Jockey changes happen all the time, but there's one this week that's left trainer Mick Price feeling a little guilty.

Champion jockey Damien Oliver will replace Zac Spain on Frondeur in Saturday's Group 3 Kevin Hayes Stakes, with Price labelling the talented three-year-old as one that has black-type quality.

Spain rode Frondeur (Roc de Cambes) to a comfortable victory at Pakenham in a Benchmark 64 last start, while Dean Holland rode her when she strutted to a 3.5-length win on debut.

But Oliver will now have the mount with the filly taking a big step up in grade.

"Zac makes way for D. Oliver, but anyway, Zac is one of our jockeys and we put him on some nice horses … I feel guilty there, don't I?" Price said at Sandown on Tuesday morning.

"She's got a little black-type factor about her, I reckon, just working her. She worked on the course proper (at Caulfield) this morning, Ollie rode her.

"She's a good Kiwi filly that I think is black type. We gave her one run on a Heavy track, tipped her out, she had enough and then one run the other day and she was very good."

Prince said he was hoping for a wide draw for his filly on Saturday, which would allow Oliver to ride her to her strengths.

"The only thing I'll say, (is in the) Kevin Hayes, (I am) hoping it sort of draws out a bit. In a 1200-metre race it gets back a bit, and it has a very strong finish," Price said.

"To win the races we've won on her in the country, she has drawn bad and we've decided to just let her find her feet and work home strongly and she's just been too good for them.

"I'm not saying it can't win if it does get back. (But) I can't wait to it gets to 1400m, a mile and we can ride a proper race on it."
