While most of our country is freezing these days, the tennis fans down under sure aren’t hurting for any fun in the sun. Perhaps a little too much sun. It’s well over 100 degrees at the Australian Open and it takes a toll even on the pros. The key to playing in the heat is constant hydration, energy conservation and preparation. Serena Williams said in one interview that she is fairly well-conditioned to the weather since she regularly plays in hot and humid Florida. Some have passed out from heat exhaustion while others are playing extra aggressively to finish up the game more quickly and avoid the heat. Whatever the case may be, it’s another great major to watch and see who will come out on top this time. My prediction is Djokovic and Williams.
