Geraint Jones said England would be going flat out for victory rather than settling for a draw on day five of the final Test against South Africa.
A safe draw would give England a 2-1 series lead, but Jones said: "Hopefully we can press home our advantage. We are aiming to win this series 3-1."
The wicket-keeper, who hit 50 off 54 balls on Monday, added: "The wicket is starting to go up and down.
"Andrew Flintoff ran in, hit the wicket hard and showed it had some gremlins."
Jones, who had had a quiet series with the bat, went on: "I've been working quite hard in the nets because I've not scored as many runs as I would have liked.
"I was happy to go out and score some today. I'm positive in both attack and defence - that's how I bat best."
Flintoff's wickets late in the day left South Africa still 53 runs behind with eight second innings wickets remaining.
Meanwhile, volatile South African paceman Andre Nel denied that he had gone overboard in sledging the England batsmen.
Nel launched regular outbursts during his six-wicket haul but said: "That is the way I play for my country.
"If I have the respect of my side in the changing room that is all I can ask for. It was good clean fun out there, I wasn't swearing."
The fast bowler was clinging to faint hopes that his team could conjure an unlikely final day win to square the series.
"There is still a small glimmer if we can somehow get 200 in front," he said. "We have to believe it."
