If Barnsley are going to suffer after boss Lee Johnson quit for Bristol City last week - they didn't show it. They began life without him with an emphatic victory over Bury for their seventh straight League One win.
The Tykes, who Johnson left for Bristol City on Saturday, were ahead early on with Marley Watkins' great solo goal.
Sam Winnall sweetly struck his 17th of the season for the hosts after clever work from Conor Hourihane.
Adam Hammill finished Ashley Fletcher's centre for 3-0 before Leon Clarke shot wide when one-on-one for Bury, managed by ex-Tykes boss David Flitcroft.
Barnsley had Johnson's former assistant Tommy Wright and coach Paul Heckingbottom in temporary charge.
Having reached the Johnstone's Paint Trophy final with victory over Fleetwood on Thursday, they moved up to 10th and are now five points off the play-offs, while Bury stay 15th.
Barnsley joint-caretaker boss Paul Heckingbottom told BBC Radio Sheffield:
"We tried to stress that Thursday had gone and it was important to focus on this game in terms of application, momentum and getting their minds right in what was another big game.
"We were a little bit sluggish at times, especially first half, but again it shows if your mind's right, you're OK as we got stronger as the game went on.
"It's been a hectic week, but to be honest it's probably better that way because you get everything over and done with in a few days.
"We've managed to get the result which is great so now we just move forwards and carry on as normal."
Meanwhile, Johnson watching from the stands saw his Bristol City side win a vital relegation six pointer at Charlton who now prop up the Championship after Bolton and Rotherham drew.
