Buck's Future produced a slashing trial for the up-coming Group 1 Ladbrokes Paws Of Thunder with a stunning 29.70s performance at Wentworth Park on Saturday night.

Trained by Syd Swain for Robert Jones, also a prolific owner of thoroughbreds, Buck's Future followed his New Year's Day win in Gosford's Woy Woy Poultry Gold Cup Consolation by taking out the 520m Free-For-All.

Buck's Future, who has now won seven of 18 Wentworth Park starts, has struck top form at the right time with the heats of the Paws Of Thunder to be held this Saturday night at headquarters.

On Saturday, after battling for the early lead with Dual Keroma, Buck's Future gained control at the first turn and set up a clear lead on the back straight before comfortably holding out the fast-finishing Blue Moon Rising.

He won by three lengths, running home in a scorching 11.66s on the rain-affected track.

"When he jumps cleanly, Buck's Future will sprint hard to reach the lead and that's what he did tonight,'' trainer Swain said.

"But if he misses the kick he pulls back to find the rails and then he has to come from behind.''

Zipping Falcon (pictured), who had no luck when a distant second to Buck's Future in the Gosford Cup Consolation, also staged an impressive rehearsal for the Paws Of Thunder with an amazing win in a 520m fourth grade on Saturday.

The Jason Magri-trained Zipping Falcon "walked'' out of box one and was giving the tearaway leader Caitlyn Keeping over a dozen lengths' start at the half-way mark.

But Zipping Falcon "unleashed'' over the final 150m to win running away in 29.88s, coming home in 11.84s.

Rostered On, another Paws Of Thunder hopeful, bettered Zipping Falcon's time with a 29.82 overall and 11.76 run home effort in another 520m fourth grade for owner-trainer-breeder Chris Carl.

Rostered On trailed brilliant beginner Esther's Bella to the back straight but took over soon after and careered away to score by five lengths.

Carl, who will have Rostered On and Fast Car Driving in the Paws Of Thunder heats, has had a tremendous run of success with the siblings, along with their litter-mates Curtain Call and Rhythm Section.

"They are not as good as John Finn's litter comprising Poco Dorado and company, but they have been terrific money-spinners and have won over $200,000 in prizemoney,'' Carl said.

While Poco Dorado wound up her preparation for Saturday night's Summer Distance Plate with a near record Richmond 618m win on Friday night, her sister Veloce Nero sneaked under the 30sec barrier with a comfortable 520m win at Wentworth Park on Saturday night.

Veloce Nero, a luckless second to Zipping Falcon over 520m at Wentworth Park on December 29, began well on Saturday and after chasing Ancient Secret most of the way, surged to the lead on the home bend to win in 29.99s.

She will be back over her preferred distance, 720m, for the Distance Plate heats, as will her litter brother Blue Moon Rising, who flashed home when second to Buck's Future in a shorter race on Saturday.

Champion Model notched her 25th win in a 520m third and fourth grade at Wentworth Park on Saturday and her bid to win the Paws Of Thunder could bring down the curtain on her remarkable career.

Winner of the 2018 Goulburn and Canberra Cups double, Champion Model has been ear-marked for the breeding barn when her current campaign is over.

"She is due to come in season in the not too distant future and when that happens she will be retired,'' trainer Jodie Lord said at Wentworth Park on Saturday night.
