Records tumbled in the Women's World Cup final in Christchurch on Sunday as a magnificent 170 from Alyssa Healy helped Australia secure a 71-run victory over a valiant England. After Australia amassed a daunting 356-5, defending champions England, faced with a record target, kept up the run rate but ran out of wickets to be dismissed for 285 in the 44th over, with Nat Sciver unbeaten on 148. The victory continued Australia's dominance of the 50-over format with their seventh title from 12 World Cups and extended their one-day international record to 38 wins from 39 matches over the past four years. "We have been extremely consistent over a long period of time," Australia captain Meg Lanning said. "It's been a long time coming. I think we deserved a victory today." Against England, Australia lost the toss but nothing else. England captain Heather Knight put Australia into bat, noting her side had bowled "outstandingly well" at Hagley Oval, but Australian openers Healy and Rachael Haynes were not listening. They showed patience, scoring a sedate 26 off the first eight overs before Healey went on the rampage, paying the bowlers no respect as she pounded all points of the boundary with 26 fours. Her 170, off just 138 deliveries, was the highest score in a women's or men's World Cup final, the highest score in this tournament and contributed to her tournament record of 509 runs, eclipsing the 497, set by Haynes earlier in the same innings. The Healy and Haynes 160-run opening stand was a record partnership for any wicket in a World Cup final, but England could have claimed both wickets in the 21st over, with Australia still in the 90s, when Healy and Haynes were dropped off the bowling of Kate Cross. It took Australia 22.2 overs to bring up their first 100, 13 more overs for the second hundred but just nine overs for the third, helped by England returning to the poor fielding which had plagued their start to the World Cup when they lost their first three games. When Haynes went for 68, Beth Mooney joined Healy in a 156-run partnership before Healy's extraordinary innings ended in the 46th over when she missed an Anya Shrubsole delivery and was stumped. "It's a lot of fun watching Healy bat, and it takes the pressure off me, she was phenomenal," opening partner Haynes said. "It's one of the best knocks I've ever seen and she saved it for the big occasion." Mooney quickly followed for 62 as Australia lost four wickets in a push for runs over the last four overs, with Elysse Perry finishing unbeaten on 17 after coming in at No 7 on her return from injury. Anya Shrubsole was the one England bowler to perform with credit with three for 46 off her 10 overs – the figures inflated by the final over which cost 15 runs. England made a determined effort to stay within reach of the required run rate, but were hampered by wickets falling at regular intervals. Sciver's 148 was the second highest score in a Women's World Cup final, but the next best for England was 27 by opener Tammy Beaumont. "Unbelievable from Nat," Knight said. "The skill against spin and seam, unfortunately we couldn't have someone stand with her in the middle." For Australia, Jess Jonassen took 3-57 and Alana King finished with 3-64. But the headlines belong to Healy, who was named both player of the match and the tournament. "It's not sunk in yet, a special game of cricket," Healy said. "Couldn't ask for anything more. I am proud of our batting unit. We have done it all but to do it on the biggest stage, I never imagined in my wildest dreams."
