Matthew Potts promised England would continue to "throw punches" after an eventful opening day of the test series against New Zealand.
England lost the toss and were made to bowl first, but they looked to be in a commanding position when they dismissed the tourists for 132.
Sunderland-born Potts played a starring role on debut, taking four wickets for just 13 runs.
England then set out to try and build a large first-innings lead, and things started well as they reached 59 without the loss of a wicket.
As has happened all too often of late, though, England collapsed seemingly out of nowhere and finished the day on a disappointing 116 for seven.
It was a breathless day of Test cricket with 17 wickets flaling, but Potts urged people to keep on backing England.
"Yes, it was a rollercoaster," Potts reflected. "We've kind of had an eventful day, but we've come to entertain, that's our first and foremost thing.
"It's been an entertaining day of cricket and it's one that I've thoroughly enjoyed. We're still in a contest to win a game of Test cricket here so we're going to attack the next day.
"I think we're going to throw our punches. Personally I think it's very, very entertaining and I think it's what we all want to see.
"We want to exchange blows, and if they throw us two we'll throw them four."
Potts was England's best bowler on his first day as a Test cricketer, and he said he couldn't wait to get going since his initial call-up.
"I've ben chomping at the bit ready to go, I've been waiting to pull the top on and do the best job I can," he said.
"It was nice to get into it early and the wicket of Williamson really settled the nerves.
"I will wear that cap with pride every time I put it on. It's a proud moment for me and the family, a special day."
