Frank Mason III had 16 points and nine rebounds, Kelly Oubre Jr. added 14 points and ninth-ranked Kansas beat No. 24 Oklahoma State 67-57 on Tuesday night to remain perfect in the Big 12.
The Jayhawks (14-2) moved to 3-0 in league play for the ninth straight year largely thanks to its ability to get to the foul line. Kansas was 32 of 46 on free throws while attempting just 43 field goals in a game made choppy by the abundance of whistles.
Oklahoma State (12-4, 2-2) was still within 61-55 with 1:48 remaining, but Mason made two of his nine free throws and Devonte' Graham added two more moments later to put the game away.
Le'Bryan Nash scored all but two of his 21 points in the second half to lead the Cowboys.
