Temba Bavuma made a magnificent century as South Africa produced a record run chase to beat England by five wickets and seal an ODI series victory.
Jos Buttler top scored with an unbeaten 94 from 82 balls, while Harry Brook (84) and Moeen Ali (51) struck quickfire half-centuries to get the tourists up to an imposing 342-7 at Mangaung Oval on Sunday.
That was not enough to set up a series decider, though, as captain Bavuma (109 off 102) crafted his first international century for a year as the Proteas pulled off the highest successful ODI run chase in Bloemfontein.
David Miller finished off the job with 58 not out from 37 balls as South Africa boosted their chances of securing direct qualification for the World Cup in India this year, consigning England to a fifth consecutive loss in this format.
Jason Roy fell for only nine after scoring a century in the first ODI on Friday and Dawid Malan (12) also failed, but Brook and Buttler put on 73 for the fourth wicket.
Brook raced to a half-century before falling to Aiden Markram and Moeen kept England ticking along nicely with his skipper until he played on to a delivery from Anrich Nortje (2-64).
Buttler and Sam Curran (28 off 17) cut loose as the world champions took 60 off the last four overs to seemingly take the upper hand.
Bavuma led by example to get his side off to a blistering start, combining with Quinton de Kock – who took a blow on the wrist while keeping but did not appear to be hampered – for 77.
Olly Stone (2-48) got rid of De Kock but Bavuma was in great touch with support from Rassie van der Dussen (38) as England – who left Jofra Archer out the paceman's long-awaited return in the opening match – were unable to halt the flow of runs.
Bavuma fell scooping Curran into his stumps soon after bringing up a sublime third ODI hundred to end a stand of 97 with Van der Dussen, who then became Adil Rashid's (2-72) second victim.
Heinrich Klaasen (27) failed to build on a start, but Miller and Marco Jansen (32no off 29) got South Africa home with five balls to spare – the left-hander fittingly winning it by clattering Chris Woakes for six.
Brook and Buttler pummel Proteas attack
Brook has made a great start to his international career and showed his class in only his second ODI after being dismissed for a duck on debut two days earlier.
He struck four sixes and seven fours before Buttler provided a late onslaught, getting his side up to a big total with support from Moeen and Curran.
The skipper cleared the rope on three occasions and struck eight boundaries, shifting through the gears in explosive fashion.
Brilliant Bavuma sets up record chase, Miller delivers again
Bavuma had not reached three figures for his country since his hundred against India last January, but he ended that wait in style.
With South Africa battling to seal their World Cup spot for the tournament in India, Bavuma batted beautifully to lay the platform at the top of the order.
Miller thrives on the responsibility of being the finisher and he delivered once again, hitting three sixes as South Africa bettered their previous best ODI run chase on this ground of 274-4 against Australia in 2020.
