TCU struggled with foul trouble, as two players fouled out for the Horned Frogs including leading scorer and team leader Kyan Anderson with 6:25 to play. WVU, though, had foul troubles of its own, as it sent TCU to the free-throw line for one-and-one with 11:27 to play in the second half.

It wasn't until the 5:38 mark of the first half that TCU missed a three – its eighth attempt.

That would be the last made bucket of the half, as WVU would lead 42-39 at the half despite the Horned Frogs shooting 52 percent from the field.
The Mountaineers were able to jump out to their largest lead of the game early in the second half behind some tough defending and inside shooting.
