1. Paul Adams
The South African unorthodox spinner Paul Adam has to be at the number 1 spot. He made his Test debut against England 1995 and left everyone speechless. Adams made a mockery of the coaching manuals and stunned everyone. It would be right to say that he was the first that invented the weirdest bowling action in Cricket.
The left-arm spinner to his credit was pretty successful in international cricket. Adams managed to play 45 Test matches in which he scalped 134 wickets with 4 five-wicket haul. It was a great sight to see him going about his business and deliver the ball. Adams proved that a bowler can play for his country even by with the weirdest bowling actions in cricket.
