Tammy Beaumont struck a stunning century as England stormed to their fifth-highest ever one-day international total at Leicester on the hottest day of the year to take an unassailable lead in the multi-format series with South Africa.
Beaumont’s 119 from 107 balls set the platform for a third successive ODI success which sees England lead the series 8-2 heading into the three T20 internationals that begin on Thursday with two points available from each game.
England racked up 371 for seven from their 50 overs and it was always going to be too big a chase for the tourists who lasted 45.4 overs in making 262 with some lusty late hitting from Marizanne Kapp (62) and Chloe Kyron (70).
England were put in to bat by South Africa captain Sune Luus despite the heat, and the opening pair of Beaumont and Emma Lamb put on 149 before the loss of the first wicket in the 23rd over.
