Andy Murray insists he still has plenty left in the tank after seeing off Portugal’s Joao Sousa in straight sets to take up his place in the last 16 of the Australian Open.
British number one Murray, who is seeded sixth Down Under, hit 39 winners en route to a 6-1 6-1 7-5 victory.
It was the 27-year-old’s third consecutive straight-sets victory, despite letting Sousa back into the third set from a break down.
Next up for Murray is a clash with Grigor Dimitrov and a chance to make amends for last summer’s Wimbledon quarter-final defeat.
And the Scot admits he is feeling in good shape as he prepare to take on the Buigarian tenth seed.
"I was up two sets and 4-1 and Joao came back into it," said Murray. "He competed very well. He always does.
"I think that was my longest match but I feel pretty good.
"Normally towards the latter stages of this event, you tend to play more matches in the evenings, but so far I played three matches pretty much in the heat of the day.
"Thankfully they've not been too long and it hasn't taken too much out of me."
