What was Don Bradman's test cricket average as he walked out onto Kennington Oval in August 1948, for his last-ever test innings?

Bradman scored 6996 runs in 70 completed innings for an average of 99.94. As he walked out to bat for his last innings, his average was 101.39 (6996/69) but famously did not add to his score being bowled second ball, so his average plummeted to the aforementioned 99.94. He needed to score only 4 runs to end up with a career average of over 100, a feat never likely to be repeated.

In support of the above answer, Sir Donald "The Don" Bradman would certainly qualify as one of, if not *the*, greatest sportsman of the 20th century. Opposing teams had to resort to some extreme and still controversial tactics to counter his phenomenal batting skills.

To provide some sort of context of his achievements within the world of sport:

As per the statistics 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 over their career , while a ice hockey player should score 2.8 goals per game.The respective records are .366 and 30.1 and 1.93.
