After losing his way in the spring, talented colt Sidestep has recaptured his form in Sydney and is in line for an even bigger prize than the Royal Sovereign Stakes.

His victory in Saturday's Group Two 1200-metre race at Randwick on Saturday has set him up for a tilt at the All Aged Stakes on the final day of the autumn carnival.

Runner-up in the 2013 Golden Slipper, Sidestep was unplaced in five starts as an early three-year-old but this time around he has won two of his three starts and finished a close second in the other.

He made hard work of the Royal Sovereign after leaving the gates slowly as New Zealand filly Bounding, the $4 favourite, took up the running.

Kerrin McEvoy got him into the clear in the straight and Sidestep ($4.60) gave chase and wore down Bounding to win by a short neck with Gosford Guineas winner In Cahoots ($26) another 2-1/2 lengths third.

"It wasn't in the script to be there at all," trainer Peter Snowden said.

"We wanted to be positive and have him up on the speed from the good draw today but he was slow out and everything went pear shaped.

"Kerrin bided his time and rode for luck and got it.

"He has been getting back to his two-year-old form.

"The All Aged Stakes is a race that is tailor made for him."

The Group One All Aged (1400m) joins the Champagne Stakes as Group One features next Saturday.

Bounding had to work to get across from the outside barrier and the early effort told in the final few strides.

"I didn't really want to work as hard as I did from the draw," jockey Mark Du Plessis said.
