The list makes for interesting reading in that while opening batsmen have performed the feat, it has also been accomplished by one player batting at No 9.
There are fast bowlers and spin bowlers alike and in some cases despite the heroic showing of the player concerned, it has not helped in averting defeat.
The great Jack Gregory it was who came in so late in the batting order, scored exactly 100 and then took seven for 69 as Australia romped to an innings victory over England in January 1921.
Ashwin came close in that he batted at No 8. But then there have been two others in the list who batted so low in the batting order, New Zealand's Bruce Taylor and Zimbabwe's Paul Strang. The former in fact is the only one to have performed the feat on his debut - against India at Calcutta in 1965.
Ashwin's feat at Mumbai a few days ago was only the third by an Indian in Test cricket. What enhances the value of his double is that the previous occasion was almost half a century ago.
At Port of Spain in 1962, Polly Umrigar scored 56 and 172 not out (top score in both innings) and took five wickets for 107 against the West Indies.
