The registered racename is named in honour of the former AJC Chairman Keith Mackay. In 2014 the ATC substantially increased the prizemoney and the race was scheduled as part of the ATC Championships series and renamed the race to the Royal Randwick Stakes. In 2015 the race was once again renamed in honour of the veterinarian Percy Sykes (1920–2014), who had saved
Tulloch and had worked with famous trainers in the industry, including
T J Smith,
Bart Cummings,
Gai Waterhouse and
Jack Denham.
