England 137 for 4 (Beaumont 34, Bouchier 33, Dercksen 2-22) won South Africa 135 (Tryon 45, Dean 4-45, Ecclestone 3-27, Filer 3-32) for six wickets
Then, however, came a drinks break at the end of the 16th over, and what followed was a surprising mid-innings meltdown.
Ecclestone herself was called into action four balls later, when Wolvaardt, whose cover driving had once again been the feature of her innings, this time misjudged the length and slid in on her own stumps for 35, while staying back in the fold. .
At 76 for 5, South Africa were drunk and two balls into Dean’s next over, they were almost out of the count. Nadine de Klerk made a horribly off-balance cut, which Heather Knight slipped and collected via a deflection off the goalkeeper’s gloves, and then Sinalo Jafta lamely advanced and was pinned in front of the cross and leg of the first ball.
A review could not save her, and Dean had become only the third England bowler to take an ODI hat-trick in women’s cricket, after Carol Hodges against Denmark in 1993 and, more recently, Clare Connor against India in 1999. She seemed bewildered when asked about the achievement during the inning break and later admitted in the postgame presentation that the moment had slipped her mind.
The spinners, however, would not refuse for long. Ecclestone found some extra spin and bounce to beat Tryon through a strong take from Beaumont at short leg, and then cleaned up the innings with 18 unused overs when Ayanda Hlubi was bowled for 6.
In response, England’s chase was started by Beaumont and Bouchier, whose opening stand of 69 in 12 overs broke the requirement.
Both were eventually removed by the aggressive Dercksen, whose use of the short ball induced two spongy pulls, Bouchier to midwicket and Beaumont to the keeper, and when Heather Knight was caught lbw for 7 by Kapp, there was the threat of a wobble at 82 for 3 .
However, Danni Wyatt-Hodge and Nat Sciver-Brunt put the contest beyond doubt with a fourth-wicket stand of 47, and although de Klerk got a consolation lbw in the final over, two fours from Amy Jones sealed the deal .
