A second innings collapse saw Middlesex slump to an innings defeat against Sussex in the opening LV= County Championship match of the season at Hove.
Full scorecard (Cricinfo)
An excellent spell of bowling from Steve Magoffin, who picked up 5/56, saw Middlesex lose eight wickets for 33 runs as they subsided on the south coast.
Magoffin took the final wicket of Steven Finn to wrap up the victory before lunch, with the hosts triumphing by an innings and 127 runs.
Beginning the final day with nine wickets in hand and Dawid Malan and Chris Rogers well set at the crease, Middlesex would have had hopes of securing a draw.
And as Malan and Rogers (on the day he was named as one of Wisden's Five Cricketers of the Year) batted through the first 40 minutes without any troubles, the draw would have seemed achievable for the visitors.
However, when Rogers was removed for 41 by Jimmy Anyon, it triggered a dramatic collapse as the Sussex bowlers ran through a shell-shocked Middlesex middle-order.
Eight wickets fell in just 13 overs, with number eight James Harris (10) the only batsman to make it into double figures.
A late display of hitting from number eleven Finn (26) helped to save face, but Middlesex were eventually dismissed on the stroke of lunch for 154, handing Sussex a morale boosting victory to kick-start their campaign.
Middlesex will now face Nottinghamshire on Sunday 13 April at Lord's - the first game at the Home of Cricket this summer.
