PART-time off spinner Chris Nash claimed career-best figures to help Sussex secure an opening County Championship win over Glamorgan by 201 runs on the final day at the Swalec Stadium.

With Glamorgan offering some stubborn resistance from Ben Wright (57) and James Allenby (62), Nash was brought into the attack and suddenly hastened the Welsh county’s demise.

He took two wickets from his first three balls and ended with figures of four for 12 from 9.3 overs.

Sussex, who took 21 points from the contest to Glamorgan’s three, wrapped up victory 35 minutes before tea with 39 overs remaining.

Glamorgan had resumed on 51 for one in their second innings, chasing an improbable 405 to win, and it took until only the seventh over for Corey Collymore to break through and have Michael Powell lbw.

And 61 for four became 65 for five three overs later when nightwatchman Dean Cosker also went lbw - the 14th such dismissal in the match - to Luke Wright.

But Sussex’s march to victory was held up for 30 overs either side of lunch as Wright and Allenby put up some impressive resistance.

The sixth wicket added 113 runs with Wright reaching a positive half-century from 73 balls on the stroke of lunch.

And with skipper Michael Yardy unable to get the breakthrough from his frontline attack, he turned to Nash.

It proved to be an inspired bowling change as Nash broke the sixth-wicket pair immediately. First he had Wright caught at slip after the ball had deflected off the wicketkeeper’s gloves, and two balls later Mark Wallace chopped onto his stumps as Glamorgan went from 178 for five to 178 for seven.

Amid the carnage Allenby survived at the other end to follow Wright to a half-century, which included eight fours, from 92 balls.

But Allenby was again a helpless witness as Nash struck in his seventh over to have James Harris caught behind, before he himself fell victim to Monty Panesar who had him snaffled at short leg.

Nash wrapped up the victory in the 84th over by having Chris Ashling caught behind.
