She was runner-up to Vera Selby in the 1976 Women's World Open snooker championship.

Hazeldene won three national amateur titles in snooker and one in billiards between 1951 and 1971.

She came out of retirement from playing to participate in the 1976 Women's World Open snooker championship, having to win through a qualifying competition in Leeds to join the main draw.

She won on the black in the deciding frame against Lettie Haywood in the quarter-final, then produced another surprise by beating Maureen Baynton 3–0 in the semi-final.

Selby then played consistently, avoiding risks, to take the concluding two frames.
