LAWRENCE, Kan. (AP) _ Rex Walters scored 10 straight points during a decisive stretch of the second half Monday night, vaulting No. 3 Kansas past No. 12 Oklahoma State 77-64 for at least a share of its second straight Big Eight title.

The Jayhawks (22-3, 10-2) handed the Cowboys (22-6, 6-6) their fifth straight Big Eight road loss and their 28th loss in 30 trips to Allen Fieldhouse, where Kansas has won 16 straight conference games.

Oklahoma State's Byron Houston, who scored 26 points, slipped the ball inside to Randy Davis for his second straight slam dunk. That pulled the Cowboys to 60-56 with a little more than five minutes left after Kansas had dominated much of the game.

But Steve Woodberry answered with a 12-footer, then Walters drove in for another layup and a 64-56 lead with 3:03 remaining, sparking a 14-4 surge that wrapped up the game.

The Cowboys, who tied Kansas for last year's title and began the season with a Big Eight-record 20 straight victories, were eliminated from the race. Kansas has won or shared 40 conference titles.

Walters wound up with 18 points. Adonis Jordan had 14, Eric Pauley 13 and Richard Scott 10.

Cornell Hatcher had nine points for Oklahoma State, whose point guard Sean Sutton was held to a season-low 1 point.

Kansas went ahead by 12 early in the first half, but Houston, last year's co-winner of the Big Eight player of the year award, sparked a run that brought the Cowboys to 48-46 with 9:58 remaining.

Three times Oklahoma State sliced the margin to two points, but the Cowboys never regained the lead. Walters, who sat out last season after transferring from Northwestern, rebounded a Houston miss and drove the length of the floor for a layup, beginning his 10-point surge. A few minutes later he stole an Oklahoma State pass and again drove in for a layup.

Two more Walters baskets were followed by a pair of free throws, then Walters fed Woodberry inside for a layup and a 58-51 lead with 6:04 to go.

Kansas, a 64-56 loser at Oklahoma State in January, out-rebounded the Cowboys 25-8 in the first half but managed only a 36-29 halftime lead because of a big discrepancy in turnovers and free throws. Oklahoma State hit eight of 11 foul shots while Kansas made just one of four. For the game, Kansas out- rebounded the Cowboys 41-26.
