NORMAN, Okla. — With six days to prepare for a team that has struggled all season on the road, Oklahoma turned Saturday’s home game against Kansas State into a confidence booster heading into the final four games of the Big 12 season.Buddy Hield scored 18 points and Isaiah Cousins added 17 to help Oklahoma beat Kansas State 86-73 and begin to clear up the Big 12 standings with four games remaining in league play.“I was really, really happy for our guys. I thought they opened the game sharp on both ends of the floor and attacked offensively,” Oklahoma coach Lon Kruger said.The runaway win helped break a three-way tie for third with Oklahoma, Kansas State and Iowa State all entering the day with 8-5 league marks. Iowa State’s 71-60 Saturday win over TCU kept the Cyclones knotted with the Sooners.Second-year Wildcats coach Bruce Weber saw his freshman class combine to score a season-high 43 points but there were few Wildcat positives in this one.“We just kind of let them do what they wanted and they got going and we spotted them too many points to ever make it a game,” Weber said.Oklahoma (20-7, 9-5) dominated in nearly every category, leading by as many as 27 points in the second half.The Sooners took their first lead 3 minutes in when Hield drained a 3-pointer following a Kansas State turnover.
