Adams's bowling action is highly unorthodox and Mike Gatting famously likened it to a "frog in a blender". Though his action initially caught world batsmen by surprise, he was soon exposed for lack of variety by the Australians. As such, he became less effective. However in December 2006 he was recalled to the Test side for the series against India, only to be dropped from the squad before the first Test.
