Columbia High came within two points of a 2-0 lead over Ilwaco during last Saturday's Trico Division match in Miller Memorial Gym.
But the Fishermen rallied from a 23-19 deficit to win the second set and even the match. They followed up with 25-15, 25-23 victories in the next two sets to spoil the Bruins' bid for their first league win.
Columbia got off to a hot start before cooling off, leading by as many as eight points in the first set before holding on for a 25-22 decision.
Junior Corrine Blankenship served back-to-back aces to clinch the win.
Junior Abby Zuck had two kills for the Bruins in the first set, and junior Whitney Shelley and senior Krista Bakke each had a kill and a scoring block.
In the second set, the Bruins got rolling again, riding the serving of junior Megan Harvey (2 aces) to a 7-2 lead.
Ilwaco rallied to tie the score at 10 and then 11 before Columbia opened up a six-point spread at 18-12, then 19-13.
But the Bruins couldn't shake the Fishermen, who scored three kills and a service ace down the stretch to pull out a 25-23 win.
Ilwaco jumped on CHS early in the third set and quickly led 13-3. The Bruins finally got their attack going again, however, and closed to within 14-7 on a pair of kills from senior Emily Swick.
That was as close as they got, though.
The fourth set saw eight ties and eight lead changes as Columbia and Ilwaco battled for momentum. CHS's last lead of the set, at 8-7, came on a kill by Swick.
Ilwaco took control after that, building a 19-14 lead at one point before CHS made another run.
A kill by senior Jessica Mosbrucker made it 24-22. Ilwaco then misplayed a serve by Shelley that cut its lead to one.
The Fishermen hung on, however, when the Bruins hit the ball into the net.
At Columbia High 3, Hockinson 2 --
The Bruins avenged a season-opening loss to the Hawks with a come-from-behind, non-league victory here last Thursday.
Columbia hammered out a 29-27 verdict in the first set but couldn't put Hockinson away in the second.
The Hawks rallied from a 17-13 deficit and took its first lead since 10-9 at 18-17, on a kill that deflected off a CHS block. They finished off their 25-22 victory with an ace.
Hockinson capitalized on CHS errors in the third set to build a 16-3 lead en route to a 25-13 triumph.
Columbia, sparked by senior Krista Bakke's 6 kills and 2 service aces, led from start to finish in the fourth set to win 25-21 and force a fifth and deciding game.
The Bruins never trailed in the tiebreaker, either. Senior Jessica Mosbrucker registered 3 kills and finished off the Hawks with a service ace on match point.
