The sum and substance is that 2 players would go on to the next round of tournaments and he was leading in both. Rather than take both spots he purposefully let another player win one of them - really threw the match - so someone he respected could have a chance.
I'm pretty sure Grant is a good guy to play a round of golf with. I'm pretty sure he would try and beat you to death and when you were groaning and bleeding hit you a few more times if it was 1:1, him against you. That's what competitive golfers do. They are, as in Grant's case, pretty damn fine human beings.
Nice Grant. Very nicely done.
