Murray feels physically stronger than last year post advancing to Oz Open quarters

Britain number one Andy Murray admitted that he felt much stronger physically than last year in the fourth-round tie against Bulgarian opponent Grigor Dimitrov.

Sixth seeded Murray, who trounced Dimitrov 6-4 6-7 (5-7) 6-3 7-5 in a pulsating thriller, cruised into the quarterfinal round of Australian Open.

Murray, who is eyeing his third major, said that he felt physically better than the last year for a match that went three and a half hours, the BBC reported.

In light of his performance, he further said that his body allowed him to play that way for the whole duration of the match, adding that he didn't feel tired, his back felt good and had not been feeling stiff at all, the report added.

Murray will now face Australian opponent Nick Kyrgios, who saw off Italian Andreas Seppi, to book a semifinal berth.
