There used to be a race traditionally for 3 years old only on Derby weekend. It used to be called Breeders produce stakes. 

Has the race been renamed?

Some of the prominent winners of this race have been future champions. I remember some owners used to take this race very seriously and used to race classic hopefuls in this race if they did want to race it in Poonawala Breeders multi million. 

I remember the famous objection in 2 champion horses in this race. Autonomy with Richard Hughes had won and Rajendra on Set Alight had taken an objection and it was upheld.
