WACO – Kansas freshman Marcus Morris had a dominating start after halftime and twin brother Markieff had some big contributions of his own and the 21st-ranked Jayhawks beat Baylor 75-65 Monday night for their seventh straight victory.

Kansas (18-4, 7-0), which moved into the Top 25 on Monday for the first time since early December, didn’t lead until Sherron Collins had a pair of short floaters in the final 43 seconds of the first half to make it 30-28.

Marcus Morris then scored the Jayhawks’ first eight points after halftime. When Markieff Morris hit an open 3-pointer from the top of the key with 15:56 left, the Jayhawks led 43-33.

Collins had 16 points, and has led Kansas in scoring in all but five games this season. Marcus Morris had a season-high 13 points and Mario Little had 12.

Henry Dugat and Kevin Rogers had 15 points each to lead four players in double figures for Baylor (15-7, 3-5), which has lost four straight games.
