The Manchester-born Jimmy Bullock made his League bow with Crewe as an inside-left in 1924. He spent five years at Southampton but rarely rose above reserve level, despite a promising return of 13 goals from 32 starts in their first team. He enjoyed a 17-game spell when tried at centre-forward in 1927-8, scoring eight times, but was soon pushed back into Southampton’s reserves, where he is reputed to have scored 166 goals from 208 games.
Bullock was recommended to Chesterfield by Alec Campbell, their former manager, who enjoyed a long association with The Saints. Upon joining as a centre-forward in the summer of 1929, his career took off. 31 goals came from 39 appearances, including a run of eight goals in three successive home games. A five-game barren spell at the start of 1930-1 saw Chesterfield display a ruthless streak, accepting a £1250 offer from Manchester United for his services. The sale drew criticism at a time when the club were among the division’s early front-runners, but a month later, Albert Pynegar arrived. His 26 goals in 29 games helped the club to promotion that year and made Bullock's excellent-looking efforts a distant memory.
Jimmy couldn’t maintain his Chesterfield form in the division above and moved on after less than a season to Dundalk, then Llanelly, a semi-pro side from south Wales. A year after that he returned to the Manchester area and signed for Hyde. Jimmy had form as a professional runner and represented the Welsh League versus the Irish Free State in 1932.
For Chesterfield: 45 Football League appearances, 32 goals.
