I would say so, yes. He needs to win a British Open to be considered a true great IMO though.
Encouraging week for Tiger, the fact he can play so badly and hit so many shit shots and still be right in contention is a good sign. Although it worries me that he's continually getting close but not quite winning in the last few years - needs to cut out the silly bogeys, he's become really prone to them early in final rounds and then by the time he makes a charge (like he did again yesterday) it's too late.
Westwood was pretty classy in defeat
he might not get a better chance though.
