We have a rapidly growing Junior section. Reborn in September 2017, we entered an Under 9s and Under 11s team in the SWWGL from December 2017. Continually expanding, we are aiming to increase our number of sides for the 2018/2019 season to cover all age groups from Under 8s to Under 13s. New players are always welcome. We train on Wednesday evenings 6-7pm at Morgan Jones Park.
