Craig Carmody is almost resigned to waiting another week before giving promising sprinter Worldly Impact a chance to prove himself on a bigger stage.

The Randwick trainer has Worldly Impact entered for the main sprint race on the Kensington track on Saturday but with a field size kept to 12 runners, the four-year-old is borderline at best to get a start.

"We'll just have to see if everybody accepts. If they do we will be flat out getting in," Carmody said.

"I just thought it was worthwhile throwing a nomination in to have a look and be happy enough to accept to see how we go."

Helped by a breakneck tempo, Worldly Impact was one of the most impressive Melbourne Cup day winners at Randwick.

The merit of the win confirmed to Carmody, a former leading jockey who rides his team of racehorses in trackwork, that Worldly Impact is gradually learning his racing craft.

"He was always a bit ahead of himself, he didn't quite know how to control his energy levels," Carmody said.

"It's taken a while to get him thinking the right way.

"He's settled nicely now and he uses himself much better. He's a big strong horse with a decent turn of foot."

Worldly Impact is 24th in the ballot order as the lowest-rated horse in Saturday's 1150-metre race.

But he could easily have the most potential after making it three wins from only his sixth start when he ran away from Limitation and Elusive Lad in fast time at Randwick.

Saturday racing returns to the Kensington track for the first time since it was reopened last month.

Already it looks like it will take over the mantle as Sydney's best wet-weather course from Canterbury.

More than 70mm of rain fell on Randwick up to Monday morning, but the all-weather Kensington track was barely affected.

So much so, it has earned widespread approval from jockeys such as Tulloch Lodge rider Tommy Berry who rates it as the best track in Australian racing.
