Bethell's century, which took the tourists to 302-8 and a lead of 119, makes the 22-year-old the seventh youngest man to score a Test hundred for England against Australia.

Having come in during the first over, he strolled to the nineties but 29 balls passed with Bethell a hit away from a century.

Harry Brook, England's vice-captain, wafted and waved at Mitchell Starc bouncers at the other end. Bethell's dad, Graham, took deep breaths in the stands.

It was the man that mattered most who appeared the calmest of all.

Bethell had, of course, been here before.

In November 2024, he reached 96 against New Zealand in his second Test, only to nick behind off Tim Southee.

His response afterwards, that it would have been "flair" to "smack that through the covers" hinted at Bethell's freer side - the one that had him pictured doing the YMCA during England's ill-fated mid-Ashes trip to Noosa.

This hundred showed all of his maturity that is so highly regarded by England - and what persuaded them to make him their youngest captain on last year's white-ball tour of Ireland.

"He played in a way that Test cricket has been played for many generations," said former England captain Michael Vaughan on Test Match Special. "You respect the ball and have good technique.

"It was a technical masterclass. A masterclass in composure and calmness.

"The strokeplay, when he got a chance to score, he didn't try to overhit it. We have seen a batting masterclass from someone who let the ball come.

"He didn't hit the ball in the air that often. It was a throwback."

Though the landmark came with a flick for four over mid-wicket off Beau Webster's spin, Bethell's first ton was moulded in a style from the old school.

While defending the danger area around his stumps, he timed back-foot punches rather than slashing cuts and clipped from his pads to keep the score moving.

A glorious on-drive off Michael Neser was the highlight and a dismissive pull off Cameron Green through mid-wicket a statement.

"I had two shots and a half," said Cook, famed for his cuts, pulls and clips, on TNT Sports.

"Four shots would help anyone be world-class. He has guts and determination.

"There were some really tough balls but he has a nice solid technique down the ground.

"Clip, pull, drive and cut. A classic number three innings."

Bethell said afterwards his ability to bat long, something England have been craving, was formed by being small as a child and his back-foot shots.

"I only became able to hit boundaries and sixes when I was 15 or 16 so I got that ability to bat a long time when I was younger," he said.

He said his back-foot shots came because "growing up in Barbados I got a lot of chin music".

"I was a little bit nervous, but nowhere near as nervous as I was in New Zealand when I forgot to watch the ball and got out," he added.

Cook, the only England batter younger than Bethell to score an Ashes ton this century, said Bethell has "shown the future of England batting after Joe Root".

"In the media box there are a lot of very good Australian cricketers who haven't seen a lot of him and they are purring," he added.

In England, few young careers have been as regularly discussed as Bethell's.

An Under-19 international who moved to the UK from the Caribbean aged 12 for a cricket scholarship, he was plucked for his debut in New Zealand in 2024 despite being a batter without a professional century to his name.

Having broken that duck with a white-ball hundred against South Africa in September, he is now the fifth man to score his first first-class hundred in a Test for England.

"A lot of observers of the game knew he had it in him and you look at him and think that's a Test-match batter but without the experience, the first-class cricket, you never truly know," said former England bowler Steven Finn.

"Today is the day we truly found out Jacob Bethell belongs on this stage."
