Both Glamorgan and Sussex will be targeting victory on the final day of their County Championship clash.

The visitors are 331 behind with nine wickets standing so face a tough chase.

Sussex nightwatchman Aristides Karvelas said: “It was a very interesting day. I think we bowled well, as the ball gets softer it is harder to score, all in all will be interesting tomorrow so we will come here and look to win the game tomorrow.

“Sam Northeast batted very well too, we knew they would look to be more positive towards the end of the innings so we thought that would be harder if we kept the softer ball.

“I think the phrase is Night-hawk now for my role, there is a little bit of turn but not extraordinary turn so we need to have clear plans on how we are going to play against that.

“We can chase that down, we have spoken all season about playing positive cricket, so 100% we are coming here to stamp our authority tomorrow and look to win this game.”

Glamorgan centurion Northeast feels their spinners could be key on the final day.

He said: “It was a good day for us, a pitch where you have got to grind away and we are going to have to do that with the ball”

Northeast’s first century of the season put the hosts in a commanding position, setting Sussex a target of 359 in the final innings.

Glamorgan captain Kiran Carlson changed the tempo of the innings with his half century at faster than a run-a-ball, before leaving it to Northeast to finish the job with 104 and set things up for the final day.

The victory target is a tall order in 113 overs on a wicket that remains hard to score on.

Sussex finished on 27 for 1 after opener Tom Haines was caught at slip off Australian leg spinner Mitch Swepson. Sussex trail by 331.

Australian Nathan McAndrew was the pick of the Sussex bowlers, getting his second four-wicket haul of the match, while off spinner Jack Carlson toiled manfully through 28 overs for a return of 1-92 as the rest of the wickets were shared.

Glamorgan batted themselves into a strong position with a mixture of the tortoise and the hare.

Opener Zain-ul-Hassan provided the slow and steady part to set the platform for captain Carlson, who injected some pace into the batting by getting 59 off 50 balls.

Ul-Hassan added a mere 23 runs through the entire morning session as he progressed to 47 at the lunch interval, but even though it was slow it was also important with the Sussex bowlers finding a bit of hitherto unseen bounce in the Sophia Gardens wicket.

He lost opening partner Andrew Salter early, while number three Thomas Bevan departed for 15, Karvelas and McAndrew getting the wickets.

Ul-Hassan departed first ball after the interval to a shot of unusually aggressive intent against Carson, and at that point the game changed with Carlson walking to the wicket.

He immediately unveiled an array of shots, happy to go over the top and also employ the reverse sweep, clearly intent on ensuring Sussex would bat before the day was out.
