Defending national champion Baylor maintained its top spot in The Associated Press men's college basketball poll, though not without ceding a No. 1 vote to Arizona, while the six remaining unbeatens continued their rise on Monday. The Bears ended a four-week streak of turnover atop the poll by taking care of Oregon last week, receiving 60 of 61 first-place votes from a national panel that regular covers college basketball. The Bears (10-0) reached the top spot last week after dominating then-No. 6 Villanova, something they never accomplished during their title-winning season.
