Trainer Less Ross and owner Mike Cooks' Mishani Enterprises had six of the nine staters for the first 2-year-old race of the season, Saturday's Pat O'Shea 2yo Plate (1000m) at Toowoomba, and duly supplied the trifecta.
The outsider of the sextet, Mishani Rock, handed the hammer blow to punters.
Ridden by Les Tilley, the son of Kobayashi was strong to the line in defeating the Kobayashi filly Mishani Ego by one and a half lengths, with The Mission filly Mishani Fire back in third.
"It was a pleasant surprise. I was hoping one of the fillies would win, but it's nice to have a winner," Ross said.
"I had a great season (with Kobayashi), with Mashai Royale and Gangster. They were two nice horses, and we might have a few this year with a bit of luck.
"I’m lucky to have the staff from Mishani here today – Lacy and Donna – and it’s nice to have the whole crew here.”
Bred by Mishani Enterprises, Mishani Rock was not offered for sale as a yearling.
He is the third winner from four to race for the winning Oratorio (IRE) mare Gina Ballerina, a $1,500 purchase from Royston Studat in the 2014 National Yearling Sale.
Gina Ballerina’s granddam Cinibar (Bluebird) is a half-sister to the dam of Group 1 BTC Doomben Cup winner Cinque Cento.
Gina Ballerina was not covered last spring.
Kobayashi stands at Aquis Farm for $8,800.
