The game was abandoned, but Wanneroo could boast good performances from opener Alex Burton, who top scored with 35, and wicketkeeper Colin Smith, who contributed an undefeated 29.
The bowling was strengthened by the return of Gary Atkinson, and while he and Jack Catterall bent their backs in anticipation, the weather was the winner.

Mt Lawley was 1-36 at the close of play.
