With the bulk of the leading riders in Melbourne for the spring carnival, Josh Parr is seizing the opportunity to make an impact in Sydney.

Parr has landed rides for two of the country's top trainers at Rosehill on Saturday, Peter Moody and Peter Snowden, and is delighted at the chance to showcase his skills.

"I suppose when a few of the boys head to Melbourne it just gives you an opportunity to ride the better horses," Parr said.

"So you've got to make the most of it and luckily, a bit of luck has fallen my way so I'm very, very pleased."

While Parr has long had an association with Darley, he has made a special effort to build a relationship with Moody since Melbourne's premier trainer opened a satellite operation at Rosehill early this year.

The pair celebrated stakes success when Brilliant Bisc won the Gimcrack Stakes on Epsom Handicap day and on Saturday they will team with Soros in the Alpha Flight Services Handicap (1500m).

" I've been sticking my head in there (Moody's) and riding a fair bit of trackwork over there at Rosehill," Parr said.

"When he first started bringing horses here I thought it was probably a good opportunity to get my nose in the camp and I'm just doing my best I can over there.

"It's been terrific, especially to win the Gimcrack."

Moody thought highly enough of Soros to take him to Brisbane for the winter carnival races and he finished fourth to stablemate Brambles in the Group Three Grand Prix Stakes (2200m).

He resumed with an eye-catching third to Agueda over 1200m at Rosehill earlier this month with Parr in the saddle.

"His first-up run was well above average. We ended up back in the field on a track that was quite hard to make up ground on, " Parr said.

"He got to the outside and he possessed a really good turn of foot and attacked the line really strongly."

Parr's only concern going into the weekend is whether Soros, a winner up to 2000m, will already be looking for further than the 1500m of the Rosehill race.

"He's a horse that's going to stretch right out, as he's shown, to a mile-and-a-half (2400m) so the step up in distance can only help him," he said.

"I haven't been fortunate enough to gallop him in between his last run and Saturday's race so hopefully he's still sharp enough for the 1500.

"He's definitely a chance again."

Parr is also looking forward to linking with the Snowden-trained Bereft who resumes in the Harvey Norman Sprint (1200m).
