Bourne moved above Market Deeping in the Lincolnshire ECB Premier League table after a day of contrasting fortunes for the A15 neighbours.
The reigning champions delivered an impressive team display on the coast to see off Skegness by 85 runs while Deeping suffered a shock four-wicket reverse away to Grimsby.
Conrad Louth (56) top-scored in Bourne’s 221-9 before Colin Cheer (4-37) and Martin Shillito (3-36) ripped through the top of the Skegness batting order.
But Deeping wasted good starts to both innings as Chris Jones (51) helped them to reach 81-0 in a final score of 185.
Two early wickets for Patrick Brown reduced the home side to 20-3. Dropped catches and some less-than-accurate bowling proved crucial.
Spalding continue to fight for their lives at the bottom of the table as they scrapped hard for a draw at Market Rasen. Ben Smith’s second successive half century steered Spalding to 177-8 in reply to Rasen’s 190-8.
