before his last innings in test career sir donald bradman had said that he will give a surprise to everyone, and he did give a surprise to every one......What was that surprise?

Bradman needed just 4 runs in his final innings to finish with a Test batting average of exactly 100. Instead, he was dismissed for 0 (a duck), ending his career with an average of 99.94 - arguably cricket's most famous near-miss. A double or triple hundred would have been celebrated, but a duck was the shocking 'surprise' he gave cricket fans.
