ESPNcricinfo Awards 2022 Women's ODI batting winner: Head over, Heals
Three years on from her stunning display against India at the MCG in a World Cup final, she tore England to shreds with another magnificent display in another.
Four days earlier, it had seemed like her 129 in a mammoth 216-run stand with Rachael Haynes in the semi-final against West Indies couldn't be bettered, but she went on to do just that.
Her innings took time to build. At the end of the ten-over powerplay Australia were 37 for 0 and Healy was 15 off 25 balls. Sophie Ecclestone's first over produced a couple of nervous moments, but then Healy accelerated. Her fifty came in 62 deliveries and the hundred arrived at exactly a run a ball. She followed Ricky Ponting and Mahela Jayawardene in becoming the third player to score two hundreds in the knockout phase of an ODI World Cup.
Then it really got wild. Off her next 38 balls Healy would chalk up another 70 runs with 26 boundaries - curiously there was not a single six in Australia's massive total. Healy's penultimate four took her to 500 runs in the tournament (with 299 coming in her last two innings) and there was anticipation of a double-century before she was finally out, stumped by Amy Jones.
England's fielding was ragged. They had just given Haynes a life on 47, and Healy was also given a reprieve. On 41, she pulled Kate Cross to midwicket where Nat Sciver couldn't hold on. Two overs later Healy launched the same bowler through the leg side to reach 50. And that was just the start.
170 Healy's score is the highest individual score in a World Cup final; in setting the mark she passed Adam Gilchrist's 149 against Sri Lanka in 2007
509 Number of runs Healy made in the tournament. She became the first player to score over 500 runs in a Women's ODI World Cup. The previous record was 456 by Debbie Hockley in 1997, a figure also surpassed by Haynes in this tournament.
2 Healy's 170 was the second highest score in a Women's ODI World Cup for Australia, after Belinda Clark's 229 not out against Denmark in 1997.
What they said
"I don't think I've ever dreamt of anything like that before, I can guarantee you that. But I'm just really proud to have been able to contribute to this win."
- Alyssa Healy
"To do it in a World Cup final, I am probably not surprised, to be fair she's done it before as well. To be able to come out and play so well, to play those shots she was playing was ridiculous."
- Meg Lanning

On another day this would have been a World Cup-winning innings. In the hours after Healy's epic, Sciver did her best to replicate it, although the task always looked beyond England when the middle order fell away. Yet, because of Sciver, Australia could not quite rest easy until that final wicket fell.

A magnificent century from India's captain that sealed the series. Much like Healy's World Cup innings, the acceleration stood out, as Kaur, having reached her hundred from 100 balls, slammed 43 off her next 11 deliveries.
