Baseballer receives sanction

Sport Integrity Australia

Sport Integrity Australia today acknowledges the decision of Baseball Australia to impose a two-year ban on athlete Zachary Wilson for the presence of a prohibited substance.

Mr Wilson, who played for the Canberra Cavalry in the Australian Baseball League, returned an Adverse Analytical Finding (AAF) from an in-competition doping control test on 15 January 2021 which detected the presence of 5-methylhexan-2-amine (1,4-Dimethylpentylamine).

The substance 1,4-Dimethylpentylamine is listed under class S6.B ‘Specified Stimulants’, and is classified as a Specified Substance under the World Anti-Doping Code. It is prohibited in-competition only.

Mr Wilson is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 25 September 2023.


The substance 1,4-Dimethylpentylamine is similar in structure to 1,3-dimethylamylamine (DMAA), which can cause side effects including cerebral haemorrhage and heart attacks and has been linked to a number of deaths in Australia and overseas.
