MELBOURNE, Australia — Popular usage to the contrary, the definition of insanity is not actually doing the same thing over and over again and expecting a different result.
Perfectly sane tennis players on losing streaks do it all the time, and so Andy Murray — of sound mind, if not always even temper — will do the same thing over again in Melbourne on Sunday. He will walk into Rod Laver Arena looking a little disheveled and expecting to find a way to beat Novak Djokovic in an Australian Open final.
Murray has lost all four of his past matches against Djokovic here, including three finals.
