Sheffield Wednesday secured a valuable 1-0 win in their bid to beat the drop in the Championship by seeing off neighbours Rotherham.
Ike Ugbo's sixth goal in five games proved to be the difference between the two sides, leaving the Owls three points from safety.
Defeat casts Rotherham a whopping 19 points adrift of safety at the bottom.
Wednesday had more than enough chances to put the game to bed in a dominant first half but did not take the lead until past the hour mark and then had to defend sternly to keep hold of the three points.
Viktor Johansson had an early save to make after Ian Poveda had skipped by Shane Ferguson and rolled the ball into Liam Palmer whose effort was palmed out.
It took a tremendous block from Cameron Humphreys to deny Ugbo the opener after Anthony Musaba had cut in from the left flank menacingly.
Will Vaulks then almost caught out Johansson with a free-kick he shaped to cross before shooting low. The Sweden international was able to just get across to tip it wide.
Wednesday thought they had gone in front but Akin Famewo's header from Vaulks' free-kick was ruled out for offside.
Poveda then cut in from the right wing and flashed a powerful effort just wide of the far post.
Wednesday continued to be on top in the run-up to the break and Musaba's effort was deflected onto the roof of the net after he had been slipped in by Poveda.
Rotherham started the second half brighter and had Wednesday keeper James Beadle worried for the first time when Sam Nombe took aim from distance and saw his effort go just over the bar.
Wednesday finally took the lead in the 66th minute with a well-worked move.
Barry Bannan and Ugbo were involved with neat passes in the box and the latter was then on hand to stroke home from Dominic Iorfa's cross.
A dangerous free-kick saw Rotherham threaten with Jordan Hugill getting a touch onto fellow substitute Cafu's powerful effort to divert the ball just off target.
Wednesday then had talisman Bannan to thank for preserving their lead as he somehow outstretched a leg to deny Andy Rinomhota's goal-bound effort.
Marvin Johnson lashed at a big chance to double the advantage in the closing stages and his shot was well off target.
Mallik Wilks could have also put the game to bed in stoppage time but his diving header from Johnson's cross cannoned off the post.
