Waterhouse cops $2000 Cup fine over Tres Blue raceday treatment Trainer Gai Waterhouse comes out of the stewards room after the Tres Blue inquiry on Melbourne Cup day. TRAINER Gai Waterhouse has been fined $2000 for the raceday treatment of her Melbourne Cup runner Tres Blue. Waterhouse, who wasn't in Melbourne for the inquiry but was represented by her lawyers, argued she was at no time aware that Tres Blue had been treated with a cream for a condition known as greasy heal, after a stable employee had applied the treatment. The Racing Appeals and Disciplinary Board agreed the infringement was at the lower end of the scale and agreed to a lesser charge of negligence for the trainer. RAD board chairman Russell Lewis fined Waterhouse $2000, for which she has until November 30 to pay. It was a minor blemish on the day for Waterhouse, who celebrated her maiden Melbourne Cup win with race favourite Fiorente.
