Northamptonshire had a tough day in the field as they continued their pre-season work at Nottinghamshire.
The hosts scored 312-1 from 60 overs with County trialist Ben Sanderson the only bowler to put a mark in the wickets column.
Play was eventually cut short by rain.
Four batsmen retired after getting runs as Greg Smith, Steven Mullaney, Samit Patel and James Taylor all notched put together half-centuries.
The reply saw Kyle Coetzer go for 19 but Alex Wakely (19no) and Rob Newton (0no) were unbeaten when the rain arrived at 42-1 from 10.1 overs.
