The Spartans started out with a 4-0 lead with 6:50 to go in the first quarter.
Bonney Lake took the lead less than two minutes later and held on to the lead for most of the game.
Sumner led by one with 6:45 to play in the first half but that would be the last time the Spartans would lead the Panthers.
Bonney Lake led 31-22 at the half.
The Panthers led by as much as 12 in the fourth quarter. With the clock winding down, the Spartans weren’t able to catch up.
Bonney Lake’s coach Thomas Ostrander said he was very pleased with the team’s effort.
“Sumner is a very good team and we knew that going in,” he said. “We wanted to do our best to eliminate any easy scoring opportunities.”
Ostrander said Sumner did struggle shooting the ball but he also credits the Panthers’ efforts on defense for disrupting what Sumner is used to doing offensively.
Sumner’s coach Shane Patrick said he gives credit to Bonney Lake for executing its game plan.
“They played well and wanted the win more than we did,” Patrick said.
And after the end of the game, Johnson awarded a medal to freshman Payton Mitchell from Bonney Lake and freshman Joy Mahnken from Sumner for outstanding sportsmanship.
Sumner looks to take on Orting at 7 p.m. on Friday at Orting High School after the boys game ends.
