Whether you want to call it a choke or not, Phil just didn't play as good as the other guy.
In hockey, a team has a 2 goal lead going into the third period, and they lose, they choked.
Where do you draw the line on what a choke is in golf? 1 shot? 2? 4?
Point can be made either way, I guess. *Technically*? He choked. Whether it was that egregious or not, I don't really know.
