Who did 'Wisden' (sporting almanack) claim the greatest phenomenon in the history of all ball games?

Sir Donald George Bradman (27 August 1908 – 25 February 2001) often referred to as "The Don", was an Australian international cricketer, widely acknowledged as the greatest batsman of all time. Bradman's career Test batting average of 99.94 has been cited as the greatest achievement by any sportsman in any major sport.

'Wisden' (Cricketers' Almanack or "the Bible of Cricket") hailed Bradman as, "the greatest phenomenon in the history of cricket, indeed in the history of all ball games". Statistician Charles Davis analysed the statistics for several prominent sportsmen by comparing the number of standard deviations that they stand above the mean for their sport.

The statistics show that "no other athlete dominates an international sport to the extent that Bradman does cricket". In order to post a similarly dominant career statistic as Bradman, a baseball batter would need a career batting average of .392, while a basketball player would need to score an average of 43.0 points per game. The respective records are .366 and 30.1.
