Djokovic upset in Miami

As I said earlier, I'm a big tennis fan and I just recently heard that Djokovic was upset in Miami in the Sony Ericsson tournament. This guy named Kevin Anderson who is a South African 6-7 beast. He got to the final of the Tennis Channel Open where he lost to Sam Querry. They don't even recognize him as an official pro and he beat the #3 in the world. He came to the US to go to the University of Indiana where he's mistakenly seen as a basketball player. This guy looks really awesome but he's fairly old to be making his first ATP appearance. I'm looking for him to finish in the Top 50 by the end of the year though. that'd be a huge accomplishment for him, and he's shown that he can do it.
