|County Championship Division One, Uxbridge|
|Close, day one: Middlesex 98, Nottinghamshire 114-4|
|Middlesex 0pts, Notts 3pts|
England captain Andrew Strauss hit a half-century for Middlesex, but it was not enough to prevent Nottinghamshire taking control.
Strauss (50) and Gareth Berg (32) were the only two players to make double figures, while five were dismissed for ducks, in a total of 98 all out.
Andre Adams took his season's tally to 46 wickets with figures of 6-32.
Notts closed on 114-4 - a lead of 16 runs - with Michael Lumb unbeaten on 35 and Adam Voges eight not out.
The visitors lost Alex Hales for 14 to Corey Collymore and reached 38-1 at tea, and were three down by the time they had a first-innings lead.
Riki Wessels made 34 before being caught behind by John Simpson off Berg, while Samit Patel, who was part of England's one-day lost his wicket to Tim Murtagh for 18, of which 16 came off one Toby Roland-Jones over.
Murtagh (2-28) also picked up the wicket of England Lions captain James Taylor for three and shortly afterwards bad light and rain brought an end to the day's play.
A wet outfield delayed play until 11:45 BST and, on a damp and cloudy morning, the toss was crucial - Middlesex lost the flip of the coin for the eighth time in nine matches.
Notts skipper Chris Read put the home side into bat and opening pair Harry Gurney (2-23) and Ben Phillips (1-20) took full advantage to reduce them to 24-3.
Adams struck in successive balls in his opening over - first having Dawid Malan caught at slip by Hales and then bowling Simpson for a golden duck.
Berg and Strauss, who had not played at all since England's a month ago, stopped the rot and put on 63 for the sixth wicket in 19.3 overs either side of lunch.
But Adams removed Strauss, who will lead England in the first Test against South Africa next week, a ball after he had reached his half-century with a delivery that angled in and hit the top of off stump.
Middlesex collapsed again as Adams took four for none in 10 deliveries to complete his fourth five-wicket haul of the season.
VIEW FROM THE COMMENTARY BOX
BBC London 94.9's Kevin Hand:
"Nottinghamshire bowled, fielded and batted the better of the two teams on the opening day on a pitch that is offering enough to keep the bowlers interested and the batsmen on their toes.
"Strauss played well as the wickets tumbled for his 50, but fell to a jaffer from Adams. Berg dug in for his 32 before trying to hit out in the second of Middlesex's collapses.
"Middlesex's bowlers came close to replicating the accuracy and consistency of their opposite numbers, but the visiting batsman were quick to recognise that patience and application are vital on this track."
