Middlesex condemned Sussex to their first defeat of the County Championship season thanks to a 10-wicket win.
The visitors needed just 80 minutes on the final day to wrap up victory after as Sussex were dismissed for 310 in their second innings and the Middlesex openers knocked off their target of 44 in nine overs at Hove.
Sussex led by just 21 runs overnight with Luke Wright on 151 but Middlesex made inroads as soon as they took the second new ball.
Tim Murtagh's first delivery with it made the breakthrough when Chris Jordan (two) edged a lifter to wicketkeeper John Simpson.
Sussex lost their eighth wicket in the next over when Steve Magoffin wafted outside off stump on nought and Simpson again did the honours to reward Corey Collymore's excellent line.
James Anyon briefly gave Wright some support as the ninth wicket pair added a further 15 but Murtagh struck again with the score on 308 when Anyon was caught behind off another ball which lifted sharply off a length to give Simpson his eighth catch of the game.
With only last man Monty Panesar for company, Wright tried to hit out but only succeeded in finding Neil Dexter on the long off boundary, having added ten runs to his overnight score. Wright's 161 came off 185 balls with 24 boundaries and a six.
Murtagh and Collymore both picked up three wickets while Steve Finn, deemed surplus to requirements by England at Lord's, was not required to bowl.
Middlesex needed 44 to seal their fourth win of the season and Dawid Malan finished unbeaten on 19 and Sam Robson, whose first-innings 166 had done so much to set up their victory, was 18 not out.
