AUBURN, Alabama — Back and forth they went on Auburn's Senior Day.
Auburn senior Bryce Brown and junior Jared Harper came up big, and so, too, did breakout star sophomore Chuma Okeke.
The 84-80 victory against No. 5 Tennessee was not only huge for the Tigers' outgoing seniors, it was big for the program. The Tigers are assured a No. 4 or 5 seed in the upcoming SEC Tournament and sent Tennessee to only its third loss in the SEC.
And Auburn (22-7, 11-7 SEC) remained undefeated in the month of March as the Tigers won their fourth straight game in a game that looked more the part of a heavyweight fight in a game that featured seven lead changes.
It was the most energetic crowd of the season at Auburn Arena, and for good reason: Tennessee and Auburn went back and forth throughout the second half after the Tigers fell behind as many as 11 points in the first half.
Auburn opened the second half with a 7-0 run to cut into Tennessee's lead, but in the end it was Auburn's seniors stepping up: most notably the late-game hero of many games: Harper.
He broke a tie with a 3-pointer with 3:28 remaining, hit another with 2:46 remaining and the Tigers held off the Volunteers with four more free throws by Harper and a pair to ice it by Samir Doughtywith six seconds remaining. Tennessee coach Rick Barnes believes one of Harper's 3-pointers in the final minutes was tipped in by Anfernee McLemore and should have counted as two.
"It should have been a two-point play," Barnes said. "That’s what everyone has said as walked here."
The play was not reviewable and stood as a 3-pointer.
Tennessee's Jordan Bowden was forced along the out-of-bounds line near the Auburn student section with less than 10 seconds remaining and the Vols trailing by two. The steal was forced by Okeke, the star of the game for both squads. He scored 22 on 9 of 14 shooting, hit three 3-pointers, grabbed five rebounds and also had four steals. The forward matched up well against Tennessee's player of the year candidate, Grant Williams. He finished with 25 points, but when Auburn placed Okeke on him, he struggled more often to get in position offensively and that was a huge difference in the game.
Auburn will be the No. 4 seed if South Carolina loses its regular-season finale today or it will be the No. 5 seed if the Gamecocks win.
