Zimbabwe Beat Australia in Cape Town - 2007 T20 World Cup Image Source : Getty Images The most exquisite maiden tournament upset in the history of the sport of cricket in the first 2007 T20 world cup was the five wicket defeat of Australia by Zimbabwe in Cape Town. Australia with their super stars such as Ricky Ponting, Matthew Hayden and Andrew Symonds were only limited to 138-9 despite the excessive favoritism. Elton Chigumbura's exceptional 3-20 in three overs dismantled Australia's vaunted batting lineup, with only Brad Hodge (35*) and Symonds (33) providing resistance. The chase of Zimbabwe represented a fearless performance with opener Brendan Taylor scoring an uninterrupted 60 in 45 balls with the help of Hamilton Masakadza (27) and Vusi Sibanda (23). Zimbabwe reached 139-5 in 19.5 overs, when they declared that the unpredictability of T20 cricket would be the norm to be used in the game forever.

England put on a 162-5 with Luke Wright (71) and Ravi Bopara (46) on the rampage after breaking a 102-run first-wicket stand. Nonetheless, both set batsmen were dismissed by Ryan ten Doeschate 2-35 which curtailed the pace of England.
