One of the characteristics of the AO that has been noted for years: the heat of the Australian summer. To me, fitness is required and rewarded...as well it should be. Years before, the men's final was played during the day. Why is the final now played under the lights? It takes fitness out of the equation...and, for a slam, this should not be the case. Any opinions on this matter? Or information on why the AO tourney officials have done this?
