In Division I, Heywoods continued their 100% record but, unusually for them, were not too impressive despite beating Marsh Lib 6-1.
It took Irish 20 minutes to go 1-0 up as Lib keeper Michael Beaumont (an ex-Irish player) and Nick Jaggar went for a 50-50.
Beaumont missed the ball altogether and left Jaggar to tap it into an empty net.
Irish netted a further twice to lead 3-0 at half-time through Matt Tattersley and then a delicate chip by Darren Henighan.
The second-half started with a goal back for Lib, with Irish keeper Kevin Ashe spilling a speculative shot by Andy Morris over the line.
For a while Lib were encouraged by this goal, but in the last 15 minutes Irish added a further three goals as Lib’s spirit faded. Steve Perrin was allowed to go through unchallenged for goal four, Henighan added No5 and Nick Jaggar a free header.
In Division II, Kirkheaton Lib (who had previously won only once) are cock-a-hoop following their second successive victory, this being the first against Division II opponents. A Graham Dunn brace and Josh Havis gave them the 3-2 win over Gas Club.
At Inter-divisional level, Cricketers Arms failed yet again to beat a Division II side which means in their last four Inter-divisional games against the top four they have managed only one point.
This was against Thornhill Arms in a 5-5 draw. On target for Cricketers were Dean Johnson, Wayne Walker, Paul Wood, Marcus Thomas and Aaron Kirk, while in reply for Thornhill were Nathan Dennis and Odutola Kunle (two each) and Satinder Sandhu.
Cricketers have now literally blown their chance of success for this season, which is disappointing for them.
