Cardiff Devils spoiled a landmark evening for Latvian goalie Ervins Mustukovs – and moved to within one win of clinching the Elite League title for a second successive season.
Devils powered into a 4-0 lead within 25 minutes and Mustukovs – nicknamed the Moose – was replaced by back-up netminder Brad Day.
This was a 200th Sheffield appearance for Mustukovs and he was hoping for a big night in Cardiff Bay.
But Devils, beaten 5-2 in Sheffield only four days ago, came out hard and powered to a 6-3 victory.
They can now clinch the League title in Northern Ireland on Friday when they play Belfast Giants – or on Sunday when Steelers visit Ice Arena Wales.
Netminder Ben Bowns and defenceman Mark Louis returned for Devils after injuries, while Tyson Strachan served a one-match suspension.
Drew Paris was the player to be rested, allowing Louis to play.
Two goals by man of the match Gleason Fournier led Devils to victory and put them on the verge of retaining their League title.
Fournier opened the scoring after 22 seconds as the Devils came out of the blocks quickly and Joey Haddad made it 2-0 with a powerplay goal after 18 minutes.
Haddad turned provider 23 seconds into the second period, combining with Fournier to set up Joey Martin just 23 seconds and when Andrew Hotham added a fourth goal after 24-57 and Cardiff were in control.
Steelers coach Paul Thompson took drastic action by withdrawing Mustukovs and sending out Huddersfield-born Brad Day to take over.
When Fournier took a delay of game penalty shortly after the Steelers were given the opportunity they needed and Mathieu Roy providing the finish.
A second power play goal from the Steelers 10 minutes later, scored by Ben O’Connor, threatened to break the game wide open, but the Devils replied with a powerplay goal of their own when Patrick Asselin fired past Day just eight seconds before the the second period break
Levi Nelson grabbed a third goal for the Steelers early in the third, but Fournier’s second of the night after 50-28 ensured Cardiff took both points.
There were two other matches played on Wednesday evening and head coach Adam Keefe returned to thrice. Giants were without Jim Vandermeer, Mark Garside, Jonathan Ferland, Dustin Johner and David Rutherford, but Keefe played and Belfast won 8-4 against Fife Flyers.
