Chance Bye, the nominal favourite for the $250,000 Racing Rewards Inglis Classic (1200m) at Rosehill next weekend, completed her final workout with a rousing run from the 1000m mark and impressed the large crowd who stayed in the stands after race three.

With big-race rider Kathy O'Hara in the saddle, Chance Bye began from a cantering start at the 1200m before quickening up in the straight.

She was timed to run her final 600m in a sizzling 33.59sec.

"Just sensational," Tubman said after the workout.

"That was just her fifth gallop in her life and she did it on her ear in a canter.

"If they can't run 1min7.5sec in the Slipper, they just can't beat her.

"Now we just have to hope that nothing goes wrong along the way."

Earlier in the afternoon, two potential rivals next Saturday showed their wares in the opening Australia Wide Security 2YO Maiden (900m).

Decision Time, trained by Clarry Conners and Boomshakalaka, from the stable of son Marc, finished first and third respectively and may well force their way into the field for the sales graduates' race.

Decision Time, in particular, looked more than useful when he lowered the course record over the little-used distance, scooting away from the well-backed favourite, Excentrique.

The gelding, which had looked by far the best trialist of the unraced brigade, was always cruising on the outside of the favourite and impressed jockey Dale Spriggs.

"He's not quite at his best yet but I like him a lot and I reckon he will end up as a decent horse," he said.

Decision Time, a cleverly named son of first-season stallion Foreplay, ran the journey in 51.79sec, which was 0.11 faster than Remarkable Girl ran in November last year.

Spriggs went on to make it an early double when he partnered the Bart Cummings-trained Breccia to victory in the Stockland Maiden (2000m).

Early plans went out of the window when the favourite began well and started to pull and reef in front with no horse keen to set the pace.

"If they wanted to walk then I was happy to walk along a bit faster in front where she was happy," Spriggs said.

His mount made all the running and shrugged off the challenges of Wild Orange and Testagame to score with ease by nearly two lengths.
