Freiston remain winless in the East Lindsey League after a century from Stuart Barker led Louth to victory at the Danny Flear Centre.
Bowling first, Ollie Booth had William Allis caught behind for six and Richard Paul saw Laurence Scott stumped for 22.
However, Barker (100), supported by Richard Bell (32) and Matthew Elston (41 not out) took Louth to 233-5.
Booth did bowl Bell, while Graham Kirtley claimed two wickets.
Freiston were never really in the hunt as Richard Paul made 35 and Darren Tate struck his way to 25, but wickets fell regularly.
Clubs veterans Mick Warrington (nine) and Graham Kirtley (15 not out) showed good application but they finished short, all out on 130
