Sergio will probably be fined pretty big by PGA and European Tours, and maybe get the bill from NBC. Let's just go with "It is what it is".
More interesting and important was Tiger's reaction to his bad luck on 6th hole after his chip shot. He wanted to slam his club; but he restrained himself and then went about his business. He was in control of his emotions all day on a very difficult day.
Hey, I saw that moment of Tiger's too. I thought to myself, temper temper Woody and it worked he controlled himself and moved onward. lol
