LUKE WELLS is urging a big final day effort as Sussex bid to force an unlikely win against Glamorgan.

Marnus Labuschagne scored his third century of the season as the visitors continued their fightback on a rain-shortened third day at Hove.

Only 21 overs were possible before rain arrived but Glamorgan progressed from 137-1 to 218-1 in their second innings – still 16 behind – with Labuschagne 131 not out.

Glamorgan will be confident of avoiding defeat but batsman Wells insists Sussex’s hopes of victory should not be written off if they can rattle through the visitors’ batting.

Wells said: “We have to give it everything tomorrow to try and get some early wickets and then who knows?

“With the firepower in our top order we would back ourselves to score quickly at a good rate and chase a target.

“If we have a fast run chase we’ll definitely be going for it.”

Sussex skipper Ben Brown used six different bowlers in the an attempt to force a breakthrough but with no joy.

Wells added: “It tends to be the way at Hove and around the country at the moment that once the balls gets a bit softer it loses its zip and there isn’t much sideways movement either.

“I thought we bowled very well on the first day but since then we’ve thrown a lot at them and, to be fair, Labuschagne and (Nick) Selman have played pretty well.”
