In the afternoon game, the Zags lost 10-3, forcing a winner-take-all game this evening.
Gonzaga will hope they are given an at-large bid to the NCAA Tournament as they dropped game two of the doubleheader by a score of 16-3.
The Zags sent senior RHP Sam Hellinger to the mound for his first career start.
Hellinger was able to make it through the first inning unscathed, allowing just one hit.
The Zags staked him a one run lead to start the second inning after Justin Jacobs singled up the middle and scored Sam Brown.
The Cougars then strung together five straight hits to start the bottom of the frame.
