Cameron Cranston scored on a drive in the lane with 1.5 second left to lift Union in the Fitz Showcase at Lewis & Clark High School in Spokane.
Kai Gamble had two big offensive rebounds in the final minute to give the Titans a chance to win it.
The basket was only Cranston’s second of the game.
“He was in foul trouble the whole night,” Union coach Blake Conley said. “I think four points is his lowest point total in a couple of years.”
But Union got contributions all around to get the win. Keithen Shepard had 13 points and seven rebounds from the guard position. Tyler Combs had 14 points, including a key 3-pointer in the fourth quarter. Jason Franklin Jr. also had a big 3-pointer in the fourth.
