This is a dynamic link. D Elgar is the latest addition to this list in the Test starting on 24/01/2018.
The very first “carry-through” was by SA’s AB Tancred was 26* out of 47 in the Test starting on 25/03/1889. This remains a record for the lowest such score, though there are a few more under 50. The highest was recorded about a month ago, when AN Cook made 244* out of 491 in the Test starting on 26/12/2017. There are a few other double centuries, one of which is listed below.
Anyway, Elgar was only the 5th opener to carry his bat through an innings against India.
1) Nazar Mohammed, 124*/331 at Lucknow in match starting on 23/10/1952. Pakistan won by 10 wickets, though India won the series 2-1. This was Pakistan’s first Test series. See note in 3) below.
2) WM Lawry (Australia’s captain), 49*/107 at Delhi, starting 28/11/1969. India won this Test by 7 wickets, though Australia won the series 3-1. Lawry also carried his bat through an innings in an Ashes Test in 1971, which Australia lost.
3) Mudassar Nazar, 152*/323 at Lahore, starting 23/01/1983. Drawn, while Pakistan won the series 3-0. This is the only instance in all Tests where a father and son have both carried their bats through an innings.
4) Saeed Anwar, 188*/316 at Kolkata, starting 16/02/1999. Pakistan won by 46 runs. This was part of the Asian Test Championship, which was finally won by Pakistan.
5) D Elgar, 86*/177 at Johannesburg, starting 24/01/2018. India won by 63 runs, though SA won the series 2-1. Elgar had done this earlier against England in 2015, in a match which SA lost.
