Walker III's three-pointer at the 13:55 mark of the first half put the Tigers up 8-4, but ASU would respond with a 13-2 run that was capped off by a D.J. Horne three with 7:33 to go before the halftime break.
The Sun Devils looked to be on the verge of the game's first double-digit lead near the end of the first half, but the Tigers clawed their way back into the thick of things with a pair of jumpers from Walker III to cut the ASU lead down to 28-24 at the half.
TSU scored on the first possession of the second half on a long range shot from Henry to pull the Tigers to within 28-27.
