One basket into the second half, Tennessee had a stunning 27-point lead over Miami.
The Lady Vols nearly wasted it all before snapping the Hurricanes' 41-game home winning streak.
Bashaara Graves scored 20 points, Andraya Carter added 16 and No. 24 Tennessee held on to top No. 23 Miami 79-67 on Sunday, becoming the first road team to win on the Hurricanes' home floor since Feb. 21, 2010.
''We didn't want to lose the lead the way we did, but we finished with a 'W,''' said Tennessee's Cierra Burdick, who had 10 rebounds. ''And that's what matters. This was a big-time win against a big-time opponent, on the road, so I'm nothing but proud of my team.''
Ariel Massengale added 14 points and was a perfect 10-for-10 from the foul line for the Lady Vols (3-1).
Tennessee shot 42 percent, compared with only 32 percent by the Hurricanes.
