Last season’s first grade runners-up side enjoyed a fine team performance, with plenty of contributions in the six-wicket win.
Gosnells won the toss and chose to bowl at Sutherlands Park and this paid off, reducing the away side to 4-59 early.
Matt Hanna was the chief destroyer with 3-28, well supported by former Lincolnshire player Aaron Onyon (2-25).
Chasing Mt Lawley’s total of 181, the home side cruised with Tim Hale, Luis Reece and Darcy Short all hitting half-centuries.
