Neither team scored again until Baugh made two foul shots with 34 seconds left. TCU’s Xavier Cork blocked Frankie Collins’ layup attempt, and Miles went just 1 of 2 from the line to increase the Horned Frogs’ lead to three.That allowed the Sun Devils’ DJ Horne the opportunity to tie the game 70-70 on a straightaway 3-pointer.TCU had 12.4 seconds left to get the last shot. Coles received a pass behind the arc, he made a move right and drove in to get his floater.

Chuck O’Bannon had 15 points and Baugh and Coles finished with 11 apiece.Horne went 4-for-5 from the arc en route to a team-high 17 points for Arizona State (23-13), which had throttled Nevada in the First Four to reach the round of 64.
