Simpson then made his second double-century in as many innings, posting 230 not out in an innings win against Queensland, more than 57% of his team's runs. His innings of 79 in the draw against South Australia was his lowest score of the season and ended the summer with 98 and 161 not out against New South Wales, carrying his bat in the second innings of a defeat and again scoring the majority of his state's runs for the match. Simpson reflected that "I spent two years turning myself into an overnight success."
