Isobel Ross drives three straight winners at Blayney meeting for Amanda Turnbull

Ross, currently working with Amanda Turnbull's stable, took three of The Lagoon trainer's runners - Chasing The Wind, Meraviglia and Sabreur - to wins.

Chasing The Wind ($1.85 favourite) crushed the field to win by 14 metres in the second Peter Marshall Memorial Heat (2,000 metres) of the day.

Meraviglia ($1.65 favourite) won by a similar margin when saluting in the Pringle Auto Service Pace (2,000m) before Sabreur ($4.60) won a very open affair in the Blayney Concrete Pace (2,000m) to claim the treble.

Ross had previously claimed three straight victories at a meeting during the earlier days of her driving career in Queensland but Sunday marked her first time achieving the feat in New South Wales.

"It's an amazing feeling. Even though they're Amanda's horses and everyone expects them to do well, you can't just expect to win because racing is racing," Ross said.

"After that second win I was quite nervous and I was really, really hoping that the next one could win so it was a great feeling when I crossed the line."

Chasing The Wind and Meraviglia entered their events as odds-on favourites but Sabreur was one of four horses starting under $5 in the last event of the day.

Sabreur found the lead and managed to find a small break on the turn for home, and was able to stay clear from a wall of chasers to give Ross the perfect finish.

Ross said Sabreur was somewhat of an unknown quantity on the Blayney track but she was thrilled by the way he found the line.

"We haven't had him for long in Sydney because he's been down with Amanda in Melbourne. Even though he did win his last start Amanda said he can be a bit of a surprise package and you never know what he could do," she said.

Sunday's other Peter Marshall Memorial Heat was won in dominant fashion by Mat Rue's Beast Mode, who sailed 30 metres clear of his rivals.

The final is on Sunday.
