The high-school-basketball postseason is on. Chief Sealth International High School‘s boys-varsity team played a loser-out game against Ingraham tonight – a team they had handily defeated in the regular season, and beat again tonight, 74-49. L.J. Burns led Sealth scoring with 18 points, followed by Hafid Yassin with 15. Tomorrow night, coach Colin Slingsby‘s Seahawk boys play at Lakeside, 7 pm.
