Ewen Murray, a commentator for Britain's Sky Sports, said on air after seeing Woods spit on the second tee during the second round that it was "one of the ugliest things you will ever see on a golf course."
"The Euro Tour is right -- it was inconsiderate to spit like that and I know better," Woods said on Twitter. "Just wasn't thinking and want to say I'm sorry."
Ridiculous, IME. If Ewen Murray is so disgusted by it then he better steer clear of any hockey, baseball, football or soccer games.
