Thomas’ jumper with 1:13 on the clock cut the Sparks’ deficit to 73-72 before Smith calmly sank a pair of free throws. Thomas then made 1-of-2 from the line and Braxton sank a pair on the other end to make the score 77-73.
McWilliams-Franklin missed a layup and a chance to trim the deficit to two points with 20 ticks left, and Detroit held on for the victory from there.
