Those words showed maturity but also the teenager’s high standards.

Corteen-Coleman perched herself next to England’s coaches on the balcony for much of her side’s chase. She believed her work for the day was done, but her most consequential moment was still to come.

Ten runs were still needed when she emerged as the last batter to join Dean.

Crucially, she helped Dean run twos and, with solid defence, bettered her previous high score of one not out in The Hundred to finish unbeaten on three and sealed the win.

“I am glad I looked calm because I definitely wasn’t,” she said.

“The main point for me was to keep it really simple.”

Corteen-Coleman did not, of course, complete the win alone.

Central was the role of Dean, who admitted to exposing her team-mate more than she intended by taking singles early in the over, but otherwise played the situation well.

Much has been made of Dean’s ability to hold her mettle in chases. There has been some success but failure too – notably in the Mankad ODI at Lord’s in 2022 and the second ODI of the Women’s Ashes last year.

This time, standing in as England captain for the first time, Dean dragged her side over the line.

If England’s training camp with the army last week was supposed to develop leaders, this was Dean’s Passing-Out Parade.

“I have worked on having that calmness and being ready in any situation but that mainly came from Deano,” added Corteen-Coleman.

“If I came out and she was panicking I would have been under the pump.”

Corteen-Coleman emerged with the words of coach Charlotte Edwards in her ears. She told her to back her strengths and keep a clear mind.

That was backed up by Dean in the middle.

“She came out with good clarity,” said Dean.

“I said, ‘Yorkers have been successful for them so they will probably look to get under your bat’.

“We decided getting forward was the best option.

“Tilly is really proactive with her thinking. She has a good cricket brain.”
