Spurway played cricket for the Somerset Stragglers while at university. He won a place in the Somerset county team as a wicketkeeper-batsman in three games of first-class cricket in July 1929, but yielded his place in the team to his brother, Francis, who had played irregularly for Somerset between 1920 and 1929: both were substitutes for Somerset's regular wicketkeeper, Wally Luckes, who was ill for much of the season. Michael Spurway played against Leicestershire at Taunton, and against Sussex and Derbyshire at Bath. Free-hitting, he was known as "Slogger Spurway". His father and an uncle Robert also played cricket for Somerset in the late 19th century, and a cousin, Robert played for Glamorgan in 1943.
