Spirit River led on the scoreboard 2-1 following the first, and added to that lead in the second, scoring two unanswered for a 4-1 score entering the final frame.
It was a high intensity game in Spirit River, as both teams wracked up over 36 minutes of penalties, with Fort. St. John going 3-for-8 with the man-advantage, while on the other end of the ice, the Rangers managed to go 3-for-9.
Todd Alexander scored one power-play marker, as well as an even strength goal, while Clayton Bahm scored once and chipped in with two assists, Luke Middleton scored a goal on the power play, while adding an assist, and both Girard Dicaire and Jeff Shipton each found the back of the net once.
It was a busy night in net for Senior Flyers goaltender Jared Andersen, who got a serious workout, facing 40 shots Saturday night.
Despite the loss, the Senior Flyers have still won the previous 8-of-11 meetings between the two clubs.
The Senior Flyers will have to use this loss as motivation, as the two teams will meet again December 1 in Fort St. John, for game two of the home-and-home series between the Senior Flyers and the Rangers.
