ball is at rest and has been moved by an outside agency, no penalty is incurred and either the original ball or a new ball must be replaced at the spot that the ball was moved from (Rule 18-1).
There is a complication here, however, if an animal moved the ball it is highly unlikely that the player will know the exact spot, especially if this is viewed from a distance. So here, the golfer must drop the ball nearest to the estimated place where it lay (Rule 20-3c), except on a putting green where the ball must be placed as near as possible to where it lay.
A minor complication is when the ball was still in motion when deflected or moved by an outside agency, in other words, if you hit an animal. This may prove the biggest problem! This comes under the”rub of the green” rule and there is no penalty and the ball must be replaced as it lies. However, if an animal picks up the ball and runs off with it the player should drop a ball without penalty at the nearest spot.
It would probably be wise for the caddy to be well versed in the minutiae of the rules of golf before heading on to the course. So, no guns needed, just the Rules!
