LUBBOCK, Texas (AP) -- Jarrius Jackson scored 26 points to lead Texas Tech past Baylor 85-74 on Wednesday night.
Jon Plefka had a career-high 22 points for the Red Raiders. His previous high, 19 points, came in a 73-70 loss to Baylor in Waco last month.
Tech has wins in four of its last five games and needs a victory at Iowa State on Saturday to go above .500 in Big 12 Conference play for the season.
The loss was the sixth in the past seven games for Baylor (13-15, 3-12). Tech held Aaron Bruce, the Bears' second-leading scorer, to two points.
Tech (19-11, 8-7) got its biggest lead at 75-62 with 4:56 remaining on a bucket by Jackson. The Bears pulled within 82-74 on two free throws by Tweety Carter with just more than a minute remaining. They got no closer down the stretch.
The Red Raiders trailed only briefly early in the game and withstood a couple of runs by the Bears in the first half. Baylor pulled within 53-51 early in the second half and stayed close the rest of the way only because they got the ball inside to Mark Shepherd and Josh Lomars.
The Bears finished with 42 points in the paint.
But fouls hurt Baylor. Lomars fouled out with just more than six minutes remaining in the game and Mamadou Diene, another of Baylor's big men, fouled out with about 13 minutes remaining in the game.
Curtis Jerrells scored 20 points and Carter added 13 to lead Baylor.
Jackson, Plefka and Martin Zeno finished with a combined 22 of 36 from the field for 48 points. Together they added 17 points on free throws.
Tech led most of the first half, and a livid Bob Knight was off the Red Raiders bench often. In one instance he stalked one official all the way to the baseline by the Tech bench to complain about a call.
At the break, he remained on the court and shouted at more than one official at center court before he walked off the court to loud applause from Tech fans.
The Red Raiders were hot early in the opening half, at one point hitting 81 percent from the field. They used a 15-4 run -- including 3-pointers by Zeno, Darryl Dora and Plefka -- to go up 21-9.
But Baylor hung tough and slowly crept back. Down by 10 with just more than five minutes remaining before the break, the Bears went on a 12-3 run to pull within 42-41. The Bears capped the run when Shepherd got a putback bucket off a rebound following Jerrells' miss on the second of two free throws.
Tech went to the free-throw line often and hit 11-15 in the first half. For the game, Tech hit with 23-of-31 from the line.
