Freiston, Leake and Leverton claimed victory over Boston Cricket Club’s Third XI - with Darren Tate the star of the show.
The right hander top scored with 36 before taking four valuable wickets with his inswing bowling as the away side recorded a 97-run victory.
Batting first, FLL opener Zeeshan Saeed made 23 while Stewart Kirtley added 26.
Martin Hodgson made an attractive 34, but Freiston were indebted to a superb 51-run partnership for the seventh wicket between Tate and Charles Lenton.
Tate struck six fours on his way to 36 and Lenton looked busy at the crease as he made an unbeaten 35.
Lenton struck a boundary in the final over as Freiston posted 201-9 in this South Lincs and Border League Division Two match.
For Boston, Steve Appleyard took three wickets, with Tom Appleyard and Kevin Brooks taking two each.
In reply, Boston’s Herbert Ushewokunze made 19 before he was run out by Tate and Ollie Booth then quickly dismissed Jack Tetther, caught behind by Kirtley.
Sean Barnett and opener Karl Pick took the score to 90-2, before Pick was trapped LBW by Sean Burns for a well-made 44.
That wicket brought about a collapse as Boston subsided to 104 all out.
Tate claimed four wickets, including Barnett for 14.
A second wicket for Burns preceded a superb run out by Saeed, while a super diving catch by Tommy Atkinson saw Booth claim his second wicket as Boston were dismissed in the 31st over.
