An error, a walk and a hit batsmen led to three Husky runs, and the Cougs looking at a 5-4 deficit, in the decisive sixth inning.
Senior Patrick McGrath (pictured above) had two hits for Washington State, scored twice and drove in a run while Stefan Van Horn drove in a pair.
Washington State (17-29, 10-17 Pac-12) starter Scotty Sunitsch allowed three earned runs on six hits and struck out five in 5.1 innings. He left the game shortly after UW tied it at 4-4. Reliever Colby Nealy took the loss after allowing the go-ahead run in the sixth. The Huskies tacked on another run in the eighth on a WSU error.
The Cougars next head to Pasco to host a Tuesday night matchup against Gonzaga at 6:30 p.m.
