Ferguson had to fight hard for runs in the 2014–15 Matador BBQs One-Day Cup as South Australia had a poor tournament and finished as the bottom-placed team. In their opening match of the season against New South Wales, Ferguson had to rebuild the innings as the Redbacks had collapsed to 3 for 23. He top-scored with 82 and forged a 136-run partnership with Alex Ross. Against Queensland he was the only batsman for South Australia to put up a fight, scoring a 91-ball 98 in a team total of 257. He again saved the Redbacks from disaster, though they were still unable to win, against Western Australia at the end of the tournament, scoring a run-a-ball 82 to top score again.
