In a tight Carling Cup third round clash, the Danish stopper produced a fine second-hallf save to deny Roman Pavlyuchenko from distance, whilst Jonathan Waters squandered the Potters best chance whilst one-on-one with Heurelho Gomes in extra-time.
The deadlock could not be broken in 120 minutes though, ensuring the drama of a penalty shoot-out at the Britannia Stadium that often comes after a disappointing 0-0 draw.
Jermaine Pennant and Roman Pavlyuchenko both missed the target in the early stages from 12 yards, but after Ryan Shotton had made it 7-6 to the hosts, Sorensen denied Spurs debutant Massimo Luongo to win the game.
"It's nice to get the plaudits for the save, but it was the other lads who stepped up and put the ball into the back of the net. They had the real pressure, because as outfield players you are expected to score," he told the official Stoke website.
"We had chances in the first half and in the second half. Jon was unlucky in extra-time when it just rolled the wrong side of the post, but we got there in the end. We had to persevere, but we are in that draw on Saturday and that's all that matters now.
"For me to make that save was nice and I'm just delighted that we won the game. We played nearly two and a half hours of football and we never really looked in danger of losing the game at any point in my opinion."
The 35-year-old doesn't recall being on the losing side in the pressure-cooker situation of penalties during his 18-year career thus far, and is confident that should any other tie fall to a similar situation, he'd be able to repeat his heroics.
"I don't think I have lost a penalty shoot-out during my career and thankfully that remains to be the case. I feel confident when I'm between the sticks and if it came to it again in the next round then I would feel just the same," he concluded.
