The 2009 Diamond Anniversary Claxton Shield was the 75-year anniversary of the Claxton Shield and was held from 2 December 2008 to 8 February 2009 and was the Shield's Diamond anniversary. The Perth Heat won the tournament after defeating the New South Wales Patriots 3–2 in the third game of a best of three series. This historic tournament served as the final edition of the Claxton Shield as a standalone national competition before its integration into the newly formed Australian Baseball League (ABL) in 2010. The victory was particularly significant for Western Australian baseball, as it represented Perth's first Claxton Shield title since 2001 and demonstrated the growing parity among Australia's regional baseball programs.
