Ben Cox admits it will be "massive" if Worcestershire can pull off a victory over Hampshire on the final day of the LV = County Championship match at the Ageas Bowl.

Worcestershire have dominated the opening three days, despite the loss of 101 overs to the weather, bowling out the home side for 222 and racing to 403-5 declared and claiming maximum batting points.

Hampshire, who were twice rescued by the elements in the two games between the sides last year, will resume on 1-0.

Keeper Cox, who scored a rapid 69 not out, told BBC Hereford-Worcester's Ian Randall, "The day coudn't have gone more to plan, we got 400 and pulled out and are all set to go tomorrow.

"We don't want to bat again. We want to bowl them out under our lead. Early wickets is our best chance of winning this game.

"That's all we can do, is put the ball in the right areas.

"There are definitely still balls doing something. Mitch (Daryl Mitchell) seemed to be on the receiving end of balls that were bouncing a lot and still seaming. It is just whether they nick it."

In terms of pulling off a potential victory, Cox admitted: "This is massive. We haven't been helped with the weather.

"It was the same last year and both games last year, Hampshire got away with games where we could have won both.

"Hopefully the weather stays clear and we get three sessions at them."

The in-form Cox shared an unbroken stand of 114 with Mitchell who followed up his 172 not out at the Ageas Bowl last summer with an unbeaten 142 – his first ton of 2015.

Cox said: "We had Daryl there the whole time and were able to bat around him.

"Colin Munro (34 off 32 balls) did so really well and it gave me that freedom to play my shots from ball one.

"I started off scratchy but it came off in the end."
