Marshall Moses matched his career high with 18 points and provided a much-needed inside threat as Oklahoma State held off scrappy Iowa State 81-67 on Wednesday night in the first round of the Big 12 Conference tournament.

Craig Brackins had 23 points and 12 rebounds for his 15th double-double of the season for Iowa State which finished the season at 15-17. The Cyclones haven’t won a Big 12 tournament game since 2005.
