The talented jockey, and partner of local trainer Tim McIntosh, saluted the Bushland Drive judges aboard Mummentum and Fanciful Dream for Newcastle mentors Kris Lees and Paul Perry respectively.

Clenton created history at Rosehill in June when she, along with Jenny Duggan, became the first mothers to win Saturday metropolitan races on the same program in Sydney.

She'd previously suffered crushed vertebrae in a fall at Scone in October 2016 - and told she was lucky to be walking.

As she was recovering, Clenton and McIntosh welcomed Isaac to the world.

On Friday, she guided Mummentum (Lees) to victory in the R&L Refrigeration F&M Maiden Handicap over 1250m.

The four-year-old bay mare, having just her second start, upset $2.60 favourite Trajection (trained by Kim Waugh) by more than a length, with Neil Godbolt's Dynasty Di in third.

It was the New Zealand-born galloper's first triumph, too.

Clenton then backed up to capture the last, the Taree Leagues Sports Club Benchmark 58 Handicap over 1000m.

Fanciful Dream (Perry) went in as the pre-race choice - and lived up to all expectations, enjoying a two-length win at the expense of Impulsive Maneuver (Jim Jarvis) with Dragoneight (Luke A Thomas) rounding out the placings.

The result made it back-to-back victories for the three-year-old filly.

Singleton hoop, and regular visitor to Muswellbrook, Aaron Bullock also returned home with a hat-trick of triumphs.
