Durham head coach Geoff Cook has said batsman Michael Richardson boosted his first team prospects with a vital knock in the draw at Somerset.
Richardson, 26, has only played 13 matches since his first-class debut in 2010, but racked up 70 runs to arrest a middle-order collapse at Taunton.
"When it comes to pushing your own game forward, he couldn't have done more," Cook told BBC Newcastle.
"He did a brilliant job when the game was in the balance."
Cook added; "We could have lost wickets, had a huge deficit and been facing a tricky last day ourselves.
"As it was he helped Paul Collingwood put on 100-plus which got the emphasis in our favour, so he did a brilliant job."
Warwickshire provide the next opposition for Cook's side on Wednesday, with memories fresh from the 318-run defeat at Edgbaston earlier in the campaign.
Despite failing to polish off Somerset over the four days, results have picked up markedly - two defeats in nine games in all competitions - to push the north east club up the table.
"There's some fairly deep confidence in the team now which is lovely to witness," Cook added.
"They deserve it, they've fought hard in every game they've come across."
