Born at Harrow, Bosworth-Smith was educated at Harrow School, before attending Magdalen College, Oxford. While attending Oxford, Bosworth-Smith made his debut in first-class cricket for Oxford University in 1895, playing once for the university that year against the Marylebone Cricket Club (MCC).

He played two first-class matches while in India for the Europeans cricket team in the Bombay Presidency against the Parsees in August and September 1900. Bosworth-Smith had returned home to England by 1901, where he made two further first-class appearances for the MCC at Lord's. Returning to India, his final appearance in first-class cricket came for the Gentlemen of India against a touring Oxford University Authentics team in 1903. He would later play for Dorset in a Minor Counties Championship match in 1909.
