They took just five points from their trip to Boston, but second-bottom Alford’s defeat to Bourne left the gap between the two teams at 36 points with just one match to play.
After losing the toss and fielding first, Tom Cuthbert was in the thick of things early on, running out opener Peter Mitchell for five and then trapping the remaining opener Sam Holland lbw for 19.
But from 54-2 came the partnership which decided the match as Ishan Jayarathna and Jonathan Cheer put on a massive 211 for the third wicket.
Cheer blasted six sixes in his 151-ball innings of 137 before finally succumbing to the spin of Xander Pitchers.
The Namibian also removed Jayarathna for an even faster-paced 87, off 74 balls, while Cuthbert (3 for 60) took two late wickets as the home side posted a daunting 293-6 from their 50 overs.
Louth’s reply started badly when captain Laurence Scott departed for two, but Paul Martin shared stands of 44 and 41 with John Medler (12) and Pitchers (22) to take the visitors past the 100 mark with three wickets down.
But when Martin went soon after for 55, Louth’s hopes took a nosedive.
Richard Bell (15) and Seb Darke (28) added 48 for the fifth wicket to give the visitors some hope, but Louth lost their final six wickets for 29 runs to collapse to 180 all out and a 113-run defeat.
They stay 10th, but could yet finish as high as sixth with victory in their final game at home to Alford on Saturday (noon).
* Alford and District CC suffered a four-wicket defeat at home to Bourne on Saturday, despite a defiant batting show from Andrew White and Rikki Bovey.

Bourne reached 189-6 in the 40th over to ensure victory.
Bradley McGilloway (2 for 14) and Nick Bennett (2 for 30) led the way with the ball, while Steve Kirkham and Bovey both claimed wickets.
Alford will finish second-bottom of the county’s top flight.
