The result was a defense-optional, end-to-end game that saw Timpview bury 14 3-pointers and let point guard Adam Santiago create off dribble penetration.
Hunter Erickson scored a game-high 21 points, and Adam Santiago and Nate Hanson each added 16 as the Thunderbirds (16-5, 10-2) kept their hopes of a Region 7 championship alive.
"It's a lot of fun," Erickson said. "Coach puts a lot of trust in us to go out there and play the way we play."
John Mitchell had 17 points and Blake Emery scored 11 of his career-high 16 points in the fourth quarter as Corner Canyon kept pace, but wasn't able to take a lead in the second half.
Timpview used a 9-0 run early in the third quarter to take a 53-43 lead, but the host Chargers (13-7, 6-6) rallied back behind Emery. The junior's 3-pointer with 1:01 to play cut the deficit to 71-69, but a pair of Santiago free throws and a Santiago steal and emphatic Erickson dunk ended the evening.
"We really focused on our rotations on defense," Erickson said. "Help your teammates out. … We were really good at it."
Jordan Sagers scored 15 points all on 3-pointers for Timpview, which is chasing Timpanogos for the region crown.
