TENNESSEE GUARD Josh Richardson realized he needed to give his team a spark.

The 6-6 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 yesterday and Tennessee overcame a 12-point, second-half deficit to beat visiting Butler, 67-55.

Richardson shot 9-for-13 and had a career-high six steals.

"I just saw we were dead and didn't really have any scoring output in the first half," Richardson said. "KP [Kevin Punter] was playing good, and that was about it, so I decided to come up with it."

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 on Armani Moore's basket with 6:15 left.

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.

"It hurts when teams like that hit threes," Punter said. "It kind of takes the life out of you. But you've just got to stay with it if you want to win. We stayed with it, we kept grinding, they coughed it up a few times and we capitalized."

Butler shot 6-for-23 and committed nine turnovers in the second half. Tennessee outscored Butler in points off turnovers, 19-5.

Dunham scored 16 points, but only two of those came in the game's final 19 minutes. Kelan Martin added 13 for Butler.
