Surprise packet Savannah Jay Jay will be hoping to carve another fairytale chapter tomorrow night when the low-flying eight-year-old trotter zeroes in on Ballarat's trotting cup.

The John Slack Memorial Trotters Cup, at 8.40pm at Bray Raceway, is the penultimate race of the Maori's Idol Trotting Championship, in which Shaun McNaulty's Fratellino has an unassailable lead.

Savannah Jay Jay can jump to equal third with victory tomorrow night, which would add to his earlier success in November's St Arnaud Cup and, of course, last Saturday's Schweppes Australasian Trotting Championship win, which delivered trainer Stan Cameron and reinsman James Herbertson their maiden Group 1.

"I had no idea that he could run the whole journey out," Cameron told RSN 927's program One Out One Back. "I thought, if he got a bit of cover he would have been right, but right up to the end I was right up on my toes I tell you. The horse just kept on fighting and fighting and fighting to the end."

Savannah Jay Jay was priced a $2.25 chance at the TAB.com.au for the John Slack Memorial Trotters Cup, a win that would mean the world to Cameron.

"I had a fair bit to do with John years ago," he said. "John used to always get a ride down to the start on the side of the cart, he used to always say 'you need to do this, you need to do that'. I picked up a fair few pointers off him over the years. He was a great bloke."
