Ainsworth qualified as a surgeon prior to 1915. It was during World War I that he was enlisted as a surgeon in the Royal Navy in September 1915. He continued to serve in the Royal Navy following the end of the war, as he was selected to play a first-class cricket match for the Royal Navy against Cambridge University at Fenner's in 1919. In a match Cambridge University won by an innings and 84 runs, Ainsworth scored 6 runs in the Royal Navy's first-innings, before he was dismissed by Gordon Fairbairn, while in their second-innings he top scored with 71, before being dismissed by Gilbert Ashton.
He died at Elton, Lancashire on 20 February 1940.
