Jeremiah Stielow scored a game-high 17 points, and Anacortes stunned defending champion Lynden 52-44 on Friday in the Class 2A boys state semifinals.

The victory sends the Seahawks (22-5) into Saturday's championship game against Pullman.

Anacortes, which lost by double-figures to Lynden twice during the regular season, used an 18-7 run in the final quarter to push past the Lions. Anacortes trailed by as many as nine early in the second half.

A.J. Yost added 10 points and Billy King eight for the Seahawks. Stielow made 7 of 9 shots, including two of his three 3-point tries. Yost and Matt Aldridge also sank a pair of 3-pointers.

John Shine led Lynden with 14 points. After a strong first half, the Lions' shooting went cold after intermission. Lynden made just 15 percent (4 of 26) of its shots in the second-half.
