"(We were able to) get a stop and get a real good road win," first-year Kansas State coach Bruce Weber said.

The Wildcats made just 37.5 percent (21-of-56) of their field goals, and the Sooners hit just 38.8 percent (21-of-49).
"There's much work left," Kruger said of rebuilding the Sooners. "Absolutely. We'll learn from today.
"We've got to cut harder. They're physical and strong and their hands are on you all the time. We've got to get separation and cut harder. We realized today we've got a long way to go. (The team has) done a great job and made a lot of progress. They'll keep working at it." Will Spradling led Kansas State with 12 points. Senior forward Romero Osby scored 13 to lead Oklahoma.
"Since I got here, they talked about Oklahoma got them twice last year," Weber said. "So they were able to get them back this year."
The Wildcats held the Sooners scoreless for almost 11 minutes between the first and second halves.
"Sometimes you can realize it, but you can't really dwell on it," Osby said of scoring drought. "We'd get a stop and go at them again. A lot of shots didn't fall."
The Wildcats also had a dry period during the same time, with six straight empty possessions, but they ended it with 1:41 left in the first half with a basket from Omari Lawrence, then added a layup about 30 seconds later from Rodriguez.
Kansas State's Martavious Irving drained a wide-open three and led the Wildcats with a team-high eight points into halftime.
The Wildcats scored the first basket of the game with a dunk from Jordan Henriquez. From there, the Wildcats went 12 of 28 on field goals and 4 of 10 from three-point range, including two threes from Irving.
"I told them we just want to stay up in the standings," Weber said. "The only way to do that is win. Win on the road and not let an opportunity pass us by."
The Sooners were led by M'Baye, who scored seven points on 3-of-6 shooting.
