|Close of play, day three: Somerset 213 & 235 v Sussex 177 & 218-1|
|Somerset 4pts, Sussex 3pts|
Chris Nash and Ed Joyce shared an opening stand of 201 as Sussex closed in on victory over Somerset at Hove.
Set 272 to win, the hosts reached the close 54 short of victory on 218-1, with Nash still there on 111 after Joyce fell for 84.
Somerset had begun day three on 114-1, with Marcus Trescothick 64 not out.
But once he fell for 79, Rana Naved-ul-Hasan took 5-82, to complete a 10-wicket match haul, and James Anyon 3-39 as Somerset were dismissed for 235.
Nash, who had passed 50 six times already this season, enjoyed a belated present a day after his 28th birthday as he finally converted a half century into the 10th hundred of his career.
His partnership with Joyce was their sixth century stand of the season.
Naved, who also had a hand in the run-out of Gemaal Hussain with a direct hit, took 10 wickets in a match for the second time in his five seasons with Sussex.
CLOSE OF PLAY SUMMARY
BBC Sussex's John Barnett:
"A masterful century from Chris Nash leaves Sussex on the verge of an amazing victory, a feat they at one point looked like achieving inside three days.
"That they were not chasing more was down to a great comeback led by their seamer.
Rana Naved snaring his second five-wicket haul to finish with match figures of 10-161, well backed by James Anyon."
