In the 2026 T20 World Cup semifinal at Eden Gardens, Finn Allen played an inning that changed the record books in just over half an hour of batting. Chasing 170 against South Africa, the New Zealand opener smashed an unbeaten 100 from only 33 balls, lifting his team to a nine‑wicket win with 43 balls to spare. Meanwhile, he became the fastest batter to score a century in T20 World Cup history.
Finn Allen now sits at the top of a very special list: the fastest hundred in T20 World Cup history, a blazing 33‑ball ton that has pushed Chris Gayle’s famous record down to second place. Along with Allen, Gayle, Harry Brook and Brendon McCullum complete a power‑packed top‑five that shows how quickly a T20 game can turn once a batter finds his range.
Allen’s knock contained a mix of clean straight hits, fierce pulls and lofted shots over cover that kept the fielders almost out of the game. He struck 10 fours and 8 sixes, and once he got going, South Africa’s bowlers struggled to find any area where they could tie him down.
Finn Allen’s 33-ball ton stands out vs South Africa (2016)
Before this match, Chris Gayle’s 47‑ball hundred against England in 2016 held the mark for the fastest century in men’s T20 World Cups. Allen went past that by a massive 14 balls, making his effort not just a new record but a huge jump in speed at this level.
This 33‑ball hundred is not only the quickest in T20 World Cup history, but also the fastest century ever scored against a Full Member team in T20 internationals and sits joint third on the all‑time T20I list. It came in a knockout game as well, which made the innings even more eye‑catching given the stage and the stakes for both sides.
Chris Gayle’s 47-ball storm vs England (2016)
Before Allen, the T20 World Cup’s speed king was Chris Gayle, whose 47‑ball hundred against England in Mumbai during the 2016 edition became an instant classic. Opening the innings for West Indies while chasing 183, Gayle finished unbeaten on 100 and took his team home with 11 balls left.
He hit 11 sixes and 5 fours that night, clearing the ropes with ease and forcing England’s attack into defensive mode very early. That innings made him the first man to score two T20 World Cup hundreds and set a benchmark that lasted for a decade until Allen’s semifinal blitz.
Gayle’s first T20 World Cup ton vs South Africa (2007)
Gayle’s first entry in this list goes back to the opening match of the inaugural T20 World Cup in 2007 against South Africa. Batting first, he reached his century in 50 balls and finished with 117, lighting up Johannesburg with one of the earliest examples of a truly big T20 score.
Even though West Indies could not defend their total on that occasion, Gayle’s 50‑ball hundred showed the format what was possible at the top of the order. It set a standard for aggressive opening play, and it is still remembered as one of the defining knocks of the first T20 World Cup.
Harry Brook enters the list in 2026
England’s Harry Brook became one of the newest names in this elite club during the 2026 T20 World Cup in Kandy. Leading England against Pakistan, Brook scored a crucial hundred off 50 balls in a tense chase of 165.
England were in real trouble at 58 for 4, but Brook held firm, struck ten fours and four sixes, and guided his side to a two‑wicket win that also sealed a place in the semifinals. His 50‑ball century is recorded as one of the joint second‑fastest hundreds in men’s T20 World Cups, placing him alongside some of the most aggressive batters in the format.
Brendon McCullum’s 51-ball carnage vs Bangladesh (2012)
Brendon McCullum was one of the early stars of T20 cricket, and his 51‑ball hundred against Bangladesh in the 2012 T20 World Cup underlined why. Playing for New Zealand, the wicketkeeper‑batter went on to score 123 in that game, which remained one of the highest individual scores in the tournament for years.
McCullum attacked from the start, used the crease well, and targeted both pace and spin with equal success. His 51‑ball century still holds a place among the top five fastest hundreds in T20 World Cup history and helped shape the attacking style that many modern openers now follow.
Top five fastest T20 World Cup hundreds
| Rank | Batter | Balls for 100 | Match | Edition |
| 1 | Finn Allen | 33 | South Africa vs New Zealand | 2026 |
| 2 | Chris Gayle | 47 | West Indies vs England | 2016 |
| 3 | Chris Gayle | 50 | West Indies vs South Africa | 2007 |
| 4 | Harry Brook | 50 | England vs Pakistan | 2026 |
| 5 | Brendon McCullum | 51 | New Zealand vs Bangladesh | 2012 |
Allen’s 33‑ball effort clearly stands alone in this table as the only T20 World Cup hundred scored in close to five overs of batting. However, the presence of Gayle twice, along with Brook and McCullum, shows that this list mixes both modern stars and earlier T20 trailblazers.
Looking across this list, one clear theme is the steady shift towards higher scoring rates at the top of the order. The earliest hundred here, Gayle’s 50‑ball ton from 2007, already felt extremely fast for its time, but in less than 20 years that bar has been lowered by 17 balls at World Cup level.
Modern T20 teams build their line‑ups around batters who can clear the boundary from ball one and maintain high strike rates across the innings. With better bats, more data on match‑ups, and bolder game plans, innings like Allen’s 33‑ball hundred or Brook’s 50‑ball rescue act have become central to how teams plan their campaigns.
Big‑match stage, bigger scores
Another point that stands out is that many of these knocks came in high‑pressure games: two in semifinals or qualification deciders and others in opening matches of major tournaments. Yet, instead of starting slowly, these batters chose to attack from the start and kept going even as the fielding sides tried different plans.
From Gayle’s early power hitting to McCullum’s fearless strokeplay and now Allen and Brook’s 2026 heroics, T20 World Cup history is full of innings where one batter changed the game in the space of a few overs. As the format continues to push scoring rates higher, this current top five offers a strong picture of how quickly things can move when a set batter stays aggressive all the way through.
