Bracebridge Heath and Woodhall Spa remain locked in battle at the top of the Readers Lincolnshire ECB Premier League, just two points between them.
But reigning champions Bourne slipped to fourth after going down to near neighbours Market Deeping by five wickets, a victory that moved Deeping into third, just 10 points off second place.
At the foot of the table, only seven points separate the bottom three after Spalding scored their second win of the season while Grantham and Grimsby lost.
Spalding were involved in a nailbiter at Skegness, having batted first and been bowled out for 213, Luke Hollingworth hitting 53 and Brendan Young taking five wickets.
Skegness then made steady progress towards their target but were still two runs short when the final batsman was dismissed.
Nick John hit the day’s highest total of 97 at Market Rasen where leaders Bracebridge finished on 275 for seven, Paul Cook making 50.
Rasen’s reply stuttered from the start as Himesh Silva dismissed four of the home side’s top order for just 16 runs.
Matt Carter then joined the attack to take five for 20 as Rasen were all out for 88, putting them on level points with Skegness in eighth place.
At Market Deeping, Patrick Brown took five for 53 to help bowl Bourne out for 194.
In reply, Alex Wheatley made 63 and Ajaz Akhtar 51 as the home side claimed a valuable victory.
Lindum won the toss and elected to bat at Woodhall Spa - but only one player made double figures.
Charlie Tomlinson hit 71 out of his side’s total of 108, Luke Smith taking five wickets for 21 runs, four of them clean bowled.
Woodhall lost four wickets, three of them to Jonny Miller, before reaching their target in the 28th over.
Andy Carrington took six wickets at Grantham as the league newcomers looked like threatening their visitors’ total of 196 for seven.
Amila Wettasinghe (58) and Matt Hamilton rescued Louth’s innings which had slipped to 86 for four, putting on 51 for the fifth wicket.
Wettasinghe and Carrington then reduced Grantham to 70 for five before Rohan Nurse and Jamie Brumby added 92.
Both then fell to Carrington, Nurse making 59, and the lower order had no answer to the Louth skipper’s bowling, the last wicket falling on 177.
This keeps Grantham two points above bottom side Spalding and five behind Grimsby whose bowling restricted Sleaford to 179 all out.
Connor Hawkins reduced the visitors from 64 for one to 76 for five before Oliver Burford (52) joined Andy Hibbert in a partnership of 72.
Hawkins took six for 58 off 17 overs but once again Grimsby’s batting proved to be their weak point, the first wicket going on 20 followed by a steady procession back to the pavilion, only Joe Farmery and Lee Charlton putting up real resistance as the home side were all out for 104.
