A stakes race win to Malibu Style at Caulfield has not only given jockey Steven Parnham his first Melbourne winner but also formed part of a unique feat for the prominent West Australian racing family.

Only minutes after Steven guided the horse trained by his father Neville to victory in yesterday's Listed Bel Esprit Stakes, one of his younger brothers, Chris, also scored a stakes win in Adelaide aboard the Lloyd Kennewell-trained Viddora in the Gr. 3 RN Irwin Stakes.

And Steven and Chris' winners came after their other jockey brother Brad had ridden the winner in the first race at Ascot in Perth.

"All three of us have ridden a winner today in all different states," Steven said. "I don't know how rare that is."

Perth-based Steven, 31, is the oldest of the brothers and had been knocking on the door of a Victorian win after being placed five times in previous visits, including a couple of times in Group One races on Playing God in the 2011-12 season.

A three-time Group One-winning rider in his home state, Parnham had also come close to a Melbourne breakthrough this season, beaten less than a head in two Group Two races on Ellicazoom, while Malibu Style was second in his Victorian debut this month.

"I've had a handful of placings and they've been in feature races which has been exciting but to get the win has topped it," Parnham said.

Both Steven and Neville Parnham are convinced Malibu Style, who had won six of his 27 starts in the west, has thrived in his three weeks in Melbourne and that was shown with his latest performance.

Malibu Style ($21) sat just off the leaders Rocket Tommy and Faatinah before cruising up to them rounding the home turn.

He sprinted to the front inside the 300-metre mark and powered clear to beat Legless Veuve by two and a quarter lengths, with the favourite Crystal Dreamer another nose away third.

"He has really, really thrived here and I don't think I've seen him looking better," Neville Parnham said. "At home he tended to get a bit edgy before a race but he's nice and settled here.

"This was the race I picked out which I thought might just suit him and we had a race a couple of weeks back over 1000 metres and he performed very creditably."
