Centuries on Test debut are well documented:
Here we look at those who scored one or more scores of 50 to 99 on debut.
Some points of note:
Dilawar Hussain and SM Gavaskar scored fifties in each innings on debut.
The Yuvaraj of Patiala (father of current Punjab CM Amarinder Singh) was playing in his only Test.
A few of these players went on to successful careers, notably Amar Singh, Mankad, Phadkar, Nadkarni, Gavaskar, Dravid, Laxman and Pujara.
But here are quite a few who ended their careers with 5 or less Tests and/or are forgotten to most cricket fans. These include the 2-Test players Kanitkar (senior), P Roy (junior), Rajput and Badrinath.
The jury is still out on Pandya. Let us hope that Vihari and MA Agarwal do better.
It is also worthwhile to look at all such Test players since 2014:
Note fifties in both innings by MDKJ Perera and Fakhar Zaman.
The most successful among these include MDK Perera, MDKJ Perera, JO Holder, Dickwella, Buttler, Dowrich, Handscomb, Pandya, Markram, Roshan Silva, Imam and Finch. And there are several others who are unlikely to play Tests again.
