Jarred Hyder's 3-pointer broke a tie with 1:33 remaining and Owen Koonce scored a career-high 30 points to help visiting Cal Poly stun Stanford 97-90 in a nonconference game Saturday night. Isaac Jessup knocked down five 3-pointers and finished with a career-high 21 points, helping the Mustangs (5-4), who have won five of their past seven games. Maxime Raynaud had a team-high 21 points for Stanford (6-2), but failed to record a double-double for the first time this season. He finished with a season-low five rebounds. The Cardinal led by as many as 13 points in the first half and 12 early in the second before Cal Poly chipped away.
