Labuschagne puts glut of runs down to 'riding the wave'

Labuschagne's purple patch continued on a slow-scoring deck in Perth, the number three reaching stumps on 110 not out with Australia 248-4 in the day-night encounter.

Don Bradman and Charles Macartney are the only other Australians to have scored three successive hundreds in the longest format.

Labuschagne also became the fourth-fastest Australian to score 1,000 Test runs and the number three says staying in the moment has enabled him to spend so much time in the middle.

"No hundred is easy, but today there was definitely patches where scoring really dried up completely and you just had to be patient and trust you were going to come out the other side," said the 25-year-old.

"It's about riding the wave, not trying to get too high when you are going well, keep everything consistent, keep it process-driven in terms of your mind.

"It's great to get runs, but just making sure you are doing your routines, keeping that clear mind on the field and from there you're just playing the ball as it comes. It's making sure you put a real high price on decision making."

Test debutant Lockie Ferguson went for a scan after suffering a calf injury on a searing hot day and Labuschagne says Australia must try and make the tourists' bowlers suffer in the field if they are a bowler short.

"I think one of the boys said when we came back in that he [Ferguson] pulled up with an injury, but me and [Steve] Smith didn't even know," the centurion said.

"It's a massive advantage they do have an all-rounder [Colin de Grandhomme] in their side, so that probably does lighten the load but it's a massive advantage if we can really bat well tomorrow and keep them out there.
