The Golden Bears (2-1 overall, 0-1 PSAC) led 39-37 at halftime, and were ahead to start the second half. But a 57-55 advantage with 12:51 remaining was the last time KU found itself out in front.
The Vulcans (3-1, 1-0) turned it around and went ahead by as much as nine points twice in the second half, with the latest at 74-65 with 7:32 to go.
Kutztown would tie it at 76-76 with 3:10 left, and after the two teams traded baskets, California found
itself up 88-84 with 0:26remaining.
Two missed Vulcans free-throws gave the Maroon and Gold a chance to win it, but as the clock ticked under 0:10, a California steal sealed the deal.
Ridgeway’s 40 points in 39 minutes of action are the most points scored in a single game by a KU player since Stephen Dennis scored 42 points in Jan 2010.
Ridgeway went 10-for-10 at the free-throw line and finished with four assists and three steals.
Dan Cuevas tallied a double-double with 19 points and 10 rebounds. Anthony Lee also finished in double-figures in scoring with 13 points, and also had five rebounds and three steals.
Moe Williams had five points and six rebounds, and Josh Townsend grabbed six rebounds. Rafiq Marshall chipped in seven points.
California outrebounded KU 41-33.
Kutztown returns to the court tomorrow, Sunday, Nov. 19 with another PSAC matchup at Slippery Rock University at 3 p.m.
