Middlesex seamer Toby Roland-Jones took 3/28 as Middlesex struggled on day one of their LV = County Champion match with Warwickshire at Edgbaston.
On his recall to the side, following Middlesex's historic victory against Yorkshire at Lord's earlier in the week, the 26-year-old was the pick of the bowlers as fourteen wickets fell, removing three of Warwickshire's top four to leave the home side 123/4 at close, trailing Middlesex by 44 runs.
Earlier in the day Middlesex had slumped to 167 all out from 43.5 overs, having at one stage been 66/8.
A late cameo with the bat from Steven Finn - who struck 37 not out - and Roland-Jones (25) helped Middlesex rally to a semi-respectable total. The duo put on 61 for the tenth wicket.
Chris Wright finished with 4/56, while Keith Barker (1/61), Oliver Hannon-Dalby (2/10), Richard Jones (2/27) and spinner Jeetan Patel (1/9) shared the rest of the wickets between them - as loose shots cost the majority of Panthers' batsmen their wickets.
Captain Chris Rogers (34) and Ollie Rayner (31) were the only recognised batsmen to register double figures in a middle order that was missing Eoin Morgan, who is on England duty.
Bears debutant Sam Hain top scored with 42 for the hosts, before he was bowled by Roland-Jones - the same method of dismissal he got all three of his wickets with.
Part-time bowler Neil Dexter took the other Warwickshire wicket to fall, as Ian Westwood edged one to Rayner at slip.
Ateeq Javid (27no) and Tim Ambrose (13no) will resume on day two as the Bears look to make the most of their bright start.
