Greenmount consolidated their fifth position in the table thanks to an imperious batting display from captain Andy Kerr and Ryan Senior against Kearsley.
Kerr put on 120 while Senior made an unbeaten 109 as Greenmount posted a daunting total of 306-4 from their 50 overs.
In reply, Kearsley were on 122-4 from 26 overs when rain stopped play and the home side claimed the points on run rate.
After the match Greenmount chairman Dave Willets was delighted with his side’s performance.
“We’ve won the last three or four games but we had a very bad start to the year, which has cost us a bit.
“The bowling has been very good but the batting hasn’t been clicking together.
“Last weekend it just all seemed to click into place with Kerr and Senior giving us a good start.
“We just need our pro Akbar Ur Rehman to get in on the runs now. As soon as he starts scoring I think we will be something to contend with.
Bowlers Mark Stewart and Phil Heaton have also been in great form this season for Greenmount and Willets was quick to praise their performances.
“They may be in their 40s but the two oldies are evergreen and just keep going.
“They keep themselves fit, are good bowlers and are the ones that keep getting the wickets for us.
Greenmount, who have won seven of their 13 games so far this season, are 28 points behind league leaders Farnworth Social Circle and Willets knows it will be a tough task to catch them.
“It’s going to be difficult to catch Farnworth SC, who are currently running away with the league as we have to rely on the teams above us losing.
“The important games are when we play the top teams again. Those are the games we are really going to have to win.
“I think it is more a case of us trying to qualify for the Lancs Knockout now.
