Dan Kemp scored the only goal of the game as Stevenage secured a smash-and-grab 1-0 League One victory over play-off rivals Bradford.
The Bantams dominated the first half but were denied a third successive win by Kemp's fifth goal of the season, the forward striking against the run of play just after the hour.

Stephen Humphrys fashioned the first real chance of the game when he fired over the crossbar, while George Lapslie went close for the hosts when he flicked his effort wide of the mark.
