Grantham are now the only unbeaten team in the Lincs ECB Premier League after the weather denied Lindum the chance to keep their winning record.
But the Division South leaders were pushed hard by Boston, with some excellent fielding and catching from both sides keeping run rates down.
Boston elected to field first, Ross Carnelley and Jaden Fell opening for the home side with a steady stand of 59, but it was Ben Coddington who anchored the innings with an unbeaten 54,
allowing the middle order batsmen to hit out in the last few overs and push the score up to 194 for five.
Boston suffered an early blow, losing a wicket on two and two more on 27.
Two more fell to make it 56 for five and their target looked a long way off. But Tom Baxter and Luke Gilding had other ideas, picking off the runs until, having shared a stand of 107, Baxter was out for 52.
By now the overs were running out and Gilding was unbeaten on 42 as Boston finished 166 for six.
Louth welcomed back former player Andy Carrington for their game at Woodhall Spa but once again it was Richard Bell who set them on the road to victory,
Bell hit 77 and Jason Collinson was unbeaten on 44 as Louth made 231 for five, Alfie Lindsey taking three wickets.
Woodhall lost two early wickets and despite the efforts of Jack Hughes with 49 could not match the Louth total, the last wicket falling on 187.
Scunthorpe Town visited Bracebridge Heath where they were bowled out for 155, Andy Carter and Ben Whitehouse each taking three wickets and Karanjit Bansal top scoring with 38.
Martyn Dobson and Nick John then took the home side to 113 before Dobson was out for 54 and despite losing three more partners in quick succession, John was still at the crease with 53 when the winning runs came, Rounak Sen taking three of the wickets.
Pierce Morley-Barnes hit the day’s only century with 107 and Will Wright made 62 as Lindum racked up the day’s highest total of 235 for six. But the weather intervened and with Bourne on 29 without loss, the match was abandoned.
It was a similar story at Market Deeping who made 123 for four. Sleaford were 20 for one when rain stopped play for the day.
