AFTER completing a Specsavers County Championship double against Lancashire this week, Durham are aiming for a repeat in the NatWest T20 Blast this evening.

Although unbeaten at home, their only away win came in the second match at Old Trafford, where they won by six wickets with five overs to spare.

Lancashire are the defending champions yet find themselves bottom of the group needing every remaining result to go in their favour if they are to reach the quarter-finals.

That includes Warwickshire losing at home to leaders Nottinghamshire tonight, which would also help fourth-placed Durham, who now have Yorkshire breathing down their necks.

They remain narrowly ahead of their neighbours on run rate and it could work in their favour that their remaining games are at home to the bottom two clubs, Derbyshire being next Friday's visitors.

Durham have added Barry McCarthy to tonight's squad following his return from an impressive one-day international series for Ireland against Afghanistan.

He played in four of the five games and was Ireland's joint leading wicket-taker with Kevin O'Brien, earning ten wickets at 17.7.

Durham declined to risk Paul Collingwood in Wednesday's defeat at Headingley, but the need to win tonight could see him pressed back into action, along with Paul Coughlin.

New Zealander Martin Guptill scored almost half of Lancashire's runs in the Old Trafford clash, but is no longer available.

The dangerman is South African Alviro Petersen, who hit 103 not out at Leicester last Friday, only for the team to fall nine short of the Foxes' 207 for three.
