With the score at 1-0 courtesy of Sam Surridge’s early penalty, the Glovers’ stopper made several fine saves to preserve the home side’s lead before Francois Zoko sealed victory in stoppage time.
Ex-Leicester City man Maddison has had to bide his time for his opportunity and boss Way was delighted with his display.
“The top teams normally have one goalkeeper who pulls off a world class save and he’s done that for us,” he said.
“I thought he was calm and assured when the ball was rolled back to him on a very difficult pitch.”
Way continued: “He’s worked extremely hard. We’ve had some uncomfortable conversations and I said to him he’d have to wait his time.
“He wanted to move in the window but this is his opportunity; you’re judged on your reputation and his reputation with the supporters singing his name is very high.
“I’m very pleased for Jonny and a mention must go to Steve (Phillips) as well because he’s worked extremely hard.”
