It was a Wednesday evening where the Eden Gardens crowd didn’t really have a dog in the fight, and in New Zealand, it was ungodly hours of the morning. So how many truly invested folks experienced that surreal batting from Finn Allen?
Perhaps, the Allen household. “I’m sure my parents were up watching the whole game. Hopefully they’re proud,” Allen said with a smile.
At 9:56 PM IST, or 5:26 AM Auckland time, when Allen struck the last of his 10 boundaries, South African shoulders dropped with the weight of this reality and the New Zealand dugout erupted with hugs and handshakes. In the middle, Rachin Ravindra had his hands in the air in celebration before jogging over to embrace the opener who had just used a stage as gargantuan as a World Cup semifinal to smash the fastest T20I century against a full-member team, and the fastest-ever in the tournament’s rich history.
Those words tell you the story without sounding incredible enough—Allen had just scored a T20I 100 in 33 balls.

The Record-Breaking Numbers
Allen needed just 33 balls for his hundred against South Africa, the quickest in the tournament, bettering Chris Gayle’s 47-ball record by 14 balls. It’s also the fastest in all T20 World Cup matches (men or women), surpassing Deandra Dottin’s 38-ball century from 2010, and the fastest for New Zealand in T20Is, beating Glenn Phillips’ 46-ball effort.
Fastest T20 World Cup Centuries
| Player | Balls | Opposition | Year |
|---|---|---|---|
| Finn Allen | 33 | South Africa | 2026 |
| Deandra Dottin | 38 | South Africa | 2010 |
| Chris Gayle | 47 | England | 2016 |

Allen’s hundred is the joint-fastest for a Full Member team in T20Is alongside Sikandar Raza’s against Gambia, and the fastest against a Full Member team, beating the 35-ball centuries by David Miller and Rohit Sharma from 2017.
The Innings Breakdown
Besides 10 fours, there were eight sixes—88 of his 100 came in boundaries with just three dot balls. To grasp the improbability, you only have to look at how differently it began before gathering pace.

The Slow Start
Five overs into the chase, New Zealand had 62 for 0. But it was still about what Tim Seifert was doing to throw the South African quicks off their lines. As Allen would later attest, he had the best seat in the house for that carnage. Forty-one of that 62 came off Seifert’s bat and Allen had only played nine of the 30 deliveries.
The Switch Flips
As Aiden Markram brought on Corbin Bosch to finish the Powerplay, the switch flicked. Bosch started with a length loosener outside off-stump and watched Allen smash it over backward point, his bat completing a full, swift arc. New Zealand wiped out nearly half their target (84/0 in 6 overs, target: 170) and Allen overtook Seifert after a 22-run over.

The 84 for 0 was New Zealand’s highest T20 World Cup powerplay and the fifth-highest for any team. It’s also the highest in a knockout game in this competition’s history.
No Mercy
In the ninth over, Allen reached a 19-ball fifty—the fastest in a T20 World Cup knockout, beating Yuvraj Singh’s 20-ball effort from 2007. It’s also the fastest for New Zealand at the T20 World Cup.
Kagiso Rabada broke Seifert’s stumps, giving South Africa a brief pause from retrieving balls from beyond the boundary. But Rachin Ravindra found himself on the best seat in the house, watching Allen flay Markram’s bowlers. New Zealand needed 46 off 60, but took just 16 deliveries to finish it.
Tournament Dominance
Allen hit 20 sixes in this World Cup, a tournament record surpassing Shimron Hetmyer’s 19. His 18 boundaries are joint-highest in a T20 World Cup innings with Brendon McCullum’s 18 from 2012. Those boundaries fetched him 88 runs, joint-highest with Gayle’s 117 in 2007.
Allen became the first to score a hundred in a men’s T20 World Cup knockout match, beating Tillakaratne Dilshan’s unbeaten 96 from 2009. His three T20I hundreds tie him with Colin Munro for New Zealand’s joint-highest.
The Allen-Seifert Partnership
The 463 partnership runs between Allen and Seifert in this World Cup are the most by any pair in any men’s T20I series or tournament. They also completed 1000 partnership runs in T20Is, with the highest run rate among all 42 pairs with 1000-plus runs.
The KKR Teaser
For Allen, it goes down as an unforgettable night where he carried his team into an ICC final. And for those in the galleries, it doubled as a tantalising teaser—a glimpse of what could come in less than a month from now, when he swaps the black jersey for purple and gold.
The Eden Gardens crowd, ostensibly neutral, found themselves captivated by Allen’s assault. The 39,000 fans cheering on as he reached his century with the winning shot weren’t just witnessing history—they were getting a preview of their new Kolkata Knight Riders opener.
Allen and Seifert, both KKR teammates, will reunite at this famous venue in the IPL. Their partnership of 117 off 55 balls in the semifinal showcased what KKR fans can expect: aggressive, fearless cricket from ball one.
