 In his first three seasons at The Dell he only made fifteen appearances including a spell of ten games in the latter half of the 1925–26 season when first Dominy and then Rawlings were unavailable in which Bullock scored four goals, including a brace against Derby County on 10 February 1926.In the following season, although Dominy had now moved on to Everton, Bullock was again unable to secure a regular place as Saints had signed Dick Rowley who became the first choice at inside left.Rowley was injured in early December 1927, and after briefly trying Charlie Petrie at inside left, manager Arthur Chadwick moved Rawlings across and played Bullock at centre-forward.
