After winning at the Murrumbidgee Turf Club on Town Plate Day early this month, the eight-year-old is aiming for back-to-back victories in heats of the Wagga Stayers Series in the $22,000 Byrnes Trailers Benchmark 66 Handicap (2000m).

Widdison said this is the first time he's had the old stager right from the beginning of a preparation and is hoping to see a repeat performance, despite an additional two kilograms in weight.

"He came through the run great. It took me two-and-a-half years to get a win with him so it seems strange that he's a big chance to go two in a row," Widdison said.

"He's a good old horse, just the weight and class can catch up with him sometimes. But this looks a nice race for him.

"He only has to replicate his run from last time I think. He's up to 61kg but he carried the 59 and won it well."

Baby Jack is one of only four horses in Sunday's entire program to be coming off a last-start win.

Jake Duffy takes over from Nikita Beriman, who will be riding two at Flemington for Widdison on Saturday, including Wagga Gold Cup third placegetter, Willi Willi which is in the $135,000 Vo Rogue Hall of Fame Trophy over the Gold Cup distance of 2000m.

"I'm pretty happy with him. I think he's sort of bounced off that run and it's brought him on again," Widdison said.

"I think he's drawn to get a lovely run, he likes Flemington, and I don't think the race is any harder than the Wagga Cup."

Two of Willi Willi's five career wins have been at Flemington.

Widdison has three other runners in Wagga's seven race card on Sunday, including Rewards Card and This Skilled Cat in the first two races, but Tyson's Return has also accepted at Wodonga on Saturday and appears unlikely to head to the MTC.
