A furious finish earned the Hawks second place in the Class 2A Greater St. Helens League.
Hockinson finished the game on an 8-0 run, getting four free throws from Sydnie Cole in the final six seconds.
As the second-place team, Hockinson (9-11, 5-3) will host a district playoff game on Friday, probably against Black Hills of Tumwater.
Ridgefield led by six points with 1:49 remaining. Cole made a steal and was fouled with 5.4 seconds remaining, hitting both free throws to tie the score.
