He replaced the previous scorer, Arthur Wrigley, who had been the BBC scorer from 1934 up to his death in October 1965. Frindall speculatively wrote to the BBC, pointing out that they would need a new scorer, and secured the job. After a trial period, Frindall continued to score for the BBC until his death, watching all 246 Test matches in England from June 1966 to 2008. He covered 377 Tests for the BBC in all, forming a close working relationship with John Arlott and Brian Johnston, providing continuity with later commentators such as Jonathan Agnew. Frindall's perfectionism clashed occasionally with Henry Blofeld's more effusive – but error-prone – delivery.
