Top-scoring Lansdowne batsman Jamie Holmes said the target was "in the circumstances a really high total" to chase, considering a worn pitch at the end of the season, and the weather conditions.
Lansdowne batters scored 205 with the loss of six wickets and with eight balls to spare.
Opening batsman Holmes scored his 56 runs in 88 balls before being caught at cover by Greg Todd off a ball by Aaron Wilson.
Other high scorers were James Adamson with 44, and Matthew Stringfellow 45 not out.
Greg Todd bowled two wickets for 26 runs, and Aaron Wilson took two for 41.
