LAWRENCE, Kan. -- Kansas junior guard Wayne Selden struggled to rediscover his shooting form of early January, when he established a career-high scoring total in the Big 12/SEC Challenge.

After netting 33 points in an overtime win against Kentucky, Selden failed to score in double figures over four consecutive games while shooting 9-for-28 from the field.

On Monday, however, he snapped out of his funk, scoring 18 points and hitting four 3-pointers as the No. 2 Jayhawks stomped Oklahoma State 94-67 in Allen Fieldhouse.

The victory pushed Kansas (22-4, 10-3 Big 12) into a half-game lead in the conference over West Virginia, which plays at Texas on Tuesday.

"It felt good to see the ball go in," Selden said. "My teammates keep telling me to do that, so I'm going to continue to shoot."

The Jayhawks still relied on scoring balance. Five other scorers, including each of the starters, cracked double figures. Junior forward Landen Lucas recorded the second double-double of his career with 14 points and a game-high 10 rebounds, leading a 45-27 advantage for Kansas on the glass.

Junior guard Frank Mason added 14 points and six assists for the Jayhawks. Senior forward Perry Ellis had 15 points, junior guard Brannen Greene 11 and sophomore guard Devonte' Graham 10. Kansas won its sixth in a row despite digging a quick 8-0 deficit and trailing by as many as nine in the first half.

"We came out sluggish," Selden said. "It's all about changing it, and we were able to change it."

Actually, Kansas did so in both halves. A 13-0 run in the first half contributed to a 47-34 halftime Jayhawks lead, which included a 3-point bomb by Greene at the buzzer.

Then in the second half, the Jayhawks used a string of 10 unanswered points after the Cowboys closed within 62-56. Selden and Greene each canned 3-pointers during that surge.

The Jayhawks were coming off an emotional win at Oklahoma two days earlier in a battle of Big 12 leaders.

"I thought we played a little tired," Kansas coach Bill Self said. "Our guys, I thought tonight they had an inner confidence, which is good, and we'd be OK the whole game. But I don't think we had the intensity level we had in Norman."

That was reflected in the eight turnovers the Jayhawks forced, a number Self insisted should be better at home. Kansas still managed to made 32 of 64 shots while recording the most points Oklahoma State has surrendered on the season.

Senior guard Jeff Newberry, the only player to start every game for Oklahoma State, led the Cowboys with 19 points. Sophomore guards Jeffrey Carroll and Tavarius Shine added 13 and 11 points, respectively, as Oklahoma State (12-14, 3-10) remained winless on the road in Big 12 play.

Cowboys sophomore guard Tyree Griffin landed awkwardly under the hoop and twisted an ankle late in the first half, but he demanded that Oklahoma State coach Travis Ford use him in the second half with the team already short-handed. Griffin managed a career-best 12 assists.

"He's a guy you want in your fox hole. He's a tough little sucker," Ford said.

Oklahoma State was playing without guard Jawun Evans, a key contributor in the first matchup with Kansas, which the Cowboys won by 19 points.

"We're a little bit of the walking wounded right now. It's almost beyond belief," Ford said. "We had some absolute warriors. These guys were really banged up. They gave it a go, so I'm proud of that. We had some fight to us at times, just not enough."

Selden canned two 3-pointers during the Jayhawks' 13-point first-half run and hit a free throw for a four-point play with 2:36 remaining. Selden led the Jayhawks with nine first-half points. Lucas added eight points and six rebounds, while Graham had eight points.
