MANHATTAN, Kan. — Austin Reaves threw up his arms in frustration.
Reaves' 3-pointer in the closing seconds hit off the rim as he pleaded for a foul call that never came.
Reaves came up big most of the night but it wasn't enough as OU's vexation at Bramlage Coliseum continued Tuesday night.
The No. 7 Sooners struggled to find much of a rhythm before seemingly taking control, only to see Kansas State senior Mike McGuirl catch fire at the end to lift the Wildcats to a 62-57 upset.
OU hasn't won at the "Octagon of Doom" since 2012.
