Dominic Calvert-Lewin thanked his pal Tom Davies for giving him the opportunity to score his first Premier League goal for Everton.
Davies raced onto an incisive through pass from Ross Barkley and put the ball on a plate for the forward to open his account for the Toffees.
Calvert-Lewin’s eighth-minute strike set the ball rolling for a sixth successive Goodison league win.
Everton are now up to sixth in the Premier League table, leapfrogging Manchester United who play Middlesbrough on Sunday.
“The goal was set up by my good mate Davo,” Calvert-Lewin beamed. “You couldn’t have wrote it better. He’s got down the line - I’ve seen he’s put the ball in and I’ve tried to get to the far post. It’s missed a few players and it fell to me. I couldn’t have wished for a better opportunity.
“I didn’t really know what I was doing on the celebration! I’m just over the moon.”
Calvert-Lewin had already exited the action before Everton dispatched the Tigers with three late goals.
Enner Valencia netted 69 seconds after stepping off the bench and Romelu Lukaku completed the scoring with an injury-time double.
“It was tough in parts,” Calvert-Lewin acknowledged. “Hull obviously got a man sent off but Enner has come on and changed the game. That put the comfort there and Big Rom at the end scored two well-deserved goals. His record speaks for itself.
“Our home form has been really good this season and we look to continue it every time we play at Goodison. I think the fans have got a big part to play in that and they help us every game. They drive us forward and push us on.
“When it was 1-0 the fans urged us forward. It does help and it’s a big reason why we are so good at home.”
