Lytham continued their fine run of league form over the weekend, as they inflicted Ormskirk's first defeat of the season.
Captain Jimmy Wisniewski and Richard Openshaw led the way, taking four wickets each, as Ormskirk were restricted to 132 all out.
Lytham reached their target with two tickets to spare, with Wisniewski making 29, and Rob Dingle and Nick Knight 25 each.
But the Fylde coast side suffered defeat on Sunday in the Lancashire Cup, suffering a 79-run defeat at BAE Preston.
Maunsey was the star turn for the home side, scoring 116 in a total of 243-4. Lytham could only reach 164-9 in response, with Martin Hibbert scoring 40.
