Masters plays his club hurling and football with the famous Nemo Rangers club in Cork and has enjoyed much success. He joined the senior panel in the early 2000s, however, he had to wait several years before he would make a big impact, due to the presence of stalwarts Joe Kavanagh and Colin Corkery playing in his favoured position. In 2002 Nemo reached the final of the provincial club championship. Masters came on as a substitute in that game as the club trounced Monaleen of Limerick by 4–15 to 0–6. It was Masters's first Munster Senior Club Football Championship winners' medal. In spite of contributing to this victory he played no part in Nemo's subsequent All-Ireland Senior Club Football Championship triumph on St. Patrick's Day, 2003.
