Lansdown edged their way over the winning line by three wickets against Weston-super-Mare.
After winning the toss and choosing to bat, visiting Weston were grateful for the efforts of Shabil Ahmed (61) and Jamie Howson (51) as their team-mates struggled to get to grips with the bowlers.
There were also two run-outs as Weston were dismissed for 199, with three-fors for both Jordan Price and Thomas Hankins.
Joe Jenkins lost his wicket early for Lansdown, but Jordan Smith steadied the ship at the top with a solid 52.
The middle order of Hankins (28), Brandon Allen (33) and Reece Croker (32) all turned in steady scores as Lansdown closed in on their target, but it was left to Jackson Hamilton (4no) and Price (13no) to finish the job.
