Rockn N Rolln in fine form this preparation for Oberon trainer Watterson

And he appears to be all the better for it.

Wayne Watterson's veteran gelding has looked like a new horse this preparation since freeing up his legs, claiming two wins at Bathurst and chasing another at this Wednesday night's meeting.

Rockn N Rolln lines up as a strong contender in the Inspect Lot 559 @ Sydney APG Sale (2,260 metres) where he has the chance to lead the race out of gate two.

Watterson has been thrilled with the progress his seven-year-old has shown since he ditched the gear.

"He's going really good now. I've taken his hobbles off and since I've done that he's a new horse," he said.

"At the beginning of the year, with the smoke, I was working him a lot without being able to go to the races. I sent him to trial twice, to qualify him to be a free-legged pacer, and he came first and second at those.

"Now he's had four starts free-legging and he seems to be trying more and looks freer in his action. A lot of people have commented on how much more free he looks."

And it's not just on the track where Rockn N Rolln is showing a change.

Watterson said the Rock N Roll Heaven gelding's temperament at home has also evolved.

"You'd go to catch him sometimes to go the races and he wouldn't let you catch him," he said.

"Now he's virtually walking up to the gate to go to the track. He really is like a new horse."

Watterson would love an exact copy of Rockn N Rolln's previous run, where he led all the way out of gate two to win the Gold Crown Carnival Pace (2,260m) a fortnight ago.

Among the challengers are inside starter Imthevillagestar, who ran second at long odds last week, along with recent Menangle placegetter Lets Katchmeifucan.

The night's feature event sees Sams Express, Callmequeenbee, Maximus Red and Holy Camp Clive battle it out.

Racing on Wednesday night gets underway from 6.05pm.
