Tarouba (Trinidad) | South Africa exorcised their agonising semifinal jinx through an exceptional spell of pace bowling as they walloped an emotionally drained Afghanistan by nine wickets to enter their first-ever T20 World Cup final here.
They will face the winners of the second semifinal between India and England in the title clash, but the Afghans will go home with their heads held high after a stirring run in the tournament.
Marco Jansen (3/16) Kagiso Rabada (2/14) and Anrich Nortje (2/7) ripped the soul out of the Afghanistan top-order while bundling them out for a paltry 56 in just 11.5 overs after being invited to bowl.
Despite the early departure of Quinton de Kock, bowled through the gate by impressive pacer Fazalhaq Farooqi, the Proteas had little trouble in reaching 60 for one in 8.5 overs.
Reeza Hendricks (29 not out), who put up his highest score in this event, and skipper Aiden Markram (23 not out) navigated them safely to the shores of victory as they have finally freed themselves from the painful tag of chokers in global events.
Afghanistan have given their everything to reach the World Cup semifinal, and in the crucial clash they were left with no energy, and produced a nothing effort that belied their doughtiness until now.
It affected their batting as they looked unusually edgy against the South African pacers, who summoned a spell from hell.
They reduced the Afghans to 28 for five inside the Powerplay and there was no coming back from that depth as they crashed to their lowest total in a T20 International.
Their 56 was also the lowest total in a T20 World Cup semifinal clash.
Once reduced to 28 for six, Afghanistan could not even offer a smidgeon of fight as their dream of reaching a maiden World Cup final was squashed even before it began.
While the South Africa pacers were on the money, the Afghan batters too should cope some blame for being edgy on a pitch that hid no evils apart from those deliveries that kicked up from a length.
Opener Rahmanullah Gurbaz was the first to perish, chasing Jansen's delivery outside the off-stump to give Reeza Hendricks an easy catch at slip.
The dismissal of in-form Gurbaz seemed to inject doses of panic in the Afghanistan line-up, and Gulbadin Naib was consumed by a lovely in-coming delivery by Jansen.
But the next two dismissals were a combination of bowler's brilliance and batters' irrationality.
Ibrahim Zadran, on whom a lot was riding for the Afghans, did not move his feet at all against a Rabada delivery that came back a bit. There was enough room for the ball to sneak past the bat and pad to rattle Zadran's leg-stump.
Three balls later in the fourth over, Mohammad Nabi's dismissal was along similar lines and the only difference was that Rabada disturbed the off-stump this time.
Nortje joined the party with the scalp of Azmatullah Omarzai, whose slash found Tristan Stubbs in the deep.
Gurbaz, Zadran and Omarzai have been the leading run-makers for Afghanistan in this ICC showpiece, but on the crucial day all they could manage was a paltry 12 runs between them.
Skipper Rashid Khan, who could have made some valuable runs, chose to expose all his stumps to Nortje to see the one close to his legs getting cartwheeled across the field.
Leg-spinner Tabraiz Shamsi (3/6) applied the coupe de grace on Afghanistan batting line with two wickets in one over, jettisoning Karim Jannat and Noor Ahmad
