Had to go back to 2015/16 for the previous biggie we won, last home game of the season against Port vale keeping us in the hunt for automatic promotion.
I am being pedantic, but that was to keep us in the hunt for the playoffs. Also, I would argue that the 2-0 win at home to Plymouth in 2017/18 which virtually assured us of a playoff spot, while Plymouth winning would give them an upper hand, would class as a more recent big game win at home.
