Slazenger were left disheartened after Bradford scored with the last touch of a game that the Horbury side should have won easily after missing numerous chances.
After early pressure Bradford took the lead following a good short corner strike.
This spurred Slazenger into action and they started to contro lthe game with Tim Carr thwarted by the Bradford goalkeeper before James Walker brought the scores level.
After the break, Slazenger remained in control, creating some great opportunities but it was Bradford who took the lead through a heavily contested penalty flick decision.
Once again, Slazenger raised their game and it was Walker who brought them level again.
The Horbury men had the chance to kill off the game, Richardson and Hutchins before Bradford nicked it at the death.
Matt Birkett showed some good footwork throughout and Ben Wells made some great challenges in defence.
Slazenger will look to bounce back this week against Lincoln 2nds
