John Singleton says if Gai Waterhouse's runner Fiorente wins the Melbourne Cup he'll be gracious and shake her hand Gai Waterhouse poses with Melbourne Cup Favourite Fiorente at Flemington Racecourse. IF champion trainer Gai Waterhouse brings home her first Melbourne Cup on Tuesday, racing rival John Singleton knows exactly what he'll do: He'll shake her hand. But he can't say the same for Waterhouse. "Bloody oath I would," said Singleton, asked if he would congratulate her. I've got no idea what Gai would do because she still has some legal stuff going. But I only wish her well, I really do. If her cup favourite Fiorente races to victory, it would crown Waterhouse's stellar career. But Singleton hopes to turn the tables with his runner Dear Demi, bred at his Central Coast property. He stands to win up to $10 million in prizemoney and bets if his horse wins.

That Waterhouse and Singleton have opposing runners in the Cup provides an intriguing postscript to the ugly public feud that erupted at Randwick in April when Singleton accused Waterhouse of concealing an injury to his champion mare More Joyous. The spat that turned into a bitter legal stoush featuring a colourful cast including brothel owner Eddie Hayson, NRL star Andrew Johns, bookie Tom Waterhouse and ex-jockey Allan Robinson, still lingers. Waterhouse recently mounted a second appeal against the $7000 she was fined for twice failing to accurately report More Joyous's condition. But Singleton said it is the quest to win the Melbourne Cup that excites him, not the prospect of beating his once close friend of 35 years and his former long-time trainer. "I'm over all that well and truly," said Singleton, who believes his falling out with Waterhouse could have been avoided if he had removed all his horses from her stable after she chose an outside barrier for More Joyous in the 2012 Cox Plate against his wishes. I took half my horses off her after she chose the No. 11 barrier in the Cox Plate," said Singleton. I should have taken them all off her then and it wouldn't have turned out the way it did.

Singleton was fined $15,000 after pleading guilty to two counts of improper conduct, partly because of unsubstantiated allegations that Tom Waterhouse had received inside information about More Joyous. But Singleton maintains he did not sack Waterhouse on television or insult her in the manner which has been reported. "I sacked her upstairs (after the race)," he said. I told her not to come near me and she did. I didn't say anything like what some of those enhanced recordings suggested I did. But that's over and done with. While the high profile pair have not mended any fences, Singleton will bear no grudges when he travels to Flemington on Tuesday. I wish Gai well, I wish Fiorente's rider Damien Oliver well, they're legends. But hopefully Dear Demi becomes a legend on Tuesday by beating them all.
