MELBOURNE (Reuters) - Following Rafa Nadal's problems with cramps in the second round of the Australian Open on Wednesday, Andy Murray has taken a swipe at critics who gave him a hard time after his own struggles at the U.S. Open.

Third seed Nadal fought through cramps all over his body on a balmy night at Rod Laver Arena to beat American qualifier Tim Smyczek in five sets and was praised for his fighting spirit in mainstream and social media.
