What does a caddy do?

I've just heard that a caddy can earn up to 10% of a golfers winnings and that Tiger Woods has sacked his.

I have no idea on golf, so before I send Tiger my CV, what exactly does a caddy do? I always thought they just held the bags and the umbrellas?

Wouldn't mind 10% of some of the money Tiger used to earn!

Caddying is a real art form.
They show up at a tournament a few days early and map out the entire course while taking into consideration "their golfers" game. They organise everything to do with the golfers equipment, including maintainance, new clubs and even down to making sure they have enough balls and the correct types of tee's.
On playing days, they advise the golfer of yardage, potential hazards and club/shot selection. They also do a bit of amateur pyschology and generally manage the players mood as best they can.

Its only the top 5-10% of caddies that lead a celebrity lifestyle. The rest struggle to make ends meet more often than not.

This book is worth a read, totally hilarious and tells a true caddie's story.

I always remember Ian Woosnam's caddy telling him, during a round, that he had put too many clubs in the bag and he was going to have to face a two stroke penalty. Ian went ballistic.

A few years ago but think it was final round of US Open or Masters and Ian was in the mix to win.

Hilarious and cringeworthy at same time.

He was no Bagger Vance thats for sure

:confused: looks after your balls?
