Hope you have seen the previous post:
Finally, we look at centuries in the fourth innings:

It is clearly more difficult to make a century in the fourth innings than the other innings. The most centuries here is by Younis Khan (5), while 4 others have scored 4 each (GC Smith, RR Sarwan, RT Ponting and SM Gavaskar).
Among current players there are KS Williamson (3), AK Markram, BA Stokes and several others with 2.
Among Indian players, there are Gavaskar (4) and Tendulkar (3).
Those who loved the fourth innings:
W Watson (Eng) made both his centuries in the fourth innings.
No one else has scored 2 or more centuries in the fourth innings and none in other innings.
The next best is 2 out of 4 by JB Stollmeyer.
Those who hated the fourth innings:
There is a long list of prominent batsmen who scored many centuries but none in the fourth innings.
This is headed by SR Waugh (Aus) with 37 centuries. Next are SPD Smith (Aus) with 32, M Yousuf (Pak) with 24, JE Root and V Sehwag with 23.
It is just possible that Smith and Root will score a century in the fourth innings in the future. Or Smith may cross Waugh’s record of 37.
