Three months after getting himself back on his feet following a horse riding injury, trainer Danny Williams is also gaining traction on the business front.

The Goulburn-based horseman added to his recent run of city success with a winning double at Canterbury on Wednesday.

Three-year-old Van Halen broke his maiden in the opening race before Napayshini was elevated to first place in the Hyland Race Colours Handicap following a successful protest by jockey Christian Reith against Thomas Huet who rode Radical Impact.

The Canterbury brace followed metropolitan victories by stablemates Istanbul and Bag Of Nickels last month to give Williams four city winners in the past five weeks.

Williams only returned to training last August after a stint working as foreman to Tony McEvoy at Hawkesbury.

And he is lucky to be training at all after his life took a twist at the start of the year when a horse he was riding bucked, shattering his pelvis.

"It sheared my pelvis apart," Williams said.

"I had two operations and spent 54 days in hospital.

"It's a struggle day-to-day but I'm getting better."

Success on the track is keeping Williams's spirits high and also fuelling his stable numbers.

He currently has 24 horses in work, and counting.

Van Halen was having his sixth start on Wednesday and Williams said he had earned a spell.

"He's showing promise but he's been a very slow learner," he said.

"I'll probably turn him out now. I'd say he has come to the end of his preparation."

Napayshini, who showed enough early promise to contest stakes races as a two and three-year-old, joined the Williams stable earlier this year and Wednesday's win was his first in almost two years.
