England levelled the three-match T-20 series against South Africa on Friday as a crashing 39 off 11 balls by Moeen Ali helped win a thriller in Durban.
The tourists posted an imposing 7-204 and then held their nerve to win by two runs as South Africa were limited to 7-202 in reply, despite 65 off 22 by Quinton de Kock.
England had a great start through Jason Roy (40) and Johnny Bairstow (35) but were then bogged down somewhat before Ben Stokes, who finished on 47 not out, and Moeen, who played a series of audacious shots, helped them push on to their formidable tally.
South Africa looked capable of pulling off a victory when De Kock smashed eight sixes as they reached 92 without loss in the seventh over but when he was caught by Stokes off Mark Wood, the game looked to swing England's way.
However, a spirited late flurry by Rassie van der Dussen (43no) left the hosts, who won the first match by one run, needing 15 off the final over.
The key moment came off the second-to-last ball of the game when Tom Curran had Dwaine Pretorius out lbw with South Africa still needing three. Pretorius reviewed the decision, which was confirmed by fine margins.
Bjorn Fortuin tried to ramp the last ball for four but was caught by Adil Rashid as England came through to set up an exciting decider in Pretoria on Sunday.
