Brett Houston scored the only century of the day in the Readers Lincolnshire ECB Premier League as Bracebridge Heath recorded the highest team total against Louth to move into third place in the table.
Haxey and the current league champions both leapfrogged Woodhall Spa, Haxey going second after bowling Woodhall out for 136 and going on to win by six wickets to stay ahead of Bracebridge by one point.
Houston's unbeaten 104 took him over the 300 run mark for the season and his side to 241 for five. Five wickets for Matt Bradley then helped bowl Louth out for 84.
But Skegness marched on at the top, keeping the gap to ten points after Peter Houghton had hit another 88 runs against Sleaford to become the second player to top 300.
Alex Sears took five wickets as the seasiders were all out for 197 but Oliver Pringle then took five and Oliver Burford hit 52 as Sleaford were all out for 143.
Hartsholme recorded their first victory of the season at home to Market Deeping.
New signing Liam Moir-Holland hit an unbeaten 47 as Hartsholme reached maximum batting points with 229 for seven.
Jake Benson and Henry Rush each took four wickets to bowl the visitors out for 137, of which John McDougall made 61.
This moved Hartsholme out of the bottom two as Lindum were pushed down to 11th place following the tightest game of the day at Augusta Street where the Lincoln side were bowled out for 156.
In reply, Harry Warwick hit 52 and Grimsby looked to be closing in on victory with 20 needed off the last six overs and four wickets in hand. However, Luke Robinson's three wickets in eight balls put his side back in the game and with nine down at the start of the final over, the home side were fighting for survival.
Matthew Cocks was left facing the final ball of the match with four still needed for victory but experience won the day as Cocks launched a six over long off to give his side a welcome 20 points that moved them up to sixth behind Bourne who added to Boston's woes at the bottom of the table.
The Mayflower team were again bowled out cheaply, scoring 118 at Abbey Lawn, where Jack Berry's 52 helped Bourne to a five-wicket win.
In this weekend's fixtures, Haxey are again involved in the pick of the Lincolnshire ECB Premier League matches.
Haxey have to overcome the challenge of third-placed Bracebridge Heath to stay in second place.
Current champions Bracebridge, who are again without skipper Paul Cook through injury, trail their opponents by one point and are 11 behind leaders Skegness.
The top team are away at Market Deeping whose batting has let them down in their last two games and will find the going tough.
