Merthyr Tydfil, Glamorgan born outside left Dai Lewis began his football career with Gellifaelog Amateurs in 1929 and joined Second Division Swansea Town in September 1930, making his Football League debut at Burnley the next month. He was a near ever present in Swansea’s 1931-32 campaign and such was his form that he came to the attention of the Wales selectors, making his international debut in a thumping 5-2 win over Scotland at Tynecastle in October 1932, and playing his second and final match for his country in a 0-0 draw with England at The Racecourse Ground, Wrexham the next month as Wales won the 1932-33 British Home Championship.
However his career with The Swans dipped from 1932, his opportunities in the first team were more limited and in his best season, 1935-36, he managed only 20 appearances, before he joined Bury in May 1936 after 5 goals in 113 appearances for The Swans. He managed just 8 appearances for The Shakers before joining Crystal Palace in October 1937, but he soon moved back to the West Country to join Bristol Rovers the same season. However he didn’t manage to get into the first team at either club, and joined non league Bath City where his career was ended by the outbreak of the Second World War.
