Gai Waterhouse to cop stewards' wrath after Dunaden and Tres Blue caught up in treatment controversy GAI Waterhouse won her first Melbourne Cup with Fiorente yesterday but faces a stewards' inquiry this week regarding her other Cup runner, Tres Blue. Waterhouse admitted one of her staff had treated Tres Blue at 5.50am yesterday with Flamazine, an antibiotic cream, for "greasy heel." A new Rule of Racing states no galloper can be treated on race day, and a minimum six-month disqualification applies. Stewards allowed Tres Blue to run in the Cup. He added stewards agreed this was at the "minor end of the scale when it comes to ¬race-day treatment." It is unlikely Waterhouse would be disqualified. She initially told stewards she had no knowledge of the treatment and asked for an adjournment of the inquiry to speak to her stable representative, Ryan Prendergast, who was looking after Tres Blue. She returned to say Prendergast had made "a very ¬honest mistake." He put it on by mistake. There is nothing swabable in it," Waterhouse said. Bailey explained there was a clear difference between yesterday's treatments (French champion Dunaden also was treated) and the recent Happy Trails inquiry. Happy Trails was scratched and trainer Paul Beshara later disqualified for six months. "With these horses we know what they (substances) are and they are not prohibited substances," Bailey said. Frenchman Mikel Delzangles, trainer of Dunaden, is also facing an inquiry. A security guard told stewards Dunaden had been treated with a cream. Delzangles explained it was not a prohibited substance but an ulcer treatment. I'm very sorry. It is a big mistake. Matthew (stable foreman) didn't know he was doing," he said. We use it every day. We consider it like food. James Williams, who defended Beshara at the Racing Appeals and Disciplinary Board hearing, slammed the stewards' decision to let Dunaden and Tres Blue run. Williams, a former Racing Victoria steward, vented his dismay on Twitter. "If ANY horse is found to have been treated on race day then the trainer should receive six months," Williams tweeted, with "#mandatory sentences" and "#no room to move."
