Slazenger Thirds lost 2-1 to Normanby Park seconds in a game they dominated overall.
However, a failure to convert their chances cost the home side dearly.
Slazenger opened the scoring early on with a superb finish from John Sykes.
Normanby Park equalised on the break-away in the second half. Slazenger responded well and looked to have restored their lead but an early whistle for a foul resulted in a second short corner – from which Normanby Park broke away to score.
Despite constant pressure thereafter by Slazenger, they were unable to break down a now well-manned defence. Slazenger travel to Brigg thirds on Saturday, push back 2pm.
