I Am Invincible had the most impressive winner of the day at Sha Tin on Sunday when exciting prospect Bad Boy bolted away to win as he pleased. Trained by John Moore and ridden by Zav Purton, Bad Boy showed brilliant speed to win the Class Three sprint by more than three lengths as favourite. He clocked a brisk 55.66 seconds for the 1000 metres ins a sizzling display. Bad Boy was a $30,000 Inglis Classic purchase from the Sefton Park Thoroughbreds draft for Kennewell Racing and after winning two of his first three starts in explosive fashion for Lloyd Kennewell in Adelaide was on-sold to Hong Kong. “He only had the three runs in Australia and now four here so he needs more experience, but he looks a very nice horse for next season on that. I probably won’t run him again until then. There’s only a 1,200m left for him at Happy Valley this season after he goes up in the ratings for this one, so that’s probably it,” Moore said. Zac Purton was impressed with the win. “When they surged at me, I had to press the button and let him go and the response was immediate,” he said. “Maybe he did like the soft ground with that shuffly sort of action he has but he just dropped them instantly. That was very cosy.” Bad Boy is one of two winners from Pins mare Andneedles, who comes from the family of Group I stars Grand Armee, Anamato, Drum, Dealer Principal, Wylie Hall and Absolute Champion.
