Apprentice Blake Spriggs has confirmed he will be remaining in Sydney with the Gai Waterhouse stable.

Spriggs has been with Waterhouse on a three-month loan but the papers have been signed to make the move permanent, beginning next week.

The apprentice stole the limelight two weeks ago when he rode five winners at Rosehill including a first stakes win on Mr Unforgettable in the Listed Winter Stakes.

"I've signed over until the end of my apprenticeship," Spriggs said.

"I'm just taking it step by step but I'm happy to keep the association going long term."

Spriggs has set himself the target of winning the Sydney apprentices' premiership next season and said having the opportunity on Waterhouse's lightweight horses who stable jockey Nash Rawiller can't ride would be a big bonus.

At Warwick Farm on Friday, Spriggs' parents Dale and Leanda said they had been thrilled with their son's progress since moving to Sydney.

"It (the transfer to Waterhouse) has been sorted out over the past week, we've had a couple of meetings with Gai and we're very happy," Dale Spriggs said.

"We're thrilled, not just with the way he is riding but the way he conducts himself as a person."
