Nando Eggenberger put away the eventual winner late in the second period as the Oshawa Generals held off the Niagara IceDogs 3-2 on Monday to win their Ontario Hockey League playoff series.
Oshawa won the best-of-seven series 4-2 and will face the Ottawa 67's in the OHL's Eastern Conference final.
Brandon Saigeon and Giovanni Vallati also scored for the Generals, while Kyle Keyser made 34 saves for the victory in net.
Ivan Lodnia had both goals for the IceDogs and goalie Stephen Dhillon stopped 27 shots.
Oshawa was 2 for 5 on the power play and Niagara could not score on its one-man advantage.
The 67's have seen plenty of their division rivals in Oshawa this season, as the two played each other eight times. Ottawa took the season series, winning five of their meetings, and the three that they lost were all by a single goal.
Game 1 of the OHL Eastern Conference Final will be played at The Arena at TD Place at 7 p.m., April 18.
Game 2 is set for Saturday, April 20, at 2 p.m.
