Worcestershire 266 and 303 for 8 (Libby 65, Hose 64, D'Oliveira 51) lead Essex 404 by 165 runs

Fifties by Jake Libby, Brett D'Oliveira and Adam Hose ensured Worcestershire would make Essex bat again in their rollercoaster match at Chelmsford.

When bad light took the players off the field with 20 over remaining on day three of the Vitality County Championship match, Worcestershire had turned a 138-run first-innings deficit into a 165-run lead.

Libby laid the foundations for the recovery with a 112-ball 65 at the top of the order. But it was an 80-run stand for the sixth wicket between D'Oliveira (51 from 71 balls) and Hose (64 off 91) - the pair coming together with two runs still required to erase the arrears - that gave Worcestershire hope of securing a third successive victory to move clear of the relegation area.

Simon Harmer spearheaded the mercurial Essex attack, sending down 26 overs in the foreshortened day and taking 3 for 110, including the wicket of Hose to an extraordinary delivery. Essex will be looking for a first victory in four games on the final day to maintain their fading interest in the title race.

Nightwatchman Joe Leach lasted just four balls on a grey, overcast morning before Sam Cook ended his 21-ball nought by inducing a thick edge through to the wicketkeeper. Gareth Roderick narrowly avoided a pair before he was turned around by Jamie Porter on six and nicked to second slip.

Libby found good support from Kashif Ali in a 51-run third-wicket stand until Paul Walter was introduced and with his fourth ball had Ali following the ball across him through to slip.

Libby survived a couple of scares but reached his fifty from the 90th ball faced, his eighth four helped on its way high over the wicketkeeper's head. His latest partner Rob Jones took a liking to Harmer, hitting four successive boundaries, two of them identical shots on the sweep.

However, the 55-run fourth-wicket stand was broken soon after lunch when Libby drove loosely at Cook and was caught low down at backward point. And six runs later, Jones went for another sweep against Harmer, this time more uppishly, and Dean Elgar completed the dismissal when running back from square leg.

That left Worcestershire five down and still two runs short of making Essex bat again. That landmark was duly achieved and built on as Hose and D'Oliveira dug in obdurately initially to the extent that Porter came on for three overs and went off again without conceding a run. The first fifty of their partnership took 16 overs.

The run-rate rose steeply with 31 runs added by the pair in the next four overs before Matt Critchley switched ends to give Harmer a rest and first ball had D'Oliveira fencing to second slip. Harmer's rest spanned the tea break but his first ball after the interval brought the downfall of Hose, who padded up outside off-stump to a ball that turned prodigiously as it hit the crease to leave him bewildered to see the bails lying on the ground behind him.

Harmer had a third wicket to his name when Ethan Brookes went to reverse-sweep, as he had successfully on several occasions in the first innings This time, however, the ball popped up off an edge to Robin Das diving full-length at short leg to cling on one-handed.

With the floodlights on and the light deteriorating appreciably, Essex declined the option of taking the new-ball when it was due after 80 over, sticking with their spinners. The gesture proved in vain as the umpires deemed it too dark to continue an over later.
