Dual Group 1 finalist Tiggerlong Tonk has cemented his rating as one of sport’s finest sprinting talents.

Tiggerlong Tonk recently won the G2 Horsham Cup (485m), and shortly after claimed the Ron Nestor Memorial (450m) on G2 Shepparton Cup night.

He was also a finalist in last year’s G1 Hobart Thousand (5th) and this year’s G1 Silver Chief (3rd).

But his trainer, Correy Grenfell, says “the best is yet to come” for the 25-month-old speed machine.

“He’s still got improvement in him… And that will come with age and experience,” Grenfell said.

Tiggerlong Tonk (Feb ’18 Dyna Double One x Tiggerlong Dot) has won 16 races from 29 starts, with stakes totalling $153,055. And he’s riding the crest of a wave, having won five of his past six starts.

“He’s a more accomplished sprinter and is definitely getting stronger… His run-home times are improving,” Grenfell said. “But he needs to get out of the boxes better… He’s pretty excitable in the boxes, but hopefully he’ll learn to settle down.”

Tiggerlong Tonk (Box 5) – Race 8, 9.29pm – will contest a Free For All (515m) at Sandown tonight.

And it promises to be a crackerjack affair, with only one length separating seven of the eight runners.

He’s pitted against stars such as G1 Australian Cup champ Fernando’s Riot (Box 3), G1 Temlee third place-getter Slingshot Hammer (Box 8) and recent G2 Shepparton Cup runner-up Snags McKenzie (Box 1).
