Murray hits form in Melbourne after operation transformation

Andy Murray believes he is already reaping the rewards of his back surgery.

The Scot went under the knife in September after experiencing problems on and off for 18 months, particularly on clay. Murray played his first grand slam match since the operation against Go Soeda in the opening round of the Australian Open on Tuesday and was very impressive.

The 26-year-old was on court for less than 90 minutes in his 6-1 6-1 6-3 victory and struck 32 winners.
