#2 Michael Slater (Australia) - ODIs
A modern batsman in the 90's era, Slater had a vicious front foot pull shot and a flamboyant style of batting that you would normally associate with an ODI player. Despite his issues in the 90s, the opening batsman had a successful Test career racking up 5312 runs in 74 Tests at an average of 42.83.
Expected to be a huge success in ODIs, Slater rarely managed to replicate his Test success in the shorter format. In 42 ODIs, Slater scored just 987 runs with zero hundred and nine half-centuries. He could not even get to nineties in ODIs with a highest score of 73.
But Australia showed poor judgement in thinking he would be a hit in One Day cricket. His List A stats reveal that Slater had never been a success in shorter formats. He averaged just 26.52 in List A cricket in 135 games and scored just two hundreds. His Test career too faded off after the emergence of Matthew Hayden and Justin Langer.
