Texas forward Conner Lammert hit a 3-pointer with 1:10 to play overtime, and guard Eric Davis, Jr. added another 40 seconds later as the Longhorns outlasted giant-killer Texas-Arlington 80-73 in overtime Tuesday at the Erwin Center in Austin, Texas.

The game was tied at 71-71 before Lammert sank the 3-pointer with the shot-clock winding down and a defender in his face.

Point guard Isaiah Taylor led the Longhorns (3-3) with 21 points, all in the second half and overtime, while guard Javan Felix scored 18 points for Texas.

Center Kevin Hervey poured in 15 points and grabbed 15 rebounds for Texas-Arlington (5-2). Guard Drew Charles added 12 points for the Mavericks, who out rebounded Texas 46-33.

The game was tied at 67-67 at the end of regulation after a spirited final minute that saw plenty of contact in the lane on drives at both ends of the floor.

The Mavericks held a 29-21 advantage with 2:48 to play in the half before Texas got a jumpstart on guard Kerwin Roach Jr.'s soaring dunk that posterized Texas-Arlington forward Jorge Bilbao. Still, Texas-Arlington led 31-27 at halftime on the strength of 9-0 and 7-0 runs, a stingy defense and a 20-16 rebounding edge over the taller Longhorns.

Texas tied the game at 38-38 on a 3-pointer by Lammert with 16:02 to play, and the rest of the game went back and forth, with neither team leading by more than five points.

Texas-Arlington, which beat Ohio State and Memphis on the road earlier this season, shot just 30 percent from the floor in the second half, including 1-for-9 from 3-point range.
