An untapped three-year-old has part-time trainer Kelvin Barker and his son Mitchell dreaming of group race glory this Saturday night at Tabcorp Park Melton.

Urbadboy is the horse the Barkers are excited by and it’s no surprise given just how good he’s been since arriving at their Mitchell Park stable a couple of months ago.

The only winning son of former star pacer Restrepo, Urbadboy arrived from South Australian owner-trainer Andrew Clarke with a record of one success from eight starts. That modest form quickly improved when his first two runs for the Barkers produced a 13.4-metre win at Kilmore in late February and then a 34.8-metre thrashing of his rivals - in a slick 1:55.9 mile rate - at Charlton last Sunday.

“(Andrew) always told me he had the ability and (now) he’s working with better class horses at home,” Kelvin Barker said.

“He had an opinion of the horse, don’t get me wrong. We haven’t done wonders. The horse had the ability before it came to my place.”

Barker, who works a full-time job as a waste truck driver and shares training responsibilities with Mitchell, said Urbadboy’s ability remained somewhat of an unknown.

“Everything we have asked him to do, he’s done,” he said. “Mitchell said to me one day working him ‘I think this might be the best horse we’ve had for a long time’.

“We don’t really know how far he’s going to go or how good he is. The first start, we thought he was a great chance of winning against Emma Stewart’s horse, but we didn’t really know. And he did it so easy.

“And then at Charlton it was a bit of a step up in class again and he improved, I thought, and did it easy again.”

Barker paid tribute to his son, who he said worked long hours and helped keep the stable ticking over.

“Mitchell works very hard. We work very long hours and without Mitchell I wouldn’t have these horses, I tell you. Because I wasn’t prepared to take any more horses on,” he said.

TUNE INTO TROTS VISION SATURDAY NIGHT FROM 5.25PM FOR MELTON'S 11-RACE CARD

Urbadboy is one of the real interesting runners in this Saturday night’s Group 3 VHRC Victoria Sires Classic (2240m) at Tabcorp Park Melton, where he will take on a quality field of three-year-olds.

Stewart-trained Pacifico Dream, who finished fourth in the NSW Derby at his most recent start, is the horse to beat and will likely go around as a warm favourite. Craig Cross-trained Youaremy Sunshine was sixth in that race behind Pacifico Dream and is another of the leading contenders.

There’s a bumper card of racing at Victorian headquarters this weekend with the headline event being the $50,000 City of Melton Plate XXXI (2240m, 4&5YO) at Group 2 level. The Allied Express Jodie’s Babe (1720m) is a Group 3 for the mares, while the Group 3 Economix Scotch Notch Memorial (2240m, NR 80-120) will see star trotter Tornado Valley run as a short-priced favourite.
