Texas went into the locker room on Senior Night leading Baylor, 36-34, on Monday night at the Erwin Center.
The Longhorns, who fell to the Bears in overtime in their Big 12 opener two months ago, shot 45.8 percent from the field and had two players score in double figures. Sophomores Sheldon McClellan and Myck Kabongo both scored 10 points on 4-for-7 shooting.
Pierre Jackson, the Big 12's leading scorer, scored a game-high 13 points and hit three three-pointers in the first half. The rest of his team scored 21 points and shot just 31.3 percent from the floor.
Texas took its biggest lead of the half after a Kabongo layup put the Longhorns up, 12-9, at the 14:39 mark. But a 9-0 run by Baylor gave the Bears their biggest lead of the first half at 18-12.
Neither team was able to hold onto a lead for very long after that as Texas worked its way back in the game and took a one-point lead into the final minute of the first half. Jackson hit a pair of free throws to give Baylor a 34-33 advantage before Jonathan Holmes' three-pointer with 13 seconds left put the Longhorns up two points heading into the second half.
