5 biggest upsets by Associate nations in ODIs

#1 Zimbabwe vs Australia (1983)

Duncan Fletcher's all-round heroics propelled Zimbabwe to victory on ODI debut

Zimbabwe was elected as a Full Member on July 1992 and became the ninth Test playing country. The African nation's formative years began in 1981 when they gained Associate status from the ICC. After clinching the 1982 ICC Trophy, they earned the right to participate in the 1983 World Cup.

Playing in their first ever ODI, Zimbabwe produced a performance for the ages by slaying a strong Australian team at Trent Bridge. Duncan Fletcher, who would later go on to coach England and India, led from the front with a splendid all-round effort. The skipper's gritty 84-ball 69 carried the side to a competitive total.

Chasing 240 from 60 overs, Kepler Wessels began to set the platform from the top order. However, Fletcher derailed their plans with back to back wickets. Wicket-keeper batsman Rod Marsh's attacking half-century could not prevent Australia from slipping to an ignominious defeat.

Brief Scores: Zimbabwe - 239/6 from 60 overs (Duncan Fletcher 69*, Iain Butchart 34*, Graham Yallop 2/28, Dennis Lillee 2/47); Australia - 226/7 from 60 overs (Kepler Wessels 76, Rod Marsh 50*, Duncan Fletcher 4/42)

Result: Zimbabwe won by 13 runs
