Slazenger fifths dominated the first 20 minutes of their away game with Bradford fourths but eventually fell away to lose 6-2.
Bradford stunned Slazenger by surviving the initial storm then racing into a 4-0 lead, but Stuart Burnside pegged one back and Rob Stevens first-time strike put the visitors back in the hunt.
However, as Slazenger pressed for the goals they fell prey to the counter attack, and twice Bradford struck to finish with a four-goal cushion unjust in Slazenger eyes because of a series of disputing umpiring decisions and the spoiling tactics of the home defence.
