James Darren Siddons (born 25 April 1964), commonly known as "Jamie", is an Australian cricketer, renowned for his involvement in Sheffield Shieldfirst-class cricket over a 16-year career. He initially played for Victoria, and later for South Australia. He is currently a professional cricket coach.
On 23 November 1997 he broke David Hookes' Shield run record of 9,364, going on to make 10,643 runs in 146 games. He is now the third highest run-scorer in the Shield's history, behind Darren Lehmann and Jamie Cox. He is considered by some to be one of the finest batsmen in Shield competition not to receive a regular international spot, having been given just one opportunity to represent Australia in a One Day International (ODI), in 1988, scoring 32.
