Cole Aldrich had 12 points, 16 rebounds and blocked seven shots, helping No. 2 Kansas run over rival Missouri 84-65 Monday night.

Kansas (19-1, 5-0 Big 12) dominated inside and hounded Missouri defensively to turn the Border Showdown into a beatdown.

Marcus Morris scored 11 of his 17 points to help Kansas build a 20-point lead by halftime and twin brother Markieff Morris grabbed 11 rebounds for the Jayhawks, who haven’t lost to Missouri at home since 1999. Tyrel Reed was 4-for-4 from 3-point range in adding 14 points.

The Tigers (15-5, 3-2) needed a good shooting night to end a 10-game losing streak in Lawrence and didn’t get it. Missouri had trouble getting shots off inside against Aldrich and couldn’t hit from the outside, either, shooting 28 percent.
