ESSEX plunged to their second home pre-season defeat in the space of a week as Kabir Ali's unbeaten 100 led Worcester-shire to victory at the Ford County Ground today.

The visitors passed Essex's first-day total of 179 in the 51st over of their innings.

The match was nicely poised when the visitors succumbed to an incisive spell from Graham Napier, who exploited the seamer friendly conditions to grab three wickets before lunch.

The 28-year-old took two in four balls as the visitors went to the interval on 103-7, with the bowler reflecting on analysis of 8-4-8-3 at that stage.

However, Ben Smith and Ali galvanised their side and gradually eased their way over the finishing line.

Smith relied on a studious approach while his partner punished the looser deliveries with abandon.

Essex will have been heartened by the form of Napier who spent time playing in New Zealand during the winter and extracted life and movement off the seam to the concern of a series of batsmen.

Resuming on their overnight 30-1, Worcestershire lost a wicket in the fourth over of the day when Daryl Mitchell drove at a ball from Maurice Chambers to give alert and tidy 18-year-old wicket-keeper Adam Wheater a catch.

Tony Palladino was another to impress in the morning session having Vikram Solanki caught at cover before moving the ball off the seam to pin Moeen Ali in front of his stumps.

Napier then made his favourable impression, knocking back the off stump of Steven Davies before moving the ball away from Gareth Batty to rattle his leg stump before a spectacular dismissal saw Gareth Andrew's off stump cart-wheeling out of the ground.

But the home side were unable to build on their supremacy as their opponents gradually and successfully addressed the early problems with a pragmatic application.

Smith reached his half-century from 112 deliveries that included 11 boundaries, while Kabir had raced to 41 from only 51 deliveries that embraced 8 boundaries by the time the winning run was struck.

Triallist and medium-pacer Alex Roberts bowled tidily although without a cutting edge and the county are expected to make a decision about his future with them imminently.

Worcestershire batted on, eventually reaching 299 for nine with Kabir on 100 not out when bad light brought a halt to proceedings with just over an hour of scheduled play remaining.
