Tennessee guard Josh Richardson realized he needed to give his team a spark.
The 6-foot-6 senior proceeded to produce the kind of pyrotechnics that left No. 15 Butler's four-game winning streak in ashes.
Richardson scored 18 of his 20 points after halftime Sunday, and Tennessee overcame a 12-point second-half deficit to beat Butler 67-55. Richardson shot nine of 13 and had a career-high six steals.
Butler (8-2) led 37-25 after Kellen Dunham's three-pointer in the opening minute of the second half, but Richardson scored the game's next eight points to spark a 12-0 run that tied the score. Tennessee (4-3) took the lead for good with 6:15 left.
Kevin Punter added 18 points as the Volunteers earned their first victory over a ranked opponent since the arrival of coach Donnie Tyndall, who took over Tennessee's program this season.
After Butler's Andrew Chrabascz hit a three-pointer to cut Tennessee's lead to 58-55 with 2:40 left, Derek Reese answered by banking in a three-pointer to start a game-ending 9-0 run.
"Thank God it went in," Reese said. "The bank is open on Sundays sometimes."
Clemson 72, Auburn 61: Rod Hall tied his career-high with 20 points to lead host Clemson. Clemson used an 11-2 run early in the second half to take control over Auburn (3-5), which lost its third straight.

Northern Kentucky 107, Cincinnati-Clermont 53: Deonte Cole scored 15 points in 17 minutes Sunday, and Northern Kentucky rolled past Cincinnati-Clermont.
Cole had two three-pointers early as Northern Kentucky (4-5) jumped to 19-5 lead in the opening minutes. The Norse led 49-29 at halftime and never trailed.
Tyler White added 13 points, and Anthony Monaco, Dean Danos and Tayler Persons each scored 11 for NKU. The Norse were 16 of 31 from three-point range with Cole five of seven, Monaco three of four and Danos three of six.
"The last two practices we haven't shot well," NKU Coach Dave Bezold. said. "And to see it come together today was really rewarding. When you make those shots it relaxes you on both ends of the floor."
All 14 NKU players who entered the game scored as the Norse got 68 points from the bench. Northern Kentucky also had a 58-29 advantage on the boards.
No. 22 West Virginia 69, Marshall 66: Juwan Staten scored 15 points, including two free throws with seven seconds left to preserve No. 22 West Virginia's victory. Jonathan Holton and Jevon Carter add 14 points apiece for the Mountaineers.
