Ralph Clark was born at Pontypool, ON, but moved to Peterborough at age seven and in his early years was a standout baseball player.
In 1929, he was a member of the Ontario champion Peterborough bantam team. A year later, he moved up to juvenile and was again on a provincial winning team.
It was curling, however, that gained him lasting sports prominence, starting with a 1932 rink, which he skipped to the Ontario Junior Tankard win. His 1949 rink was runner-up in the British Consols competition but it was his 1952 rank that earned great glory for its members and the city. That rink won the British Consols Trophy, top award in Ontario, and represented Ontario in the Canadian championships where they had a respectable 6-4 won-lost record. This is the first city rink to win an Ontario title.
Clark was skip of one of the 1953 rinks that won the Burden Trophy, and in 1955 he skipped one of the rinks in a double rink competition to win the Ontario Silver Tankard.
