COUNTY CHAMPIONSHIP DIVISION ONE, Hove:
16-19 June 2009 (Play begins 1100 BST)
CLOSE OF PLAY, DAY THREE: Somerset 367 and 178, Sussex 197 and 169-4 (Somerset 7pts, Sussex 3pts)
Chawla picked up 6-52 from 21.3 overs
A six-wicket haul from Piyush Chawla and an unbeaten century from Chris Nash gave Sussex hope of an unlikely win against Somerset on day three at Hove.
Beginning the day on 52-1, the visitors were dismissed for 178 thanks to Chawla (6-52) and Dwayne Smith (3-64).
The Indian finished with career-best match figures of 11-170 and has taken his total to 19 wickets in two games.
Set 349 to win, the hosts closed on 169-4, with Nash on a career-best 111, his first ton for three years.
After Mike Yardy and Murray Goodwin both fell cheaply, Nash shared 94 for the third-wicket with Ed Joyce (30) as Sussex looked to chase more than 348 for just the third time in their history.
But when Joyce was bowled off his pads by Peter Trego and Matt Prior was caught at short-leg off the bowling of Max Waller it was left to nightwatchman Jason Lewry to partner Nash to the close.
Earlier, Somerset lost their last nine wickets 126 runs in 39 overs.
Smith, who bowled 17 overs unchanged in the morning session, struck first by bowling James Hildreth.
Chawla then got to work by having Arul Suppiah caught behind by Prior with his second ball of the day.
He then had Zander de Bruyn caught at silly point, trapped Trego lbw and bowled Alfonso Thomas, Waller and Charl Willoughby to wrap up the innings.
However, it could be the last time he bowls in a Sussex shirt as his contract expires on 28 June and will only be extended if regular overseas player Yasir Arafat is selected for Pakistan's tour of Sri Lanka.
