The Raiders knocked off Biola 25-23, 18-25, 25-22, 25-17 to open the day and then turned around and defeated Menlo 24-26, 25-16, 26-24, 25-22 to wrap up the tournament unbeaten.

Southern Oregon is now 6-1 in preseason play and opens Cascade Conference play next Friday at home against Warner Pacific.
