SS, you serious? Sachin started opening the innings only in his 70th innings and he got his 1st 100 in his 79th inns.
He got his 13th 100 in 181st inns hence he is not in the above list. If you take from the time he started opening then 13 100s in 112 innings :notworthy:.
And the 13th 100 is the first 100 he got in 1998 which was his golden year with 9 100s. By the end of 1998 he had 21 100s in 207 innings (138 inns since he started opening) :notworthy: :Beat That:.
IIRC, before 1998 Mark Va, Lara, Anwar and Sachin all had ~12-13 hundreds and there was some tough competition. But by the end of 1998 that particular record turned out to be a no contest :).
