SISTERS Breanna and Rhiannon Griffiths are both promising junior athletes.
The Prestons siblings are discus and shot-putt throwers.
Breanna, 10, and Rhiannon, 6, are members of Prestons Robins Little Athletics Club.
The girls attend Dalmeny Public School: Breanna is in year 5 and Rhiannon year 1.
Breanna recently competed at the regional Little Athletics titles winning two gold medals in the under-10 girls' shot-putt and discus events.
She threw 8.12 metres in the shot-putt and 26.69 metres in the discus.
Her father Chris said that Breanna had also won the under-9 discus state title last year.
She is coached by David Prior at the South West Sydney Throw Squad.
Rhiannon joined Little Athletics this season and in her first zone-level competition won the discus in the under-7 girls' age group, throwing 11.63 metres.
At this year's state titles, Breanna was back again to defend the discus title which she won in 2013.
This time she won bronze, throwing a personal best of 30.56 metres.
She was the club's first state medallist last year and its only state medallist again this year.
