MARK Wood proved his fitness for the Test series against South Africa by taking 5-54 before rain halted the second day's play in Durham's Specsavers County Championship match at home to Worcestershire.

The paceman took the visitors' final two wickets with the new pink ball but not before they had established a lead of 170.

Brett D'Oliveira completed his century and Moeen Ali made 58 in Worcestershire's total of 367.

Wood had already taken three of the wickets when Worcestershire resumed on 213-4.

He completed his haul by knocking out Ed Barnard's off stump with his seventh delivery with the new ball before forcing last man Josh Tongue to fend a catch to short leg.

There were four wickets for off-spinner Ryan Pringle who found himself under attack, conceding 73 in 12 overs.

In gloomy conditions with the floodlights again on from the 2pm start runs came briskly as Moeen played in carefree style.

When Durham posted a short extra cover he chipped Chris Rushworth over the fielder but was fortunate as two inside edges took him to 50 off 59 balls.

D'Oliveira, who resumed on 91, drove Rushworth for three through extra cover to complete his 159-ball century with 15 fours and a six.

He then top-edged Ben Stokes' second ball of the day over the wicketkeeper for another boundary.

Stokes finished with 0-80.

When Pringle was introduced D'Oliveira hit him for four to mid-wicket then lifted a no-ball over long-on for six – counting eight – before whacking a full toss straight to cover to depart for 122.

Following the stand of 130 Moeen swiftly followed, missing a sweep in Pringle's next over to fall lbw.

Three wickets had gone down for six runs when George Rhodes sat back to cut and edged to wicketkeeper Stuart Poynter.

Ross Whiteley was on one when he drove Pringle for a straight six as he and Ben Cox stopped the rot with a stand of 73.

In Pringle's final over before the new ball was due Whiteley tried to heave him over mid-wicket and was bowled for 43.

Wood did the rest, leaving Cox unbeaten on 32.

Worcestershire skipper Joe Leach said: “It was an outstanding innings by Brett and all credit to the other batsmen for getting us in a strong position.

“We had the perfect situation with a lead of 170 and a new pink ball to bowl with under the lights so it's a pity we didn't get back out there.”
