Caistor suffered a wobble before securing a Premier League victory in the Readers Lincolnshire Cricket League last weekend.
Barton Town were all out for 104 when they visited Marsh Lane before the home side struggled to their victory target, reaching it eight wickets down in the 31st over.
Best performers in the Caistor attack were Sean Woolley with 6 for 41 and spinner Kieron Brooker with 4 for 47.
Brooker also top scored with 21, while Liam Wood contributed with 17.
* In Division Four, Caistor Third XI made 118 before going down by a single wicket to Cleethorpes Fourths who replied with 123-9.
Caistor’s respectable total on a decent wicket at the Immingham Blossom Way ground was thanks mainly to Sam West whose patient 30 in damp conditions was the bedrock of an innings where no other batsman passed 16.
Sachin Meher took 4 for 48 when Cleethorpes replied, well supported by Tim Gillott and Aaron Nevin with two wickets each.
* The first round of the Bob Welton Cup featured many of our local teams.
It was not a good day for Brigg Town who were all out for a paltry 32.
Appleby-Frodingham Seconds had no trouble in reply, getting to 33-3 for a seven-wicket win. Nick Beacock did claim three wickets with his left arm medium pace, but no Brigg batsman was able to hit double figures.
Caistor Seconds turned in a solid effort with both bat and ball against Cherry Willingham Seconds who were dismissed for 101.
Pick of the Caistor bowlers was Henry Gillott with three victims, while Oliver Barrick and Ben Young took two each.
Caistor sneaked home with 105-9 for a single-wicket win thanks to Gillott’s unbeaten 25 and Luke Francis (25) who combined to see them home.
Clee Town Laportes beat Market Rasen Seconds on the toss of a coin to go through to the next round after no play was deemed possible because of the ground conditions.
It was the same outcome as Grimsby Town Seconds went through at the expense of Keelby Seconds.
Hibaldstow were more fortunate in getting a game in between the heavy, and even wintry, showers, but they lost by the smallest margin of one run.
Their opponents Old Lincolnians hit 89 with Tom Taylor taking a match-defining five wickets for 10 runs from nine overs.
Mark Nicholson top scored for Hibaldstow with 21, but his side fell one run short in their reply, dismissed for 88.
