Riley Hawken scored eight of his 16 points in the fourth quarter to help the Titans finish off the visiting Tigers in a Class 4A Greater St. Helens League semifinal game.
Union will host the district championship game, taking on Camas at 6 p.m. on Thursday. Battle Ground, which must now win twice to qualify for state, will play a loser-out game at 6 p.m. Thursday at Evergreen.
Union put away Battle Ground by outscoring the Tigers 19-11 in the fourth quarter. Titans coach Blake Conley said defense — particularly Micah Paulson’s work defending Nate Moring — was key to the strong finish.
Union led by five points after the first quarter, and took a six-point edge into the fourth period.
