England 197 (Wyatt 63*) beat New Zealand 169 (Halliday 29, Dean 4-36, Cross 3-43) by 13 runs (DLS method)
Youth and experience combined superbly to deliver England an unlikely 13-run victory over New Zealand in Worcester for a 2-0 lead in their ODI series.
Young off-spinner Charlie Dean, playing just her second international match, claimed 4 for 36 from eight overs as England defended a paltry total, the visitors falling short in pursuit of a revised target of 183 from 42 overs under the DLS method when they were bowled out for 169.
Danni Wyatt's unbeaten half-century upon returning to England's one-day side limited the damage for the hosts after New Zealand won the toss and sent them in, then bowled them out for 197 halfway through the 44th over.
Wyatt became the seventh woman to make 200 appearances for England when she came in at No.7 for the resting allrounder, Katherine Brunt. It was Wyatt's 78th ODI but first since February in New Zealand, having been overlooked for the 50-over leg of India's tour although she regularly opened with Tammy Beaumont in T20Is through the summer.
Interestingly, Wyatt was involved in a messy run-out with the player she is in most direct competition with for a World Cup berth. With England struggling desperately at 85 for 5, Wyatt and Lauren Winfield-Hill put on 33 runs together before a mix-up resulted in both being stranded at the non-striker's end. Bowler Leigh Kasperek threw the ball, initially fired in from square leg, to wicketkeeper Katey Martin, who whipped off the bails, sending Winfield-Hill on her way for 39 after Wyatt had retreated halfway through the second run and got back inside the crease with her batting partner right behind her.
Wyatt struck four fours on the way to her score, plus two sixes off Hannah Rowe, while Farrant chimed in with three fours of her own from No. 11, eventually falling for 22.
New Zealand ended the Powerplay 44 for 1, compared to England's 59 for 1, Kate Cross having had opener Suzie Bates caught by Wyatt for 28 in the ninth over.
When England then took two wickets in three balls via Sophie Ecclestone and Cross, it looked like the visitors might mirror their collapse. Indeed, they slid to 85 for 4 after Cross had Amy Satterthwaite caught behind, but then Sophie Devine and Brooke Halliday steadied, pushing the score to 111 for 4 when rain halted play after 24 overs, at which point the White Ferns were comfortably ahead on the DLS method.
When play resumed, New Zealand needed 72 off 18 overs but then Nat Sciver claimed the crucial wicket of Devine, bowled through the gate without adding to the 28 she had before the rain interruption to keep England in with a chance.
Dean, who had made her international debut just three days earlier in Bristol, returned to the attack, having conceded two swept fours in one over to Devine. After Martin sent her third ball back to the boundary through third, Dean responded immediately with a gem of a delivery that beat the outside edge and clattered into the stumps.
Despite their tail wagging in the first ODI, wickets became the most pressing issue for New Zealand when Dean struck again to remove Rowe lbw. At that point, New Zealand needed 48 off 63 balls but they only had three wickets in hand.
Dean then drew Brook Halliday out of her crease with a wider delivery, which Amy Jones snaffled for a stumping to swing the momentum firmly in England's favour.
Dean had her fourth trapping Leigh Kasperek lbw and then Farrant backed up her contribution with the bat to claim the final wicket, Lea Tahuhu caught at cover by Heather Knight.
Earlier, Beaumont struck three boundaries off Devine's first over to cruise to 12 off six balls but her knock ended when she misjudged Devine's sixth ball, the 12th of the innings, shouldering arms to one that nipped back slightly to take the top of off stump.
Rowe entered the attack and struck first ball, drawing Knight into a drive with one that swung away late and found an edge, which Martin collected behind the stumps.
Rowe was finding subtle but devastating movement and she made it 2 for 2 with her seventh ball as Sciver's search for runs continued. Sciver, who has only once reached double-figures during New Zealand's tour with 14 in the opening T20I, fell for 1 when she drove Rowe to Maddy Green at cover.
Jones fell cheaply when Devine brought herself back into the attack and struck with an inswinger, taken by Halliday at midwicket as England slumped to 68 for 4.
Sophia Dunkley's dismissal, chipping Tahuhu to substitute fielder Hayley Jensen at short midwicket for just 11 had England in dire trouble until the Wyatt-Farrant rearguard rescued them.
