No. 6 Kansas 97, Iowa State 89 (OT): Freshman Ben McLemore banked in the game-tying 3-pointer with one second remaining in regulation and finished with a career-high 33 points, and the host Jayhawks pulled away from the Cyclones in overtime to win their 22nd straight conference opener.

McLemore hit all six of his 3-point attempts as Kansas (13-1, 1-0 Big 12) received double-doubles from Jeff Withey and Kevin Young to extend the nation’s second-longest home winning streak to 31 games.

Melvin Ejim had 19 points and 11 rebounds to lead Iowa State (10-4, 0-1).

The Cyclones were on the verge of winning in Allen Fieldhouse for the first time since 2005 as Ejim answered a jumper from McLemore with one of his own to give Iowa State a four-point lead with 26 seconds remaining in regulation. But Elijah Johnson scored the next three points to trim the deficit to 77-76 and, following a pair of free throws by Korie Lucious, McLemore brought the home crowd to its feet with his game-saving shot.

Taking advantage of the disheartened Cyclones, McLemore drained his sixth and final 3-point attempt nine seconds into overtime as the Jayhawks scored the first 11 points. McLemore added a layup for good measure with 1:03 left to stretch the lead to 95-81.
