I saw that Jimmy called it the Austrian in his Twitter post. It's not a big deal and you can't edit and correct your mistakes in tweets. You either delete it and start over or run with it. Most people know it's a typo or didn't notice it. Jimbo wasn't famous for his writing skills or his manners in speaking, but he speaks from the heart.
All that said, it's a good thing this isn't the Austrian Open because they're at least a nutty as the Australian government at this point.
