County Championship D1, Old Trafford, day four: Lancashire 450-6 dec. beat Sussex 251 & 180 (f-o) by an innings and 19 runs
Lancashire broke Sussex's resistance on the final day
Points: Lancashire 22, Sussex 4
Sussex squandered their chance to wrap up the championship as Lancashire kept their slim title hopes alive with an emphatic win.
Lancashire will go into their final match against Notts on Wednesday with an outside chance of snatching the title.
But Sussex, who only needed a draw in this match to secure their first ever title, will still be crowned champions if they can manage six points from their match against Leicestershire.
IN THE EVENT OF A TIE
If Sussex and Lancashire finish equal on points, Sussex will be crowned champions by virtue of winning more games
It became a mathematical impossibility for reigning champions Surrey to win again when Sussex gained two batting points in their first innings.
Gary Keedy, who grabbed a five-wicket haul in the first innings, repeated the feat second time around to finish with match figures of 10-167.
Sussex's third wicket added 40 runs to the overnight score of 21-2 before skipper Chris Adams fell to John Wood for 35, starting a slide that saw four wickets fall for 35 runs.
It was left to first-innings centurion Murray Goodwin, carrying stitches after being struck on the eye by a Peter Martin bouncer on Friday, to dig deep.
Goodwin used up 119 balls in reaching 57 but his resistance was broken when Keedy trapped him leg before to reduce Sussex to 146-8.
Mark Davis stubbornly saw off 89 balls for his 11, but Sussex were beaten when Keedy had him caught just before tea.

Sussex: CJ Adams, TR Ambrose, PA Cottey, MJG Davis, MW Goodwin, JD Lewry, RSC Martin-Jenkins, RR Montgomerie, Mushtaq Ahmed, MJ Prior, BV Taylor.
