Auburn trailed by 10 points early in the first half and still down by nine with six minutes left in the half, and needed late-game heroics from Johnson to prevail.

With Missouri up 51-50, Johnson took over in the final 1:27 by driving the basket and completing the three-point play. He followed with another driving basket to put Auburn up 55-51 with 47 seconds left.

Missouri's Javon Pickett hit a 3-pointer to cut the Auburn lead to one with 35 seconds to play, but Auburn grabbed three consecutive offensive rebounds and Missouri could not get the ball back for another shot.

Auburn finally got going offensively with Wendell Green Jr. hitting a pair of 3-pointers.

Missouri still led 27-20 with 4:25 left in the half, but then Auburn used an 8-0 run to take its first lead of the game. Johnson triggered that surge with a 3-point jumper, then a steal and lay-up.

After the first half ended tied at 31-31, Missouri edged ahead 39-36 with back-to-back baskets by Kobe Brown and Coleman's fast break layup for a 6-0 surge.
