John Naff went 3 for 3 and had a tiebreaking home run in the eighth inning as Washington rallied to beat California 4-2 Friday night in Berkeley, Calif.
The blast made a winner out of Alex Nesbitt (4-2) and helped lift the Pac-12-leading Huskies (24-14, 10-6) to their season-high fifth consecutive win.
The game was turned over to closer Troy Rallings in the eighth inning and he recorded the final six outs, including striking out two Cal (23-15, 9-10) batters in the ninth to earn his Pac-12-leading 13th save.
The Seattle Thunderbirds will play the Brandon Wheat Kings in the best-of-seven Western Hockey League championship series.
