Recent 100-1 debut winner Astro Castro is the horse that keeps paying out.

And this time it is the horse’s trainer Alan Hunter that has had a big collect thanks to the generosity of one punter who cleaned up on the massive $131,000 quaddie in which Hunter’s horse was the last-leg winner.

Daniel Gangi has become something of a social media sensation – at least in racing circles – after video footage of him cheering home the quaddie went viral during the week; Gangi stood Darren Weir’s Royal Rapture out on its own in the third leg and covered it with three fields – rank outsider Astro Castro delivered Gangi a near $70,000 result.

“It was an amazing day, I’d actually done it before at Geelong so lightning can strike twice. I wanted to thank Alan somehow so I had a think about a special way to do it,” Gangi said.

As well as being a handy punter, Gangi is horse owner and has a share in Rosemont Stud’s freshman stallion Nostradamus. As a part of that share, Gangi is entitled to send two mares to the son of Medaglia D’Oro – he already had booked one mare but decided to give the second one to Hunter as something of a “sling”.

And in the perfect response to the offer, Hunter and Astro Castro’s breeders have decided to send Astro Castro’s dam Myxaar to the stallion.

“It seemed like the perfect way to thank him. Astro Castro is a horse that I will always follow and always remember and now he will have a little brother or sister by my stallion Nostradamus which is even more special. Hopefully the colt or filly can go on to win at Flemington one day as well,” said Gangi.

Rosemont proprietor Anthony Mithen said that the offer was one of the best “slings” he had ever seen in his time in racing, and was thrilled that Hunter accepted the offer.

“He (Hunter) was taken aback by Daniel’s offer but was happy to accept. He and the mare’s owners were pretty thrilled to be able to send Myxaar to a stallion as exciting as Nostradamus,” Mithen said.

“All great racehorses have a great story behind them, hopefully one day we are looking back and talking about this as the back story to a champion.”
