It marked Raspadori first Serie A start - and he crowned the game with a first goal.
"I'm breathless, it's the best day of my life," Raspadori told Sky Sport Italia.
“I want to thank the coach and the club for this opportunity, my family and girlfriend for always supporting me. Sassuolo are like a family and I will never regret joining this club.
“Kun Aguero is my reference and the player I try to emulate. I supported Inter as a kid, but as I've been at Sassuolo for 10 years, I am now a Neroverdi fan."
