Observer stifles the betting apps market for the Victoria Derby (2500m) this afternoon at Flemington.
The Ciaron Maher trained three year old was arrogant in the Drummond Golf Vase last Saturday and is racing like 2500m will be no issue. He is a clear market leader at $2.25.
Runner up in the Vase, Providence, is at $6 on the second line of betting, with Options at $10. Autumn Mystery is at $11 and is being kept safe with most wagering sites.
