Jerome Randle scored 13 of his 17 points in the second half, and Patrick Christopher added 16 for the California Golden Bears.
"We made some mistakes. We made enough plays, but had too many turnovers," said Cal head coach Mike Montgomery. "We kept [Oregon] in the game in the first half. They are young. This league is for young players, and is not very forgiving. For us, we needed this."
California led 44-36 at halftime before scoring the first 10 points of the second half to pull away for its fourth straight win. The Bears had a 40-27 edge in rebounds and a 44-28 advantage on points in the paint as they won their fourth straight.
"We allowed our guys to catch the ball inside and finish," said Montgomery. "We got caught up in their tempo for a little while, but we are a good shooting team. Our big guys showed up a lot."
