DAY 3: Australia's Head slams unbeaten 142 to crush England's Ashes hopes

Danger man Travis Head crunched his fourth century in as many tests at Adelaide Oval Friday as Australia built a 356-run lead over England to stand on the brink of retaining the Ashes.

The hosts were 271-4 at stumps on day three of the third test with Head on 142 and first-innings century-maker Alex Carey not out 52, taking the five-match series out of England's reach.

England must win after crashing inside two days at the first test in Perth and inside four in Brisbane, both by eight wickets.

But it appears to be an impossible task with the highest run chase at the ground 316 by Australia against England in 1902.

Head said the job was not finished yet and Australia had to "rock up again" on Saturday.

"We've had another really, really good day today.

"Tomorrow will be another huge day, the wicket is deteriorating and starting to spin.

"The goal is to try and put on as many as we can in the morning and get to work and try to win the test match."

Head's crucial ton, his 11th, came off a composed 146 balls although he almost didn't get there, dropped on 99 by Harry Brook as impatience got the better of him.

He has now scored a century in four consecutive tests on his home ground, following 140 against India last year and 119 and 175 against the West Indies

'IT CALLS FOR HEROES'

"The way Head has batted is next level, and he has shown us how to go about it," conceded England spin coach Jeetan Patel.

"Every game of test cricket we play, especially out here in Australia, calls for heroes.

"And we haven't had them just yet, but maybe we will have them tomorrow and the day after."

Australia suffered an early setback in a tense 20 minutes before lunch after England were all out for 286 on the back of Ben Stokes's gritty 83 in response to Australia's first innings 371.

Bryson Carse trapped Jake Weatherald lbw for one and he did not review although replays showed the ball was pitching outside leg stump.

It gave England a glimmer of hope, but after the break Head slammed the door shut, cutting and chopping boundaries all around the ground.

Marnus Labuschagne went for 13 when he edged Josh Tongue to Harry Brook at slip, with reviews showing it carried.

Usman Khawaja, who hit a defiant 82 in the first innings after his last-minute call-up for the ill Steve Smith, was a perfect foil for the more aggressive Head.

But on 40 he was caught behind off Will Jacks and Cameron Green followed soon after for seven, edging Tongue to Brook.

After getting through the nervous 90s, Head finally brought up his century with a four off Joe Root, taking off his helmet and kissing the turf before pumping his fists.

While not in the same vein as his match-winning 69-ball century in Perth, it was a critical knock, supported by Carey and aided by Stokes not bowling.

GUTSY STOKES

Patel said Stokes, who batted for two sessions on Thursday in 40 Celsius heat, was not injured.

"From what I understand he is fit to bowl," said Patel.

"He's just knackered, he's taken a lot out of himself to get to this point in the game."

On Friday's resumption, Stokes and Jofra Archer kept England's dreams just about alive with a stirring 106-run ninth-wicket stand.

They began at 213-8 in muggy conditions with Stokes not out 45 and Archer on 30.

Stokes, who suffered leg cramps and dehydration during his gutsy rearguard action on Thursday, brought up his slowest ever 50 in tests, off 159 balls.

He finally fell when Mitchell Starc took the new ball and bowled him, with Stokes one of the few players who showed the fight he had demanded before the game.

Archer was another, ably helping his captain.

The fast bowler was the last man out when caught by Labuschagne off Scott Boland for 51 -- his highest test score and a maiden half-century

Boland ended with 3-45 while Pat Cummins took 3-69 in his first test since July.
