We see that the longest lived player was John Manners of England (1914-2020) or 105+
From India there are centenarians in DB Deodhar (1892-1992, 101+) and Vasant Raiji (1920-2020, 100+).
As of today the only living first-class cricketer over 100 is Alan Burgess of New Zealand (1920-, 100+).
For a short period Vasant Raiji was the oldest living first-class cricketer (from Manners’s death on March 7, 2020 to his own demise on June 13 of the same year). He also wrote a number of cricket-related books.
The only Test player here is South Africa’s Norman Gordon (1911-2014, 103+). He played all his Tests in the SA-Eng series of 1938-39, including the Timeless Test at Durban.
