"It's been so good to have 'Quinny'," said Van der Dussen.
"He has a determination about him that I haven't seen in a very long time. He's ploughing back into the team in all aspects, in the bowling meetings, in the batting meetings, being one of our senior guys."Van der Dussen added: "The guys really feed off him. He's one of my favourite guys to bat with. He really guided me through my innings today. At times I was under pressure and I was asking him about a few options.
"He's such a cool and calm guy out there, thinks so clearly. It was just great to bat with him. But he's been brilliant in the last few weeks."
