The Steelers will now look to host the third and final round of the competition for European clubs when it is staged for January 12-14.
Having suffered a harsh 7-1 defeat on the opening day against eventual group winners Yunost Minsk on Friday in the Danish town of Rungsted, the Steelers regrouped and came up big by following up a 5-4 win after a shoot-out against the hosts on Saturday with a second triumph just 16 hours or so later to seal the second qualification spot in the final group standings.
Both teams went into Sunday's encounter knowing the winner would progress along with Minsk and it was a case of role reversal for the Steelers when, for the first time in the competition, they found themselves in front
Handed a five-minute powerplay after Riga forward Martins Cuplins received a boarding penalty plus a game misconduct, Jonas Westerling put Paul Thompson's determined side ahead at 11.18. However, the lead lasted barely a minute with Gatis Gricinskis replying with a shorthanded effort for the Latvians.
But with time still remaining on the initial powerplay, Tim Wallace and John Armstrong combined to set up Mathieu Roy to score from close range at 13.42. They weren't finished there either, with Levi Nelson - the recipient of the heavy hit from Cuplins - setting up linemate Andreas Valdix to fire home at 14.41, just nine seconds before the powerplay ended.
But, in what was proving a chaotic six-minute spell, Scott Aarssen incurred a slashing penalty to hand Riga a powerplay goal of their own at 16.22 from the stick of Martins Gipters.
There was no way the flurry of scoring could be maintained by two sides desperate to make the final round and so it proved with the second period being a tense, goalless session. It meant Kurbads had to come out and throw everything at a disciplined Steelers side in the third.
Late penalties against Andre Deveaux and Levi Nelson combined with Kurbads pulling netminder Uldis Calpa meant there were some anxious moments in the closing minutes for Thompson's team. but, as with the previous night, Ervins Mustukovs was in stand out form in the Steelers goal, with Ben O’Connor's empty net strike with just four seconds remaining enabling a collective sigh of relief all round for the South Yorkshire club and their loyal band of followers.
