Air Force (26-9) proceeded to outscore the Tigers, 12-3, the rest of the way, capped by a steal off an inbounds pass and 3-pointer by Dan Nwaelele with three seconds left. Following a timeout, the Tigers inbounded the ball without incident to preserve the one-point win.

The Tigers' 25 wins matches the school record set in 1986-87.
