Dylan Guenther scored his playoff-leading 16th goal 7:47 into the third period as the Seattle Thunderbirds took a 4-2 win over the Winnipeg Ice and a commanding 3-1 series lead in the Western Hockey League championship on Wednesday.
Kevin Korchinski, Gracyn Sawchyn, with a goal and an assist, and Prince George native Nico Myatovic, with an empty-net goal with 7.4 seconds left, provided the rest of the offence for Seattle.
Game 5 is scheduled for Friday (7:05 p.m.) in Kent, Wash.
If the series is extended, Games 6 and 7 would be played in Winnipeg, Sunday and Monday.
All remaining games in the series will be televised nationally on TSN.
