Lincolnshire have booked their semi-final place in the Unicorns (Minor Counties) Knockout Trophy.
For the last-eight tie with Norfolk at Grantham, they made three changes to the side that beat Suffolk in the Eastern Division Championship earlier in the week.
Paul Cook and Pete Morgan replaced the injured Karanjit Bansal and Anish Patel while Brett Houston came in for Adam Shepherd.
Continuous rain on the preceding day delayed the start by 90 minutes and when the match got under way Norfolk, having won the toss, elected to field.
At this stage the match had been reduced to 46 overs per side.
Paul Cook was dismissed early on then Conrad Louth (35) joined Sam Kelsall in a stand of 66.
Morgan then joined Kelsall in a stand of 87 before Morgan fell for 40, including three fours and one six.
Batting was difficult, in particular finding the boundary was a rare event.
From 166-2, Lincolnshire slumped somewhat and two further rain delays interrupted their progress.
These delays forced a reduction in their allotted overs to 42.
Kelsall was the fourth man to be dismissed for a well-constructed 73 and thereafter only Carl Wilson with a quickfire 20 reached double figures. At the end of their 42 overs Lincolnshire were 212-8.
As Lincolnshire’s innings had been reduced by four overs during its progress, Norfolk were set a revised target of 219 to win.
The highest stand they managed was 35 for their second wicket.
All six Lincolnshire bowlers took wickets.
The dismissals of Ben France by Houston for 41 and Jordan Taylor by Dan Freeman for 42 were crucial as Lincolnshire put the visitors behind the clock.
The inevitable came in the 41st over when David Lucas took the final wicket to dismiss Norfolk for 193.
Lincolnshire won by 25 runs under the Duckworth Lewis method to secure a semi-final visit to Northumberland on Sunday, July 26.
Kelsall (3-43) was Lincolnshire’s most successful bowler to add to his match-winning innings of 73.
