Finn Allen etched his name into the history books on Wednesday night, striking the fastest-ever T20 World Cup century to propel New Zealand to a crushing victory over South Africa at Eden Gardens. In a performance described as "the perfect game" by skipper Mitchell Santner, the Black Caps dismantled the tournament's only previously undefeated side to book their place in the 2026 T20 World Cup final in Ahmedabad.
Chasing a modest target of 170, Allen reached his hundred in just 33 balls, shattering the record for the fastest century between two full-member nations. Alongside Tim Seifert (58), Allen ensured the chase was a mere formality, as New Zealand reached the target with 43 balls to spare.
Finn Allen’s innings was a display of pure, unadulterated aggression. Despite battling severe leg cramps that required multiple mid-innings treatments, the 26-year-old refused to relent. He hammered 10 sixes and 8 fours, striking at a rate that left the Proteas' vaunted pace attack looking shell-shocked.
The century was sealed in the 13th over when Allen launched Marco Jansen flat over mid-off for four, triggering a roar from the Eden Gardens crowd. Remarkably, Allen’s innings featured only four dot balls, a statistic that underscores the relentless pressure he applied to the South African bowlers.
Finn Allen’s 33-ball century is officially the fastest in the history of ICC Men's T20 World Cup knockouts. He surpassed the previous fastest 50 in a knockout (19 balls), previously held by Yuvraj Singh (20 balls vs AUS, 2007), and set a new gold standard for openers in the format.
While Allen took the headlines, the foundation for victory was laid in the second over of the match. Mitchell Santner made the "unlikely hero" call to introduce off-spinner Cole McConchie early. The move was a masterstroke, as McConchie removed South Africa's dangerous left-handed duo, Quinton de Kock and Ryan Rickelton, in consecutive deliveries.
South Africa never truly recovered from being 16/2. Although Marco Jansen (55 off 30)* and Tristan Stubbs (29) dragged the total to 169, it was at least 20-30 runs short of a competitive score on a surface that became faster under the evening dew.
Result: NZ (173/1 in 12.5 overs) beat SA (169/6 in 20 overs) by 9 wickets.
Player of the match: Finn Allen (100* off 33 balls).
SA heartbreak: The Proteas were undefeated (5-0) in the tournament until this match.
Milestone: Allen and Seifert now hold the record for the most partnership runs by a pair in a single T20I tournament.
A dejected Aiden Markram praised the New Zealand unit while acknowledging his side’s failure to adapt to the early spin trap.
Credit to their bowling unit. To get to 170 was a great effort, but when someone plays an innings like that (Allen), you don't often come out on the right side. Maybe we had to scrape our way to 190 to be in the game.Aiden Markram, South Africa captain
