Trainer Norm Jerrick hoping luck is on Playa Blanca's side at Riverina Paceway on Friday

Jerrick is aiming for the Somebeachsomewhere filly to break through at her third run, in the Canadian Club 2YO Maiden Pace (1740m).

"It's the draws that kill us," Jerrick said, after she draw barrier eight for the second time in a row.

"She's working well. She's just a very green two-year-old filly but she she keeps drawing the worst draw of the race so it's a bit hard from there. But she's going well."

Last start, Playa Blanca ran a strong second behind the impressive Goulburn runner, Dance Away, which did just that in the straight, to win as a $1.40 favourite for Neil Day.

"He was much too good for us but she ran an extremely good race. She surprised me how well she went and I think she might have trained on from there. I'm rather pleased with her," Jerrick said.

Goulburn horses won five of the eight races at Riverina Paceway at that July 3 meeting which was the first after the 'regionalisation' rules were relaxed, allowing horses and trainers to travel outside their own zone.

But Harness Racing NSW has had to bring back the policy already, announcing that regionalisation will return next week "as a precautionary measure and to facilitate the continuation of harness racing in NSW".

The COVID-19 scare in Sydney has forced the governing body to go back to containing racing within separated Metropolitan, Western, Northern and Southern regions, preventing trainers from going outside their regions.

Harness Racing NSW said it's mindful of the impact it will have but said it's required to protect the industry and the livelihoods of those who work in it.

The policy comes into effect at midnight on Sunday.

Playa Blanca is one of four horses Jerrick has in work, all two year olds.

"Whether we'll get runs or not, I don't know. There's not a big field of two-year-olds in work in the Riverina, I don't think, which is a bit of a worry," Jerrick says of the tightening of rules again.

"We're only getting eight runners at the moment with a few dropping out. Hopefully I'll have my four up and running and that'll make half a race ourselves!"

Jerrick expects the dangers in the first on Friday to be some of those that finished just behind Playa Blanca in the maiden two weeks ago, Treacherous One (third, trained by Glen Wilmot) and Illawong Kelly (fourth, Bruce Harpley).

Adam Richardson is the pilot for Playa Blanca again.

"We'll just do what we did last time, come across and hopefully get a sit somewhere. We'll probably be back in the field. There's not much good slaughtering her out of the gate, drawing eight. We'll have to go back and hopefully get a bit of luck," Jerrick said.

"She's a very honest little filly, she's never put a foot wrong in her life and she's got good gate manners so that helps."

The race is the first of eight on the card at Wagga, which begins at 1.42pm.
