Batsman Jonny Bairstow said the late wicket of Jacques Kallis was reward for England's efforts on day three of the final Test against South Africa.
Steven Finn pinned Kallis lbw to leave the Proteas 145-3, 139 ahead, and the series hanging in the balance.
"To come away with that important wicket was fantastic," said Bairstow, who was bowled by Morne Morkel for 95.
“You look at little things you can improve on and I was pleased with how some of the things I implemented went”
"If we can get early wickets on Sunday and push on to bowl them out, we will look to chase down anything we're set."
He added: "We've got seven wickets to take in the morning and with the bowlers we've got, we should be confident of taking them."
Bairstow, recalled in place of
the dropped Kevin Pietersen,
helped rescue England from 54-4 on day two.
Although the Yorkshire right-hander missed out on a maiden Test ton,
England still managed to get up to 315 all out,
a first-innings lead of six.
"I was delighted to get 95," said the 22-year-old. "I was a bit disappointed not to get to 100, but I suppose it's only five runs.
"I came in on the back of scoring a hundred for England Lions, so I was feeling confident. I was just being myself."
Bairstow, playing only his fourth Test, struggled with short-pitched bowling against West Indies earlier in the summer.
"Bairstow showed he possesses the essentials for scoring runs in Test cricket. He was very disciplined, leaving the ball well and playing the shots he can. His chance will come again because that was a very encouraging innings"
But he came through a barrage from South Africa pair Morkel and Dale Steyn to register his highest Test score.
"When you get exploited in some sort of way, you go away and look at things but there are no drastic changes that I've made," he added.
"You look at little things you can improve on and I was pleased with how some of the things I implemented went."
Despite the Proteas losing Kallis late on, assistant coach Russell Domingo said South Africa, who will replace England at the top of the world rankings if they avoid defeat, were pleased with the position they are in.
"If someone said to us at the start of the tour we could be 1-0 up and in this position in the final Test then we'd have taken it," said Domingo.
"We're pretty happy with the position we're in at the moment, but we know there's a lot of hard work to do tomorrow."
