A Gary Madine brace helped Sheffield Wednesday hammer Exeter to record a fifth straight home win.
The visitors almost took an early lead but Daniel Nardiello turned Matthew Whichelow's low cross just wide.
James O'Connor poked home his first of the season to give the Owls the advantage just before the break.
Madine then doubled the lead, heading in Ben Marshall's cross before grabbing his second from the penalty spot after he had been fouled by Danny Coles.
VIEWS FROM THE DRESSING ROOM
Sheffield Wednesday manager Gary Megson told BBC Radio Sheffield:
"I thought that was our best performance at home.
"Eventually the penny dropped, we started passing, getting the ball wide and once we got the first goal maybe Exeter's plan went out the window.
"Gary Madine has got a natural eye for the goal. He's got a talent for getting hold of the ball and he's now working a lot harder than he was, both in training and off the pitch, and he's getting his rewards for it."
Exeter City manager Paul Tisdale told BBC Radio Devon:
"Everything we know we're good at, we were good at today for 40 minutes. But we showed what we have to improve on as well.
"There's a fine line between a team where the players are driving forward on the fringe of confidence and them suddenly becoming confident.
"I can only do so much, I can only get that team on the field to start that way."
