Slazenger thirds pulled away from Bradford fourths in the final quarter to sink three goals and take a 4-1 win from what had, until then, been a closely-faught, highly paced encounter.
Scorers for Slazenger, after Bradford had stung the Horbury side with a breakaway goal, were Richard Whawell, Andy Auty and James Swinden.
On Saturday, Slazenger thirds take on Bardsey thirds at Addingford Fields, 12 noon start.
