During 1937, Basketball had increased in popularity, not only with senior players, but also with the younger members. Junior games were played extensively and in 1938 ABBA organised on similar lines to the Senior Championships a National Junior Championship of England and Wales. Plaistow YMCA presented the ABBA with a Challenge Cup. On 9 April 1938 the first Junior Championship Final was held in Birmingham between Ton Pentre (Rhondda Valley) Boys' Club and London Polytechnic with the Welsh Club winning the first tournament.
