Texas 83, Texas Tech 52

Lubbock, Texas — Freshman Tristan Thompson scored 20 points to lift No. 12 Texas to a rout over Texas Tech on Tuesday night.

Jordan Hamilton added 16 points and Cory Joseph had 15 for the Longhorns (13-3, 1-0 Big 12).

Texas got the ball inside with ease, scoring 50 points in the paint. The Longhorns were all over Texas Tech’s basket as well, pulling down rebounds off the Red Raiders’ many misses.

Texas pulled away midway through the first half and Texas Tech (8-9, 0-2) was unable to counter the Longhorns offense.

The Longhorns came into the game ranked fifth in the nation in field goal defense and easily continued that trend. They held the Red Raiders to 23 field goals on 59 attempts. It was the third-worst shooting performance — 39 percent — by Texas Tech this season.

The Longhorns outscored Texas Tech, 24-9, in the first 10 minutes of the second half for a 62-31 lead.

For a third straight year, the Red Raiders have lost their first two Big 12 games. They have lost nine straight in Big 12 regular season play dating to last season.

Baylor 74, Oklahoma 61

Waco, Texas — Perry Jones III scored a career-high 25 points and LaceDarius Dunn added 16 as Baylor beat Oklahoma for its record 15th straight home victory.

Dunn became only the second Baylor player to surpass 2,000 points for a career, while Quincy Acy added 15 points and a game-high eight rebounds for the Bears (12-3, 2-0 Big 12).

Steven Pledger led the Sooners (8-8, 0-2) with 17 points, and Cameron Clark added 16.

Baylor broke the Ferrell Center record it shared with Oklahoma. The Sooners were 14-0 on the Bears’ home court and 26-0 against them in Big 12 play before Baylor swept the series last year.

The Sooners, who lost their last nine Big 12 games last year and this season’s conference opener at Texas A&M, have now dropped 11 straight conference games. A loss at No. 12 Texas on Saturday would extend the streak to 12, Oklahoma’s longest since losing 15 straight Big 6 contests in 1930-31.

Dunn scored on a drive with 17:07 left to crack the 2,000-point barrier. The senior has 2,009 points, leaving him 180 behind Terry Teagle on the school’s all-time list and 247 behind all-time Big 12 leader Andre Emmett of Texas Tech.
