Wass played one first-class match for Derbyshire against Glamorgan during the 1929 season, in which he played one innings to make 9 runs. Though he did not appear again for Derbyshire, he became a leading light in the days of pre-war Scottish cricket, making his first appearances during 1935, and further appearances against teams assembled by Sir Julien Cahn between 1935 and 1937. He appeared for Scotland eight times in total: twice against the South Africans, once against the Australians and five times against Sir Julien Cahn's XI. These games did not have first-class status. He was a right-handed batsman.
