Muswellbrook-based apprentice Samantha Clenton creates a piece of history at Saturday's Rosehill meeting

JENNY Duggan and Muswellbrook-based Samantha Clenton created history at Rosehill, the pair becoming the first mothers to win Saturday metropolitan races on the same program in Sydney.

Both are mature-age apprentices whose careers have been interrupted firstly by injury, then by parenthood.

Duggan won on the Jason Coyle-trained River Bird on Saturday while Clenton was successful on Nicci's Gold for trainer Gary Portelli.

Duggan and husband Ben already had eldest child Maddi when she was riding at her peak and after suffering a serious leg injury in 2014, she has added two sons to her brood.

She returned to riding last year and recently claimed the Rising Star series for NSW apprentices.

Clenton, who has six rides on her home track at Skellatar Park on Sunday, suffered crushed vertebrae in a fall at Scone in October 2016 and was told she was lucky to be walking.

As she was recovering, she and her partner local trainer Tim McIntosh welcomed Isaac.

Clenton is indentured to Kris Lees at Newcastle and gets up at 2.30am to travel from Muswellbrook for trackwork.

She said Nicci's Gold had taken natural improvement from her first-up fifth two weeks ago.

"She probably got further back than I wanted but it all worked out in the end," Clenton explained.

She'll saddle up on Nomoretawq (for trainer Peter Eggleston), Star Alibi (Jason Deamer), Kulnura (David Atkins), Apache Junction (Todd Howlett), Powerline and Charlie's Law (Kris Lees) at Muswellbrook's Aberdeen Cup meeting on June 16.

Gates open from 11.30am.
