Five top-ten finishes in ten major appearances. That proves something, doesn't it? While she must win before she can truly be declared great, she is clearly one of the elites.
I repeat what I said earlier in the thread ... she has the skill set to be a dominant female golfer; the problem is that some people are trying to sell her as something more, as evidenced by pushing her into PGA events now, and IMHO that does her a disservice.
