Trainer Robyn Goodwin has always considered Shocked almost as talented as that greyhound's Group 1 winning sister and kennelmate Velocity Liberty (pictured) and he looks drawn to fulfil his potential by winning at Wentworth Park on Saturday night.

Shocked is ideally positioned in box one in the 520m Track Loyalty Member Stakes, a 520m fifth grade, and while his Wentworth Park record stands at a single win and four placings from nine appearances, Goodwin's greyhound is better than that tally suggests.

At his most recent Wentworth Park outing on December 22 Shocked was sent out a $3 favourite from box two but after jumping in front was headed off by brilliant front-runner Esther's Bella.

Shocked was still in a prominent position entering the back straight when Federal Brae pushed up underneath him, allowing Esther's Bella to skip away with a winning break.

After being relegated to third spot Shocked came again to beat all but Esther's Bella while Federal Brae faded to finish third.

Federal Brae proved the form by scoring a comfortable win at Wentworth Park on Wednesday night and from his rails alley on Saturday, Shocked should lead throughout.

Coming back in distance after a pair of 603m wins at Gosford won't be a problem for Gizza Malarkey when the in-form sprinter contests Saturday's third heat of the 520m Ladbrokes Monthly Medal.

That's the opinion of trainer George Borg who said: "Gizza Malarkey beat a top class field over a middle distance at Gosford last Sunday but pulled up a treat and is feeling really well, jumping out of his skin.

"Reverting to 520m won't worry him as he is well drawn in box two on Saturday, he needs to be near the rails.

"Gizza Malarkey was beaten in his first few Wenty starts because he got checked after drawing a succession of wide boxes.

"He is a very honest dog, a good chaser, and I expect him to win on Saturday providing Blabba Mouth, who has box four, doesn't beat him to the first corner.

"I have a healthy respect for Blabba Mouth, he is a good dog and is racing well, but he has box four so Gizza Malarkey has the box draw advantage.''

Diamond Heart has been runner-up in two from four Wentworth Park starts but gets her chance to break through after drawing near the rails in box two in Saturday's opening event, the 520m Ladbrokes Odds Boost Stakes.

Diamond Heart was badly hampered attempting to cross to the inside fence after drawing box five at Wentworth Park last Saturday night and did well to finish strongly and beat all but Aston Marquee, going under by only a length.

Daniel Gatt, foreman for leading trainer Mark Gatt, said: "Diamond Heart is no world beater but she is a good 'bread and butter' dog and is certainly well boxed on Saturday.

"She will be hard to beat if she can get to the lead in the early stages as the only reason she hasn't yet won at Wenty is because she has not been able to hit the front at the first turn.''

Trainer Simon Rhodes has enjoyed his most successful year and could end 2018 by landing the quinella with Dyna Aviator and Lila Bale in Saturday night's 520m Ladbrokes Daily Video Stakes.

Dyna Aviator missed the jump when second to Sunburnt Opal at Wentworth Park on Wednesday and made the pace when third to Hit Record and Veloce Nero there in a tougher race four nights earlier.

Lila Bale was having her first start for Rhodes when she led to the catching pen before finishing fourth to Dual Keroma in a top grade event at Wentworth Park on Wednesday night and drops to fifth class on Saturday.

"In her first two trials since joining my kennels Lila Bale was disappointing but her third trial was good so she is improving all the time,'' Rhodes said.
