Sheffield experienced a tough night as they slumped to a heavy 67-27 defeat against Premier League high-flyers Edinburgh at Armdale.
The Tigers had raced to a superb 52-40 win over Workington at Owlerton on Thursday to give their confidence a major boost.
However, they were unable to add to their points tally on a tough night against the star-studded Monarchs.
It was always set to be a tough ask for Joe Screen’s side, and their job became even harder as they slipped six behind early on.
They fought back to keep the deficit reduced to just eight points after five races to keep their slim hopes of a consolation point alive.
But Edinburgh raced to back to back 5-1s in heats six and seven to truly seize control.
The Tigers duly placed at tactical ride on youngster Josh Bates - and when he hit the front alongside partner Taylor Poole the visitors looked set for a huge 8-1 to catapult themselves back into contention.
Unfortunately for them, Justin Sedgmen had other ideas as he spectacularly snatched victory to deny the Tigers a much-needed heat advantage.
Having seen Simon Stead miss out on victory with their second attempt at double points shortly afterwards, they conceded six 5-1s in the final seven races as the were condemned to a crushing defeat.
Skipper Stead fought admirably from the No.1 spot, racing to Sheffield’s only race win in heat five.
However, the Tigers ultimately had no answer to a powerhouse Edinburgh side on a night they would rather forget.
