Richard and Chantelle Jolly have their sights on a Racing Rewards SA double at Murray Bridge on Saturday.

Exciting three-year-old Karacasu will be trying to regain winning form after a brave run behind two exciting prospects in the Listed Creswick Stakes in Melbourne while Klabel will be hoping to take an impressive eight length trial win to his race day debut.

Both horses are raced by one of the stable biggest supporters Neville Morgan.

Klabel is a $120,000 purchase from last year's Karaka Yearling Sale in New Zealand by Vadamoss who Jolly said he had progressed nicely for his debut.

"We looked at this race about a month ago and I wasn't quite sure he'd be ready,'' Jolly said.

"But he's come along well and at the trials the other day I said to Jake (Toeroek) to shake him up and he really put a space on them when he was asked for an effort,'' he said.

Karacasu has come through his Melbourne run perfectly according to Jolly and is marked an odds-on favourite in a race where he was ideally weighted.

"I think if it was handicap conditions, he'd have about 63kg, so he gets in pretty well on the weekend,'' Jolly said.

"He's come through Melbourne well, it proved he's up to that better class,'' he said.

The $102,250 late season features for Racing Rewards SA horses will mean more than $2.5m in Racing Rewards SA bonuses have been handed out in season 2021-22.

The Jolly stable are poised for their first South Australian and Adelaide Trainer's Premierships and have a host of good chances on the bumper 10-race card.

"Yuri Royale was a winner first-up last time in, I think Alleboom is close to winning and drops slightly in class and Perfect Illusion was a bit unlucky the other day and draws a nice barrier,'' Jolly said.
