The Idaho Steelheads were the highest-scoring team in the regular season.
Stockton goaltender Olivier Roy shut them down in the ECHL Western Conference Finals.
Roy stopped 44-of-45 shots as Stockton defeated Idaho 2-1 on Saturday night. The Thunder won the best-of-7 series 4-1 and advance to play Reading for the ECHL championship.
Steelheads forward Tyler Gron scored a little more than 4 minutes into the second period to even Game 5 at 1-1. Gron's goal was his team-leading eighth of the postseason.
Rookie Andrew Clark scored before the end of the period to put the Thunder up 2-1.
A desperate Idaho team outshot Stockton 13-4 in the third period, but Roy turned away everything the Steelheads threw at him, even after Idaho pulled goalie Josh Robinson.
It was hardly a surprise that the two teams played another close contest. The previous three games of the series were decided by one goal, and two of those contests went to overtime.
Robinson allowed two goals on 28 shots and finished with a 5-5-2 record in the postseason. Roy improved to 12-5-1.
For the series, Idaho outshot Stockton 191-155.
The series was a rematch of the 2010 conference finals. Idaho won that series 4-2.
