It isn't just Americans

I'm listening to Australian Open Radio, and the announcer just butchered the names of Jelena Jankovic, Anna-Lena Groenefeld and Daniela Hantuchova. He got Svetlana Kuznetsova's name right, though, making him probably the only commentator to do so. I am continually perplexed that people who are paid very good money to speak cannot pronounce the most important words they are paid to say. Not to mention the fact that they are supposed to be "experts" on tennis. I just wish the players would be more assertive about the pronunciation of their names, but perhaps they are afraid to correct the announcers.
