Reece Topley has set his sights on a one-day whitewash in South Africa ahead of the third ODI at Centurion.
England are in control in the five-match series after victory in the opening two instalments, having already won the Test series 2-1.
A win on Tuesday would see England become the first touring side for 14 years to beat South Africa in both a Test and ODI series.
After posting bowling figures of 4-50 in the five-wicket triumph at Port Elizabeth on Saturday, Topley wants England to keep their feet firmly on the gas.
"We don't want them to get back in the series," Topley said. "We're one game away from the series, and we want to wrap it up here - and then hope we can go for a 5-0.
"We have backed up the Test series win brilliantly. Two series wins out of two going into the World Twenty20 would be an amazing feat for us.
"We're in such a brilliant place at the minute. We're all just enjoying ourselves, and having a lot of fun doing what we love.
"I'm thankful I'm still playing for England, and I don't want the ride to end. I'm living my dream by putting in performances for England, which is where everyone wants to be."
Topley is still in the early stages of his international career but is hopeful of securing a place in England's World T20 squad ahead of next month's tournament in India.
"For me personally, I've definitely left no stone unturned," he added. "I'm looking forward to finding out what the squad is.
"If I go to India, it will be a dream come true because that's where I want to be, representing my nation at a World Cup.
"If I'm picked to play out there I would love to show what I can do and show what skills I have on that stage."
South Africa, meanwhile, look set to bolster their backroom staff with the addition of the the recently retired Neil McKenzie as batting consultant - the former Proteas batsman confirming the appointment on Monday.
Discussing McKenzie's expected arrival, Hashim Amla commented: "I'd be happy with that, Neil was one of the names in the hat from what I hear. I played a lot with Neil, and I have very good memories of that.
"He was an excellent batter, great cricketing brain. If he's the guy who's joining us, that would be fantastic. I'm sure he would be [pleased] as well, to be part of the South African team again."
