In the list of 50 fastest Test centuries ever, there are only 15 of them which were scored before the year 2000. The game has picked up speed and batsmen nowadays score at a pace much higher than what the batsmen of earlier generations used to score. This has resulted in such a difference in the instances on the list.
The effect of T20 cricket can be seen in the ODI and Test formats as well. While this has resulted in high scoring matches, test matches last for about four days on an average and the percentage of drawn tests has been reduced.
With the ever-increasing pace of the game, more number of faster centuries will enter this list in the near future.
The quick centuries that have been scored even when the conditions didn’t force them, do not impress the purists, but can be a catalyst to attract people’s interest in the format. With the longer format being endangered, this can prove to be on the advantageous side for Test cricket.
