Cricket: Australia seize control over India after shaky start in deciding Brisbane test

Marnus Labuschagne has ridden his luck to a home-ground century, as Australia exploited India's injury woes and punished their poor fielding to reach 274/5 on a steamy opening day of the fourth-test decider in Brisbane.

Captain Tim Paine was 38 not out and all-rounder Cameron Green on 28, with the Aussies holding sway, after winning the toss and batting on a GABBA pitch that flattened out obligingly for the hosts under a blazing sun.

Dropped on 37 and 48 before tea, Labuschagne feasted on India's makeshift attack in a 113-run partnership with Matthew Wade (45), before Australia's No.3 was out slogging for 108.

Without a single first-choice bowler available - all sidelined or long since departed with injuries - India blooded two debutants in paceman T Natarajan and spin-bowling all-rounder Washington Sundar, among four changes to the XI that held on for a courageous draw in Sydney.

Both the new boys had their moments, with Sundar claiming Steve Smith (36) as his first test wicket, when the master batsman chipped a half-volley to short mid-wicket.

Natarajan dismissed Labuschagne and Wade, the latter falling with a typically reckless cross-bat swipe.

But India's cards were dealt earlier in the day, when stand-in skipper Ajinkya Rahane dropped a simple chance in the gully that would have removed Labuschagne for 37.

The second part of a rapid double-blow saw bowler Navdeep Saini off the ground with a groin injury and unable to bowl again.

India would have had Australia at 93/4 at that point and could have mitigated the damage, had Cheteshwar Pujara held a much tougher chance at first slip, when Labuschagne nicked Natarajan behind.

But from there, the tourists could not find another wicket until Australia had reached 200.

Labuschagne attacked with gusto after tea, bringing up his fifth test century with an all-run four and a glorious cover drive.

Soaking up the cheers of fellow Queenslanders in the terraces, Labuschagne ripped off his helmet and kissed its crest.

Paine got off to a watchful start, but ramped up the pressure, after paceman Shardul Thakur put down a waist-high caught-and-bowled chance that would have dismissed Green for 19.

Though gutted by injuries, with pace spearhead Jasprit Bumrah, all-rounder Ravindra Jadeja, batsman Hanuma Vihari and spinner Ravichandran Ashwin all ruled out, India battled hard.

Yet they could not match the heights of a thrilling first hour, when they removed both Australia's openers before drinks.

Paceman Mohammed Siraj, the two-test leader of the attack, had David Warner caught for one with the sixth ball of the morning, with Rohit Sharma diving to his right from second slip to take a brilliant, low catch.

First change seamer Thakur, included for only his second test, struck with his first delivery when recalled opener Marcus Harris (5) flicked straight to square leg.

Though cracks were opening up on an unusual Gabba pitch, Australia will be confident of building on the total at a ground where they have not lost a match since 1988.
