The England scrum-half has been locked in a battle for possession of the No 9 jersey so far this season with new Welsh recruit Dwayne Peel.
But for last weekend's EDF Energy Cup clash against Cardiff Blues, Wiggy was asked to help provide the attacking inspiration for a young back-line by playing at fly-half.
And though Sale lost the game 18-17 in heartbreaking fashion, Wiggy came through with flying colours.
So much so, that Sharks head coach Kingsley Jones revealed the 25-year-old could even have a long-term role in the position.
"He had a fantastic game and I've always thought that Richard can play at fly-half. It's not just a cover thing. He can go forward playing in that position if he wants to," said Jones.
"He showed against Cardiff he's got such good feet, especially when they used their rush defence.
"We were really pleased with him. His kicking game is good enough, his understanding of the game and the way he runs is fantastic, so he's a serious option for us at 10."
Challenge
Prior to Saturday, it had been a stop-start season for the Blackpool-born star with both he and Peel being rotated between games.
It's a situation that could easily have vexed a man who was England's first-choice scrum-half during this year's Six Nations.
But Jones hailed Wigglesworth's positive reaction to the challenge of vying with Peel.
"It's been OK so far. He's not over the moon but then neither of them are," said Jones.
"In regards to his competition with Dwayne, it's strange. In these situations, you either love each other or you hate each other and these two seem to be best mates. There's a lot of mutual respect there."
Philippe Saint-Andre was equally effusive about the England star's impact at 10.
"We all know that Wiggy is a quality player but I wanted to see him at fly-half," said the Edgeley Park director of rugby.
"He made maybe one mistake in the entire game and he showed a lot of class."
Do you think Wigglesworth has a future at 10? Have your say.
