The T20 season in 2007 came full bloom for Indian batsman Yuvraj Singh when a new record was created by him in a match against England.
On 19th Sep 2007, Yuvraj Singh in a group game during the first edition of the ICC World T20 slammed Stuart Broad for six sixes in a row at Kingsmead in Durban.
At the end of the 18th over, Indian team was on 171 for 3 wickets and two master players Yuvraj and MS Dhoni were playing looking to finish off the game on a higher score.
After three consecutive sixes by Singh, Broad tried switching to around the wicket for his final three balls, but the pressure had got the better of the young English bowler who was unable to find his length. Singh used this momentum to strike a further three dismissive sixes and become the first batsman to hit six 6’s in one over in a World Cup.
First one over long-on, the next over backward square leg, the third one over extra cover, then a swat over deep point to a full toss, the fifth one a hoick over deep midwicket and finally a massive hit over wide long-on.
This makes the record for “Most Runs in an over – 36 Runs “ in T20 World Cup.
Yuvraj made a record of 12-ball half-century, which to date remains the quickest fifty in T20Is. He finally finished on 58 runs in 16 balls and his innings consisting of three fours and seven sixes, making Indian team a total run tally of 218 runs for 4 wickets.
This was the first and so far remains the only instance of any batsman smashing six sixes in an over in a T20I. Herschelle Gibbs had achieved the feat in a One-Day International during the World Cup in 2007 against the Netherlands while Gary Sobers and Ravi Shastri have managed to do so in first-class cricket.
