Kerr's unbeaten innings makes her only the second woman to score a double hundred in ODI cricket.
White Ferns teenager Amelia Kerr has smashed her way into cricketing folklore with a world record knock.
She broke a 21-year-old record for the highest women's ODI score after going past Belinda Clark's 221, which the Australian scored against Denmark.
New Zealand's Amelia Kerr on Wednesday broke the record for the highest individual score in women's ODI in a match against Ireland in Dublin.
The Wellington-born player hit 31 fours and two sixes in her 145-ball innings to top the 229 not out Australia's Belinda Clark amassed against Denmark in Mumbai in 1997 - nearly three years before Kerr was born.
She also hit the second most boundaries in an ODI innings, behind Rohit Sharma's 33 in his 264. The partnership lasted from the 15th to the 48th over. Once Kerr was done demonstrating that she was wise beyond her years with the bat, she let a few of her legbreaks rip to cooly pocket a five-wicket haul and end Ireland's miserable week with their third successive defeat by 300-plus runs.
Kerr then completed a remarkable double with a five-wicket bag with figures of 5-17 from seven overs to help the White Ferns complete a three-ODI series sweep of Ireland. Post Amy's dismissal, Leigh Kasperek stepped up to the occasion slamming 113 off 105 balls.
Kerr's previous best with the bat had been 81 not out in the first ODI against Ireland on June 8, while her best bowling figures were 4-42 against Pakistan in November, 2016.
"New Zealand, who posted a world record for men and women when they scored 490 for four in the first one-day global, now head to England for a triangular Twenty20 series with the hosts and South Africa".
