STILLWATER, Okla. -- Marcus Smart scored 20 points to help No. 9 Oklahoma State defeat TCU 82-50 on Wednesday night.
Smart, the reigning Big 12 player of the week, also had eight rebounds and five assists for the Cowboys (15-2, 3-1 Big 12).
Markel Brown scored 14 points and Le'Bryan Nash added 13 points and eight rebounds for Oklahoma State, which needed to win to stay within range of Big 12 leader Kansas. The 15th-ranked Jayhawks (4-0 Big 12) host the Cowboys on Saturday.
Oklahoma State shot 47 per cent from the field to win for the eighth time in nine games and improve to 9-0 at home.
Karviar Shepherd scored 13 points and Amric Fields and Michael Williams each added 11 for the Horned Frogs (9-7, 0-4) in their most lopsided loss of the season.
The Horned Frogs were blown out for the second straight game ---- they lost 88-62 at Baylor Saturday.
Oklahoma State held TCU to 29 per cent shooting. Kyan Anderson, who entered the game leading the Horned Frogs with 15.6 points per game, finished with eight points on 2-for-8 shooting.
The Cowboys have been concerned about rebounding since post player Michael Cobbins went down for the season with a ruptured left Achilles' tendon late last month, but OSU outrebounded the Horned Frogs 46-33.
Oklahoma State led by 14 at halftime before stretching its lead in the early minutes of the second half. A pair of free throws by Kamari Murphy pushed OSU's lead to 48-29, and a tip-in by Smart pushed the Cowboys' lead past 20 points for the first time.
A lob from Smart led to a two-handed jam by Brown that gave the Cowboys a 71-47 edge, and OSU cruised from there.
Smart hit three 3-pointers in the first four minutes of the game to give Oklahoma State a 9-4 lead. A fast-break jam by Murphy gave the Cowboys a 28-15 lead with 6:55 left in the first half.
The Cowboys shot 55 per cent from the field in the first half and made 7 of 11 3-pointers. Smart scored nine points before the break and Brown added eight. Shepherd and Williams each scored seven points in the first half for TCU.
