To be considered one of the greats, you should definitely have won the WPC and the US Open. Those are the two big ones.
That is why Earl is so great. How many WPC and US Opens has he won? Haters can say whatever they want, the record is clear.
I would agree with others. Bustamante is the strongest, most successful player to not have won.
He still plays great. You never know. He can still win either or both.
Wikipedia lists the following as Bustamante's wins:
