Angela and Ryan became the first Queensland-based siblings to combine for a metropolitan win in the state when Sugar Sizzle ($9.50) beat Red Doulton ($5) by a neck.
Angela Plumb has been training for about three years after starting off in Victoria where she originally worked at a pre training centre.
But she returned home to the Gold Coast 18 months ago where Ryan was the leading jockey last season.
“Sugar Sizzle is the only horse I have in work at the moment and there is room for a few more,” she said.
“I went to university in China and which is how I got this filly for an Aquis Farms syndicate, through the Chinese connection.
“That was my first metropolitan winner and what a way to do it with Ryan. I didn't give him many instructions but he is two from two on her this season so I might keep it that way.”
The Plumbs are the children of former top jockey Lyle Plumb junior and the grandkids of jockey-trainer Lyle Plumb senior.
“Racing has been part of our family for along time and we support each other,” she said.
