A great player and a gentleman off the golf course BUT what about his behaviour on the golf course ?

Swearing, spitting, shouting, chucking clubs about.

It's actually quite embarrassing watching him at times. For instance at the World Series last week, there was this close up of him gozzing (UK slang for spitting). It wasn't very nice. Even the commentators said it was an awfull habit to have.

He needs to watch Phil Mickelson or Ernie Els and learn how to behave on a golf course !
