I think sergio is a frustrated man.
He cant win even though he knows he has the talent.
He cant figure out what he needs to do to win = frustrated.
I was watching the tour cast on the internet of live feeds from the masters last year. I watched Tiger Woods hack up a loogie and spit it right on on the green..........at Augusta !!! Still not the same as spitting in the cup.........that was just stupid. If he is not embarassed about that he is an arse.
