Point guard Frank Mason III, like most in attendance for Kansas University’s 67-57 win over Oklahoma State Tuesday night at Allen Fieldhouse, left the game impressed with a vicious one-handed dunk by freshman forward Cliff Alexander in the first half.

“That was extreme. I thought he was just going to do a regular, old jump-hook, but he didn’t. It was extreme,” Mason said.

Minutes: Brannen Greene, who played three minutes the first half, did not play in the second half. He was removed after not going after a rebound hard and did not return. Self said it was coach’s decision. Svi Mykhailiuk did not play (coach’s decision).

This, that: Mason extended his double-digit scoring streak to 13-straight games. KU’s longest double-digit scoring streak a year ago belonged to Andrew Wiggins (eight games). … Devonté Graham has recorded nine assists without a turnover in 40 combined minutes over the last two games. … KU is 3-0 to start Big 12 play for the ninth-straight season and the 11th time under Self. … KU leads the all-time series against OSU, 110-55. KU is 45-9 vs. OSU in Allen. OSU set a KU season opponent-high with 29 fouls, surpassing the previous season-high of 28 by Tennessee on Nov. 28. The Cowboys’ 29 fouls were most by a KU opponent since Texas committed 31 personal fouls on Feb. 1, 2014. … KU held OSU to 16 field goals (31.4 percent) and three made three-point field goals, evening out to an 18.8 three-point percentage, while only giving up four offensive rebounds. All of these totals are Kansas opponent season lows. … The last time KU was assessed with multiple technical fouls in a game came on Nov. 28, 2013 in a loss to Villanova (team technical and another on Andrew White III). … The last time Kansas had two individual players assessed with a technical foul in a single game occurred when Brady Morningstar and Thomas Robinson drew one apiece in a 78-63 victory over Cal on Dec. 22, 2010.
