The British Open

I don't think it has ever officially been the British Open.  I have always called it that and it is often referred to as the British Open here in the U.S.

But I'm a stubborn American and our way is the right way.....    Soccer anyone.  LOL

I definitely think that it comes across as presumptuous to call it THE Open Championship. It seem like a slight against the US Open, which to me is just as prestigious an event--maybe even more so.

Overall it was entertaining and I'm happy for Rory. He struggled for a while after his immediate success, so it's nice to see him back on top. I hate to see the David Duval scenario--when someone on the top of the golf world falls off and never recovers.

Let's take into account that "The Open" is actually the oldest major championship and therefore, was the first. The U.S. Open came along later and U.S. was added for differentiation. Even the official "The Open" often refers to itself as The British Open so IMO it's more a case of historical circumstances and tradition than anything else. 

Rory couldn't be another Duval, unless he were to absolutely wreck his back and never fully recover. It's not like Duval just suddenly got bad
