Finn Allen smashes incredible 33-ball century

Men's T20 World Cup semi-final, Kolkata

South Africa 169-8 (20 overs): Marco Jansen 55* (30); Ravindra 2-29

New Zealand 173-1 (12.5 overs): Allen 100* (33); Tim Seifert 58 (33)

New Zealand won by nine wickets with 43 balls remaining

Finn Allen struck the fastest century in T20 World Cup history as a staggering performance by New Zealand demolished 2024 runners-up South Africa by nine wickets and booked the Black Caps a place in Sunday's final. Chasing 170 after a 27-ball half-century from Marco Jansen had rescued South Africa from 77-5, Allen bludgeoned 100 not out from 33 balls, including 10 fours and eight sixes, as a ruthless New Zealand romped to victory with 43 balls to spare.

Allen bettered Chris Gayle's 47-ball century against England in 2016 by 14 deliveries, with his knock also the joint third-fastest century in men's T20 internationals. Tim Seifert thrashed a brisk half-century of his own (58 off 33) as New Zealand's openers put on 117 runs (55 balls) for the first wicket before Allen kicked into overdrive. He smacked 42 runs off just 11 deliveries to dominate his 56-run stand with Rachin Ravindra, including dispatching Jansen for five consecutive boundaries to complete an emphatic win.

South Africa were previously unbeaten at this tournament, including a seven-wicket victory over the Black Caps in the initial group phase, but faltered with the bat after losing the toss. They lost Quinton de Kock (10) and Ryan Rickelton (0) to consecutive deliveries in the second over to slump to 12-2 while Aiden Markram (18 off 20) and David Miller (6) both failed to capitalise on being dropped on three. When Dewald Brevis (34 off 27) chipped a routine catch to Mitchell Santner in the covers in the 11th over, it felt like game over for South Africa but Jansen found a stable partner in Tristan Stubbs (29 off 24) before bursting into life in the final five overs to propel the Proteas from 108-5 to 169-8.

Jansen put on 73 runs (48 balls) for the sixth wicket with Stubbs and struck five sixes in his unbeaten 55 off 30 balls. However, it quickly proved nowhere near enough, with New Zealand never looking back after their destructive openers took the opening six overs for 84 runs - a powerplay score bettered only once in this tournament, by India against Namibia.

Going into this match, South Africa were the favourites not only to beat New Zealand but also to end their wait for a maiden T20 World Cup title. The unbeaten Proteas had topped Group D, the so-called group of death, before brushing aside India and West Indies in the Super 8s to book their spot in the knockout stages with a match to spare. The tag of favourites was something they were more than happy to wear, head coach Shukri Conrad said on Wednesday, but over the course of 32.5 chastening overs, the memories of Sydney in 1992, Kolkata in 1999, Melbourne in 2015 and Barbados in 2024 came flooding back.

Their usually reliable top order, which included the third-highest run-scorer in the competition in Markram, faltered for the second consecutive match, undone by spin as had happened against Zimbabwe. It was Sikandar Raza who accounted for their openers in the powerplay on Sunday. In Kolkata, Cole McConchie struck with back-to-back deliveries in the second over as Quinton de Kock and Ryan Rickelton gifted routine catches to Lockie Ferguson and Allen, respectively, while Ravindra accounted for Markram and Miller: South Africa 77-4.

With the ball, tasked with defending a below-par 169, their bowlers were torn apart, none more so than the usually reliable Jansen, who leaked 29 runs from his two powerplay overs. Of the 12.5 overs New Zealand needed to complete their rapid chase, only three cost fewer than 10 runs. South Africa have now lost three of their four men's T20 World Cup semi-finals and four out of five knockout matches. In the 50-over tournament, all five of their semi-final outings have ended in defeat. They might have broken their duck with victory in the World Test Championship final last June, but their reputation as chokers remains.
