Pakistan spin wizard Mushtaq Ahmed ripped through Hampshire with 7-64 to inspire Sussex to a 94-run victory.
The wily veteran ended a defiant stand of 67 between Michael Carberry and Dominic Thorneley, as the home side slid from 144-3 to 211 all out.
Earlier, Sussex lost skipper Chris Adams, who did not add to his overnight 31, but Robin Martin-Jenkins ensured they would set a tough target of 306.
The all-rounder struck a commanding 91 before he was caught by Carberry.
