Steven Mullaney's unbeaten 88 helped Nottinghamshire reach 161/2 before rain and bad light ended proceedings early on day one of their LV= County Championship fixture with Middlesex.
Mullaney was almost run out in the first over, but his patient approach paid dividends after Middlesex captain Chris Rogers had inserted the opposition on a cloudy morning.
The right-hander struck ten fours in an innings which occupied 193 balls.
The opener lost partner Riki Wessels - promoted up the order after Alex Hales was left out of the team - to Neil Dexter for 14 with the score on 43, but it was the only casualty on a morning where Middlesex's attack largely failed to threaten.
Michael Lumb, in stark contrast to his efforts in England's t20 side earlier this month, was even more circumspect than Mullaney as they put on a partnership of 113 for the second wicket.
Lumb fell late in the day to in-form, off-spinner Ollie Rayner, but Middlesex's chance to put pressure on new batsman James Taylor was scuppered by first bad light, then rain, forcing the abandonment before 5pm.
