Duncan Spencer is a former Australian cricketer who played for Western Australia and Sussex in county cricket. He was known for his fast bowling skills, but his career was cut short due to a doping scandal. In 2006, he made a comeback to the game after being banned for 18 months for taking steroids. However, he struggled to regain his form and eventually retired from professional cricket. Despite this, Spencer's achievements in the sport are still remembered fondly by cricket fans.
