Reardon remained one of snooker's top players into his 50s, setting a number of records. He became snooker's oldest World champion (in 1978, aged 45 years and 203 days), and the oldest player to win a ranking event (in 1982, aged 50 years and 14 days). His highest in competition was 146. He also worked with Ronnie O'Sullivan in a coaching role, helping him to win the 2004 World Snooker Championship. Reardon's dark widow's peak and sharp-toothed grin earned him the nickname "Dracula".
