Jason Gillespie has no arguments with the efforts his players are putting into their Championship campaign.

But he would rather not see them five wickets down with not enough runs on the board over the next four days.

Sussex host Glamorgan at the 1st Central County Ground from today (11am) as they aim for a second win of their Specsavers County Championship division two campaign.

Gillespie has named an unchanged 13-man squad after last week’s draw at Northamptonshire.

Whether it will also be an unchanged XI remains to be seen as Sussex look to bolster their top-order batting and spice up their seam attack.

Luke Wells, Stiaan van Zyl, Chris Jordan, Ben Brown and Phil Salt have all treated supporters to some super innings in the last two four-dayers.

But the trend at the top of the order is one head coach Gillespie cannot ignore.

Ever since a torrid first hour of the season, when they slumped to 36-5 at home to Leicestershire. Sussex have struggled for a first-innings platform.

Having lost that match, they dug out a win at Durham despite being 71-7 in their first innings.

They were 68-6 on the first day at Wantage Road before recovering in some style.

Gillespie said: “The lads’ efforts on the last day at Northampton were excellent.

“I thought we bowled pretty decently as a unit and Mir Hamza was top class.

“In the end, the pitch didn’t break up enough for us to force victory and credit must go to Adam Rossington and Ben Hutton for their resistance.

“We know we have areas to improve on including making sure we are not finding ourselves around 100-5 as often, but it was good to see three batsmen score hundreds this week. That is definitely something to build on.”

In fact, that reference to 100-5 is being kind. The fifth wicket in their three first innings has fallen at 36, 49 and 68.

Laurie Evans, who did not play last week, remains in the 13 with Harry Finch and Tom Haines thought to be the most at risk.

With the ball, Jared Warner will hope for a first outing since signing on loan from Yorkshire. Hamza was a massive threat at Wantage Road but his fellow seamers did not pose the same problems.

Sussex skipper Brown said: “I felt we weren’t on it as a group with the ball at Northampton and we didn’t give him enough support.

“Mir swung the ball enough to cause them problems, he was the most likely threat.

“We’re a bit disappointed because we tried everything but ultimately our skill with the ball wasn’t quite there and the other bowlers didn’t group enough balls in the right areas like Hamza did to get us the result.”

Brown found form with the bat after a troubled start to the season with his 156 in the first innings, sharing a stand of 309 with Jordan (166).

But he has had to go out into tough situations this season – and last year at times.

He said: “Being 68-6 on the first day was not good enough.

“We have to play the moving ball better. We just can’t get rolled over every time the ball does a bit.

“There were some good performances but there are areas to improve.”

Members of Glamorgan’s young side have great memories of Hove after their run-chase in the Royal London One-Day Cup recently.

Daniel Douthwaite, a big player that day and a century-maker at the ground for Cardiff MCCU last month, took six wickets last week as Glamorgan won a thriller by two wickets at Derbyshire.

Glamorgan showed batting strength in depth in that one, scoring almost 600 runs across the two innings with a top individual score of 75 by opener Charlie Hemphrey.

Sussex: from Brown, Briggs, Evans, Finch, Haines, Hamza, Jordan, Sakande, Salt, van Zyl, Warner, Wells, Wiese.
