Kerwin Roach Jr. scored 15 points, all in the second half, and added six rebounds, as Texas closed the game on a 16-2 run to defeat Oklahoma State 62-50 Friday night in the regular season finale for both.
Isaiah Taylor added 12 points for No. 23 Texas (20-11, 11-7 Big 12), which reached the 20-win plateau for the 16th time in the last 17 seasons.
Leyton Hammonds scored 20 points and added six rebounds to lead Oklahoma State (12-19, 3-15), which lost its sixth straight and ninth in its last 10.
After the teams entered the second half tied at 29, neither squad was able to build more than a three-point lead through the first 15 minutes.
Hammonds' long jump shot put the Cowboys ahead 48-46 with 7:44 remaining, but Roach capped off a 6-0 Texas run with a layup to put the Longhorns on top, 52-48, with 4:32 remaining.
