Trained by Correy Grenfell at Mt Wallace, Tiggerlong Tonk "shot the lights out" setting a race record in Thursday night's group 3 Shootout, 515m, at Sandown.

He was the outsider in the $25,000 winner-take-all four-dog match race.

"We thought we had him cherry ripe and that all he had to do was jump," Grenfell said.

"To do it now so close to the Melbourne Cup, we couldn't ask for more."

Tiggerlong Tonk gave Grenfell his second Shootout, having scored with Orson Allen in 2018, and became the 10th winner from box five since the race's inception in 1998.

Tiggerlong Tonk now has the career record of 31 wins and 16 minor placings from 59 starts, for $328,670 in stakes.

All but one of his wins have been over middle distances, from 424m to 569m.

Shootout night was the third of five nights of racing across The Meadows and Sandown Park which form the new festival of racing, in which almost $2 million in prizemoney is being distributed.

Tiggerlong Tonk will now be set for the heats of the Melbourne Cup on Friday.

He rated a $17 chance to claim what is widely regarded as the world's greatest greyhound race.

The $630,000 Melbourne Cup Final will be run at Sandown on Friday, November 27. Ten Melbourne Cup preludes were also run at Sandown on Thursday.
