Allen's record ton puts New Zealand in final

It was deja vu all over again for South Africa, the most dominant side of the 2026 T20 World Cup, until the knockout stage arrived. At the Eden Gardens, their old nemesis returned: the pressure, the occasion, and the crumbling under it. New Zealand, who only days ago had left their qualification fate in Sri Lanka's hands, once again turned streetwise and composed, taking charge of a big game with the kind of tactical intelligence that defines their cricket. They march on to the final at the Narendra Modi Stadium, chasing the one prize that slipped through their fingers in 2021.

This was nearly a mirror image of the group stage clash between these two sides 20 days ago, except the tables were turned dramatically. South Africa had won that encounter in similarly ruthless fashion, dismantling a middling New Zealand score without breaking a sweat. Now it was their turn to be denied a return to Ahmedabad. Finn Allen and Tim Seifert - soon to reunite at this venue as KKR teammates in next month's IPL - turned Eden Gardens into a personal playground and wiped out 84 runs of a 170-run target inside the Powerplay. The rest of the chase was pure showmanship. Allen plundered 10 fours and eight sixes in a 33-ball 100* - the fastest ton in T20 World Cup history that shattered the previous record by 14 balls and carried New Zealand home with a staggering 7.1 overs to spare, a margin that flattered to deceive just how utterly one-sided this had become.

The second half and the end of the game was a chastening experience for Markram. But the game, though, was effectively won much earlier when Mitchell Santner called correctly at the toss and his bowlers responded immediately on a slightly dry surface. Cole McConchie, a late injury replacement in the squad who had been retained in the XI as a specific match-up option, justified his selection - dismissing both left-handers Quinton de Kock and Ryan Rickelton off successive deliveries in the only over he bowled to leave South Africa reeling at 12 for 2.

South Africa should have been further in trouble when Lockie Ferguson had Aiden Markram chipping straight to mid-wicket, where Rachin Ravindra put down a straightforward chance. Markram and Dewald Brevis responded with intent, plundering 17 off a James Neesham over to drag the Powerplay total to a respectable 48 for 2.

But the momentum was short-lived. Ravindra atoned for his earlier lapse by drawing Markram into a horrible miscue down the ground, Daryl Mitchell completing a tumbling catch at long on that survived third umpire scrutiny. In walked David Miller, the man who had dug South Africa out of a similar hole against India. He too was immediately handed a lifeline when Glenn Phillips grassed a relatively straightforward chance at deep extra cover. But Miller couldn't survive that very Ravindra over. A cleverly disguised drop in pace did the job, the miscue this time finding long off with no such fortune.

When Brevis fell two balls later, South Africa were 77 for 5, and any semblance of hope was fast disappearing. Marco Jansen and Tristan Stubbs set about a measured rebuild, grinding their way to 113 for 5 at the end of the 16th over before finally cutting loose. Jansen and Stubbs plundered 15 off Matt Henry, then turned their attention to Neesham, each taking turns to clear the boundary in a brutal 22-run over that briefly suggested a competitive total was still within reach.

But Lockie Ferguson had other ideas. He returned to bowl Stubbs with a sharp leg cutter, ending the partnership just as it threatened to become decisive. Jansen pressed on alone with remarkable composure - two sixes propelling him to a 27-ball half-century - yet he found himself facing just a single delivery in the final over as South Africa fell well short of the 180-run psychological marker.

As it turned out, even another 50 runs might not have been enough. The New Zelaand chase began at a canter - 19 off the first two overs, a couple of half-chances falling agonisingly short of South African fielders. That was as close as Markram's men would come to stemming the tide. Allen and Seifert dismantled Jansen in the third over, then took 22 off Corbin Bosch to close out a Powerplay that had all but settled the contest.

Then it was all about the numbers. Seifert reached his half-century off 28 balls. Allen got there nine balls quicker in the very next over. Kagiso Rabada finally broke their 117-run stand in the 10th over, but the carnage was far from over. Allen blazed from 50 to 100 off just 14 balls, bringing up the milestone with the final scoring shot of the game, a fitting full stop on a famous victory, sealed with a performance to match.

Brief scores: South Africa 169/8 in 20 overs (Marcon Jansen 55*; Rachin Ravindra 2-29. Cole McConchie 2-9) lost to New Zealand 173/1 in 12.5 overs (Finn Allen 100*, Tim Seifert 58) by 9 wickets.
