KANSAS CITY, Kan. (AP) -- Marcus Smart left one last impression on Texas Tech, scoring 18 points and leading seventh-seeded Oklahoma State to an 80-62 victory over the ninth-seeded Red Raiders on Wednesday night in the first round of the Big 12 tournament.
Smart also had seven rebounds, seven assists and six steals for the Cowboys (21-11), who built a 46-23 lead by halftime and then cruised into Thursdays' quarterfinal against top-seeded Kansas.
Markel Brown had 20 points, Phil Forte added 14 off the bench and Le'Bryan Nash scored 10 for Oklahoma State, which has never lost in 10 first-round games at the Big 12 tournament.
Jaye Crockett led the Red Raiders (14-18) with 20 points. Dejan Kravic added 18 points and 12 rebounds.
Their victory also meant first-year Texas Tech coach Tubby Smith finished with a losing record for the first time in 23 seasons, spanning stints at Tulsa, Georgia, Kentucky and Minnesota.
