SAN ANTONIO (AP) -  The 20-year wait is over.  Kansas has captured its first men's basketball championship since 1988 by outlasting Memphis 75-68 in overtime.

Mario Chalmers extended the game by draining an off-balance three-pointer with 2.1 seconds left in regulation before the Jayhawks scored the first six points of OT.

The Jayhawks trailed 60-51 after Robert Dozier hit a pair of free throws with just over two minutes left in regulation.

Chalmers was named the most outstanding player of the Final Four after finishing with 18 points.

Darrell Arthur paced Kansas with 20 points and 10 rebounds.

Derrick Rose added 18 points, including nine straight for Memphis during a 12-2 spurt that put the Tigers ahead 55-49.

It's the third national championship for Kansas.
