These in-state rivals hadn't played each other in the tournament since 1987 with Tennessee winning that game, and they split the first two games in league play winning on each other's home court this season.
No. 10 seed Tennessee (16-15) kept its season alive by finishing the game on a 20-2 run started with 6:18 left after trailing 59-47. The Vols will play No. 21 Arkansas on Friday night in the quarterfinals.
Vanderbilt (19-13) snapped a five-game winning streak. The Commodores hit only one of their final 10 shots and turned it over five times down the stretch.
At one point, Richardson had scored 13 of Tennessee's first 15 points in the second half trying to keep the Vols close with a couple teammates on the bench in foul trouble.
Hubbs jumpstarted the comeback with a 3-pointer with 6:18 left. Kevin Punter followed with a 3, then Derek Reese added another 3. Hubbs' next 3, with 2:13 left, put Tennessee ahead 64-61 — the Vols' first lead since 18-16. They finished off the run at the line.
Vanderbilt came in shooting 50.8 percent from the floor in its winning streak. The Commodores got a layup from LaChance with 3:07 left, and that was their lone bucket after Jones' jumper put them up 59-47 with 7:18 left.
When Vanderbilt played at Tennessee on Feb. 26, Commodores coach Kevin Stallings left Knoxville with a win but was punished by his administration for a profane tirade directed at Baldwin for clapping in front of Vols forward Armani Moore.
Vanderbilt led 38-32 at halftime, and Baldwin scored the first six giving the Commodores their biggest lead at 44-32 on a layup a couple minutes into the second half. But Richardson, the senior guard, refused to let the Vols lose.
