Dale Steyn produced a stunning display of death bowling to rescue South Africa and secure a two-run victory over New Zealand in the World Twenty20.
The master paceman finished with figures of 4-17 and held his nerve when the Black Caps needed seven to win from the final over and three off the last delivery, which saw Steyn run out Ross Taylor to end the match.
Without his intervention the Proteas were staring at a second successive defeat and near-certain elimination.
The South Africa innings started quietly, reaching 39 for two from the powerplay overs, and seemed to be heading for trouble when AB de Villiers was castled by Nathan McCullum.
That brought Hashim Amla and Duminy together and the pair played important, but entirely different knocks.
Amla was circumspect as he scored at around a run-a-ball throughout his innings of 41, falling in bizarre fashion when his drive down the ground struck his partner's bat and looped up to give Corey Anderson an unlikely return catch.
Duminy, in contrast, struck 10 fours and three sixes en route to an unbeaten 86.
His fireworks helped South Africa post 170 for six - a considerably higher total than once seemed likely.
New Zealand's response began with promise, Kane Williamson and Martin Guptill putting on 57 in seven overs before the latter fell to Albie Morkel for 22.
Talismanic skipper Brendon McCullum was stumped chasing an Imran Tahir wide in vain but Williamson brought up his 50 from 31 balls to keep things ticking.
He found much-needed support in Taylor, who clubbed three consecutive sixes off Morne Morkel to take a big chunk out of the target on his way to 68.
But the return of Steyn had the desired effect as Williamson was well caught by De Villiers, while Luke Ronchi and Nathan McCullum fell during the last over before the superstar quick's final flourish acoounted for Taylor.
