New Zealand produced one of the most electrifying performances in T20 history as Finn Allen smashed a record-breaking 33-ball century to power the Black Caps into the ICC Men’s T20 World Cup 2026 final. In a high-stakes semi-final at Eden Gardens, Allen’s unbeaten 100 dismantled South Africa’s bowling attack and sealed a commanding nine-wicket victory with 43 balls to spare.

Chasing 170, New Zealand stormed to 173/1 in just 12.5 overs, snapping the Proteas’ unbeaten run in the tournament and booking their second T20 World Cup final appearance after 2021.

Finn Allen’s Record-Breaking 33-Ball Century

Finn Allen’s innings will be etched into T20 folklore. The explosive opener reached his hundred in just 33 balls — the fastest century in T20 World Cup history and the joint third-fastest in all T20 internationals. He surpassed the previous tournament record set by Chris Gayle, who had scored a 47-ball century against England in 2016.

Allen’s knock included 10 fours and eight sixes, a breathtaking display of power-hitting and precision. The century is also:

• The fastest ever against a Full Member nation in T20Is.

• The joint-fastest T20I ton by a Full Member team batter, alongside Sikandar Raza’s hundred against Gambia in Nairobi in 2024.

From 76 to 100, Allen needed just five deliveries from Marco Jansen, turning what seemed like a promising day for the South African all-rounder into a nightmare. Allen’s first fifty came off 19 balls — already the joint-fastest of this edition — but he astonishingly shifted gears to score the second half of his century in only 14 balls, even taking a brief medical time-out in between.

Planted firmly on the front foot, Allen hit through the line with brutal efficiency as the dew-set pitch made stroke-play easier. The ball came sweetly onto the bat, and he simply muscled it to all parts of the ground.

A 117-Run Opening Stand That Decided the Match

While Allen stole the headlines, Tim Seifert played the perfect supporting role. The Kiwi openers, both recent recruits for the Kolkata Knight Riders, unleashed carnage in front of a stunned crowd.

Seifert struck 58 off 33 balls, smashing seven fours and two sixes. Together, the duo added 117 runs in just nine overs — a partnership that effectively ended the contest within the powerplay.

New Zealand’s powerplay score of 84/0 was the second-highest of the tournament, just two behind India’s 86/1 against Namibia. The sixth over, bowled by Corbin Bosch, yielded 22 runs, with Allen hammering four boundaries and a six in succession.

Key milestones in the chase:

• 50 runs in 4.4 overs (via Seifert’s six off Kagiso Rabada).

• 100 runs in 7.5 overs.

• Seifert’s fifty in 28 balls.

• Allen’s second tournament fifty in just 19 balls.

• 150 runs reached in 12.1 overs.

Rabada (1/28) eventually broke the opening stand, bowling Seifert in the 10th over. But by then, New Zealand were 124/1 and cruising. Allen remained unstoppable, finishing with three fours and two sixes in the final five balls to carry his team over the line.

South Africa’s Fightback: Jansen and Stubbs Rescue a Faltering Innings

Earlier in the day, South Africa had posted 169/8 after being asked to bat first. The total, while competitive, ultimately proved well below par.

The Proteas were in deep trouble at 12/2 after off-spinner Cole McConchie struck twice in the second over, dismissing Quinton de Kock and Ryan Rickelton off successive deliveries. New Zealand’s tactical deployment of spin early paid immediate dividends.

Captain Aiden Markram added 43 runs with Dewald Brevis before falling to a stunning diving catch by Daryl Mitchell off Rachin Ravindra. Brevis contributed 34 but perished attempting to accelerate, chipping James Neesham to cover.

At 77/5 by the halfway stage, South Africa were reeling. That’s when Marco Jansen and Tristan Stubbs mounted a recovery.

The pair added 73 runs for the sixth wicket in 48 balls:

• Jansen scored 55 not out off 30 balls, hitting two fours and five sixes.

• Stubbs made 29 off 24 balls with two fours and a six.

Jansen’s powerful hitting, including back-to-back sixes off Lockie Ferguson to reach his half-century, gave South Africa late momentum. The 18th over, bowled by Neesham, leaked 22 runs as Jansen and Stubbs attacked with intent.

However, despite Jansen’s rearguard action, his bowling figures (0/53 in 2.5 overs) were severely punished during the chase — particularly by Allen’s devastating assault.

New Zealand’s Bowlers Lay the Foundation

Before Allen’s fireworks, it was New Zealand’s disciplined bowling that set up the victory.

Key contributors:

• Cole McConchie: 2/9

• Rachin Ravindra: 2/29

• Matt Henry: 2/34

• Lockie Ferguson: 1 wicket

• James Neesham: 1 wicket

The spinners executed a tactical masterclass on a slightly slower surface. McConchie and Ravindra effectively “chokeslammed” South Africa’s star-studded top order, exploiting early grip and turn before dew later made batting easier.

The only phase where New Zealand briefly lost control was during Jansen’s late surge. But overall, their bowling unit kept the Proteas under consistent pressure.

What’s Next: India vs England in the Second Semi-final

New Zealand now await the winner of the second semi-final between India and England at the Wankhede Stadium in Mumbai.

India, unbeaten in the group stage, have had their share of batting inconsistencies despite being pre-tournament favourites. Tactical adjustments — including promoting Sanju Samson to open and shifting Tilak Varma to number five — have added balance. With all-rounders Hardik Pandya, Shivam Dube and Axar Patel providing depth, India bat deep.

England, led by Harry Brook, have endured a roller-coaster campaign. After a narrow win over Nepal and a heavy defeat to West Indies, they regrouped to advance unbeaten through the Super Eights.

Key battles to watch:

• England’s spin trio of Adil Rashid (11 wickets), Liam Dawson (10), and Will Jacks (7) against India’s left-heavy batting order.

• Jofra Archer and Jamie Overton’s pace and short-ball threat.

• India’s reliance on Jasprit Bumrah, who made his name at this very venue.

• The form of mystery spinner Varun Chakravarthy, who is seeking redemption after a rough Super Eights phase.

If India triumph, the final will be a repeat of last year’s Champions Trophy title clash.

A Night Eden Gardens Will Never Forget

For Eden Gardens, this semi-final will be remembered as the night Finn Allen redefined power-hitting. His 33-ball hundred wasn’t just a statistical marvel — it was an exhibition of dominance rarely seen in knockout cricket.

New Zealand, led by Mitchell Santner, now march into the final brimming with confidence. And as Allen’s star continues to rise, the cricketing world has a new name etched firmly into T20 history.
