At just 19, Flower was part of the 1990 ICC tournament where the winner would qualify for the World Cup. Zimbabwe would go on to win the competition with Grant Flower scoring heavily in the early games. Had they not won the competition it is likely that Zimbabwe would not have made their rise to Test cricket, at least not until much later. Grant Flower missed out on the 1992 World Cup due to injury. In 1993 Grant spent a season in England with Widnes Cricket Club in the Manchester and District Cricket Association. He also spent a season at Wallasey Cricket Club of the Liverpool Cricket Competition in 1995.
