Mason Oberg scored 21 points as the Titans stayed alive in the 4A bi-district tournament at Tacoma’s Stadium High School.
Union (15-6) will face either Todd Beamer or Kentwood in a winner-to-state game Thursday in Tacoma.
Oberg made all four of her free throws in the fourth quarter, helping the Titans hold the lead. Mackenzie Lewis scored 15 points, including three of Union’s eight 3-pointers. Oberg also had three 3-pointers.
“This was our third bus ride to Tacoma in six days,” Union coach Mike Cranston said. “They showed a lot of resiliency. I’m really proud of them.”
