England have vowed to continue their pack mentality as their hungry pace attack smell blood just one day into the Ashes series.

Relentlessness was the theme for the visiting pace stars on Friday as they rotated with aplomb to reduce Australia to a paltry 9-123 by the end of day one of the first Test, a blistering retort after they’d been bowled out for 172.

Jofra Archer (2-11 off nine overs) started the rout when his low rocket knocked debutant opener Jake Weatherald off his feet and resulted in an LBW.

Mark Wood, who hadn’t played a Test in 15 months, reached speeds in excess of 150kmh and was only needed for five overs due to the effectiveness of the rest of England’s pace attack.

Wood (0-18) didn’t claim a wicket, but his explosive pace put Australia’s batters on edge, with one of his deliveries rocketing up and striking Cameron Green flush on the helmet.

A stumbling Green almost stood on his own stumps, such was the impact of the hit as a bustling crowd of 51,531 watched on.

Brydon Carse (2-45) and Gus Atkinson (0-19 off nine overs) also looked dangerous.

It meant by the time allrounder Ben Stokes came into the attack in the 28th over, Australia were already ripe for the picking.

Stokes made the most of the good work by his fellow speedsters to finish the opening day with 5-23 from six magical overs.

Carse even described Stokes as being in “beast mode”, and he praised the rest of the pace attack.

“I thought we were quite relentless as a group of seamers and Ben rotated us well,” Carse said.

“It’s just a collective messaging throughout the group, and everyone’s 100 per cent buying into that, and we’re never going to shy away from that.

“Hopefully that relentlessness, and passing the ball over to one another, and sticking to what we want to work towards as a group of seamers will pay us in good stead.”

Wood and Archer aren’t slated to make it through all five Tests, with the injury-prone duo to be rotated in a yet-to-be-determined manner.

But with the likes of Josh Tongue and Matthew Potts waiting in the wings, England have a bristling pace attack that has taken on a pack mentality.

“The group of six or seven fast bowlers that we have, we all offer different skills and attributes,” Carse said.

“Hopefully leading into Saturday and throughout the rest of the series, we can complement each other well.

“I think we bounce off each other, we all have slightly different attributes. And keeping it relatively simple, I think that’s stood us in good state today.”

‘Long way to go’: Starc

Star quick Mitchell Starc has refused to buy into suggestions that Australia panicked during a dramatic collapse late on a remarkable opening day of the Ashes at Perth Stadium.

Several Australia batters – including Starc, Travis Head and Alex Carey – played poor shots to be dismissed.

Starc attempted to praise the bowlers from both sides for the carnage, rather than blame the pitch, or the poor choices of the batsmen.

“It’s two innings of cricket,” he said.

“There’s a long time left in this series, and this game.

“No doubt the brains trust will have a chat, and we’ll come here for day two with the same approach of being pretty calm and pretty level.”

The parallels to last year’s Perth Test, where 17 wickets fell on the first day, are impossible to ignore.

India made just 150 batting first, but then reduced Australia to 7-67 at stumps on day one before going on to win the match comfortably.

Australia were still able to recover and win three of the next four Tests to reclaim the Border-Gavaskar Trophy 3-1.

Helping Starc and the rest of the Australia bowling group is that they only bowled 33 overs at England on day one so they should be relatively fresh heading into a quick second-innings turnaround.

“Sometimes you’re faced with that,” Starc said.

“I’ve played long enough to have trained the body to need to do that if I have to.

“You always like to sit back and watch your team bat.

“There’ll be other days where we’re in the field for a long time.”

But Starc, who grabbed his seven-wicket haul off 12.5 overs, will have to carry more of the load than normal, with captain Pat Cummins and fellow star quick Josh Hazlewood sidelined due to injury.

Scott Boland (0-62 from 10 overs), who blitzed England on Test debut at the MCG four years ago, was treated with disdain by the visiting batters on Friday.

Without Cummins and Hazlewood, England promised to target Boland, as they did in the 2023 Ashes, and they were true to their word.

Debutant Brendan Doggett made an impressive start, taking the key wicket of Harry Brook to finish with figures of 2-27.

“He certainly bowled a better first over in Test cricket than I did back in the day,” Starc said of Doggett.

“Thrilled for him to get his baggy green and take a few wickets.”

Doggett will bat with Nathan Lyon on Saturday as the tail-end pair attempt to secure crucial runs to reduce England’s lead of 49.
