Lincolnshire earned a place in the Unicorns Minor Counties Knockout Trophy quarter-finals for the first time since 2010, with victory at Cumberland.
They made two changes from the side which beat Shropshire, Conrad Louth and Martin Weightman replacing Anish Patel and Dan Freeman.
Cumberland won the toss and put Lincolnshire into bat knowing that rain was forecast in the late afternoon.
After the early loss of Paul Cook, Sam Kelsall and Conrad Louth took the total to 62 before Louth was out for 18.
Lincolnshire were eventually dismissed for 141 in the 44th over.
Kelsall top scored with 44, the only other score of note being 28 by Matt Carter, an innings that was ultimately to prove decisive.
Lincolnshire made an excellent start with two early wickets from Alex Willerton and David Lucas leaving the home side 11-2.
There then followed Cumberland’s best stand of 45 with opener Karl Turner dominant, but Willerton got him for 43.
Cumberland passed 100 with five wickets down and then lost three in quick succession for one run to slump to 104-8.
At 113-8 off 39.1 overs the rain fell and no further play was possible, Lincolnshire securing victory by virtue of their superior run rate under the Duckworth Lewis method.
Alex Osmond with 3-13 was Lincolnshire’s most successful bowler.
Lincolnshire will now progress to the quarter finals where they will meet Norfolk at home on Sunday 14th June.
