Match ends, Rochdale 0, Sheffield Wednesday 2.
Sheffield Wednesday edged past League One Rochdale to reach the third round of the Carabao Cup.
The Championship side took the lead after the break when Elias Kachunga headed home Liam Palmer's cross.
Oliver Rathbone went close for the hosts before Josh Windass wrapped it up with a powerful effort.
The Owls, who made 11 changes from the team that beat Cardiff on Saturday, will face third tier Ipswich or Premier League side Fulham in the third round.
Rochdale boss Brian Barry-Murphy:
"I thought the lads were brilliant and worked incredibly hard at a time when it's very difficult for us when we are physically playing catch up.
"We performed very well in the first round at Huddersfield and then we were poor at Swindon in the league on Saturday, but we've bounced back tonight with a fully committed display against a very good side.
"I was conscious of not getting distracted by the loss at Swindon and just concentrate on the amount of work the lads are putting in and to try to make sure we came through this game with everyone unscathed."
Sheffield Wednesday boss Garry Monk:
"I made 11 changes but apart from a couple they were all first-team players, it's a first-team squad so in terms of changes I had no worries.
"I had to be very mindful of the energy we used on Saturday and the fact it was important to get minutes into these players because the squad is going to be needed.
"It was an excellent performance overall. I like Rochdale and the way they play and we knew they would test our shape. We set out to press them and I felt when we stepped it up in the second half our fitness levels really started to show with the goals and the chances we created.
"This is only our fifth week back, normally this would be pre-season so it was the first 90 minutes for a lot of the lads but the energy and fitness showed through."
