The table-topping visitors from Lincoln were dismissed for 180, giving Cleethorpes full bowling bonus points, but the hosts were then dismissed for 177 with seven balls remaining in the match, and only four more runs required for victory.
Stuart Wood and Jordan Cook, who later scored 35, both took wickets for the Meggies in the Chichester Road clash.
In-form Caistor Town 2nds' opener Andrew Pearson finished unbeaten on 71 as his team shared the points with Keelby in a game truncated by rain.

In Division Three, Grimsby team Laportes posted two half-centuries in their home match with top-of-the-table Alford 2nds.
But while no-one managed a 50 for the visitors, they secured a five-wicket win after a solid 'bits and pieces' effort.
Ian Rudland (58) and Gill Singh Palli (52), pictured, were the mainstays of home side's all-out 196.
Mark Elsom had Alford's best analysis of three for 19, despite being the sixth bowler employed, while keeper Sam Lempard chipped in with four dismissals.
