Gai Waterhouse to face inquiry over Rockabill scratching Horseracing Under question: Champion trainer Gai Waterhouse is facing another inquiry. Trainer Gai Waterhouse and her lawyers will head to Racing NSW headquarters on Friday for another inquiry into the fitness of a horse to race after the scratching of Rockabill from the Spring Stakes at Newcastle. Stewards acted on reports the Coolmore-owned Rockabill had been lame in the lead-up to Wednesday's Group 3 race and had the colt vetted before he left the Waterhouse stable to make the trip north. Racing NSW veterinarian Craig Suann found the son of Fastnet Rock to be lame and he was immediately scratched at 10.30am on race morning. Waterhouse will be accompanied by Philip Beazley, who represented her in the More Joyous inquiry earlier in the year. She was found guilty of not reporting a condition that could affect More Joyous' performance before the All Aged Stakes and fined $5000 on that occasion. She also fined $2000 on similar charge with More Joyous leading into the Queen Of The Turf. Both those convictions are subject to appeal to be heard next week. Stewards will consider whether to charge Waterhouse under the same rule for a third time in this Rockabill inquiry. It comes only days after she was reminded about her obligations after it was revealed Aussies Loves Sport won the Ming Dynasty Quality despite a cut to gasket, which went unreported. Evidence is set to taken from Waterhouse's vet Leanne Begg in Friday's inquiry about Rockabill's condition in the days leading into the Newcastle race.
