A breakthrough win at Randwick could be the catalyst for Shootoff to go one better than his sire Duelled in the Victoria Derby.

The rising three-year-old is trained by Graeme Rogerson who also prepared Duelled who ran a close second to Benicio in the 2005 Derby.

He went amiss shortly after and became the first son of Redoute's Choice to stand in New Zealand where he resides at Rogerson's Dormello Stud.

Shootoff's win in the Chifley Handicap (1550m) gave him the honour of being Duelled's first race winner and co-owner Pasquale Stramandinoli was excited about his prospects.

"The Victoria Derby, that's what we want," Stramandinoli said.

"His sire ran second and we want to run first."

Shootoff gathered in his opponents to score a three-quarter length win over Reem in impressive fashion.

He gave Blake Shinn the first leg of a winning double but riding honours were with Nash Rawiller who claimed three on the program including a double for Gai Waterhouse on Suki and Fusakeo.

Corey Brown hit back with one to leave him six behind Rawiller in the battle for the Sydney jockeys' premiership.

Brown's win on Spence in the Maroubra Handicap (2400m) was a breakthrough for trainer Lisa Cohen who has a small team at Hawkesbury.

"This is my first winner in town and it's very exciting," Cohen said.

"I've got six horses in work. We are really just getting going and the horses we've got are nice horses.

"It's wonderful being where we are in the lower Blue Mountains.

"There's a lot of room and the horses love it."

Cohen spent some time learning her trade at Rosehill with Chris Waller who had a rare winless day but still maintained a nine-win buffer over Waterhouse as they battle out second place on the trainers' ladder.

Peter Snowden also ended the day as he began on 90 wins for the season as he heads towards his first premiership and the first for Sheikh Mohammed's Darley Australia.

However, Snowden is not resting on his laurels.

"July 31 is when the premiership happens, I don't want to talk about it until then," he said.

Darley will be without their retained rider Kerrin McEvoy until the late spring after he suffered a back injury at Gosford last week.

The stable's number two jockey Josh Parr is currently serving a suspension.

"We will be trying to get the best jockeys we can over the next few weeks," Snowden said.
