Gerald Mason was the youngest of seven lacrosse-playing brothers, who all played for England at one time or another. Gerald started playing for Stockport at the age of 15 in 1892, and worked his way through the ranks to the senior team, and eventually became club captain. He started as a home and wing attack, and went on to win representative honours for Cheshire, the North, England and of course, Great Britain at the 1908 Olympics. Playing in defence as a point in the latter part of his career, Mason helped Cheshire win their first County Championship in 1909. Two years earlier, Mason had the honour of captaining Stockport against the touring Canadian champions, Ottawa Capitals, in the last match of their UK tour. The Canadians had a 100% record going into the match, but that ended when Gerald and his team held on for a memorable draw.
