The Treasure Valley (14-22) built an early edge on Saturday, but the Spokane (21-13) roared back to steal a 5-4 victory at Spokane Falls Community College.
The Spokane took the lead in the ninth inning on an RBI double by Erika Hall.
Madilyn Naccarato racked up two RBIs on three hits for the Spokane. He singled in the second and fifth innings.
The Spokane got the win thanks in large part to Michele Strauss's dominant, eight-strikeout performance. Strauss allowed four earned runs on six hits and nine walks over nine innings.
The Treasure Valley were led by Debbie Henze's hitting. Henze went 1-4, drove in one and scored one run. He homered in the second inning.
Bailee Mills was charged with his eleventh loss of the year. He lasted just 8 1/3 innings, walked six, struck out three, and allowed five runs.
