You do have to realise there are heaps of 3yos about in the north. You only have to look at this Sunday. Fields of 8,8 and 9 accepted in the three 3yo races. Probably 7 or so will go around in each, so more than enough to justify another $100,000 of industry money.
Only four 3yo races scheduled for slot day, plus a WFA 2,000m for those who fancy a 2,000m race, and an open 1,200m for the sprinting 3yos. So only six opportunities for 3yos on the day. Should easily get 7 or 8 for each race. Probably a chance for some maidens to race for decent money as well.
