DURHAM, N.C. -- Jason Williams has been Duke's ignitor this season. On Tuesday night, he torched Boston College.
Williams scored a career-high 34 points and had nine assists as No. 2 Duke won its sixth straight game, a 97-75 victory over No. 25 Boston College.
Williams, arguably the best player in the country over the last month, scored more than 20 points for the fifth time in seven games. He's averaged 26 points and six assists in five games against ranked opponents this season.
Against Boston College, Williams keyed the decisive run early in the second half and hounded Eagles sharpshooter Troy Bell for most of the night.
"He controlled the game for them and did what he had to do," said Boston College coach Al Skinner, whose team has lost two of three after opening 11-0. "That was the difference."
Boston College (12-2) pulled within 44-42 less than a minute into the second half, but Williams' pull-up jumper and two assists keyed an 11-0 run in less than two minutes.
Williams slapped the floor on successive Boston College possessions to stir up the crowd, then raised his arms on the next two to bring the decibel level higher.
He sent the "Cameron Crazies" into a frenzy with 17:18 left, feeding Juneau's Carlos Boozer for a two-handed dunk that put the Blue Devils up 55-42.
Williams says it has been the encouragement of teammate Shane Battier that has led to his take-control attitude.
"That's one thing that he's said to me," said Williams, a sophomore. "The ball's in my hand the predominant time and I have to take control of it."
Duke (16-1) has averaged 101 points in six games since losing to Stanford on Dec. 21.
Williams hit 12 of 19 shots, including 5-of-10 from 3-point range, and had five rebounds. His previous high was 30 points against Temple on Dec. 2.
Bell, who had scored 20 or more points in four of his last five games, led the Eagles with 16, but was just 4-of-16 from the field. The combination of Williams and Battier forced Bell into several bad shots in the second half as he went 1-for-7.
"They screen for him a lot and if you try to get over the top, he can beat you without the screen," Duke coach Mike Krzyzewski said. "We decided that Jason had one side and Shane had the other side, and overall that was good."
Battier had 22 points, 15 on 3-pointers, and Boozer was 10-of-14 and scored 22. Both blocked four shots.
About the only mistake Williams made was a no-look pass to no one with six minutes left, but Duke led 81-62 at the time. He also goaded Kenny Walls into throwing an elbow with less than a second left, leading to technical for Walls and four free throws for Williams.
Duke went on an 11-3 run midway through the first half to build a 26-17 lead. Boozer's left-handed layup off a drive capped the run with 8:50 left.
Duke led 42-38 at halftime after struggling at times. The Blue Devils did a poor job of blocking out, leading to 13 Boston College offensive rebounds, and had 12 turnovers.
"We just need to rebound better," Krzyzewski said. "Over the last couple of games we've won big, but we've given up a lot of offensive boards and that bad habit hurt us. We did a much job of rebounding in the second half."
Kentucky 84, No. 4 Tennessee 74
Bogans scored 21 points and Tayshaun Prince had 16 to lead Kentucky to its seventh straight win.
Freshmen Jason Parker and Gerald Fitch added 10 points each for the Wildcats (10-5, 3-0 Southeastern Conference).
Vincent Yarbrough scored 17 of his 21 points in the first half to lead the Volunteers (16-2, 3-1), who shot only 39 percent (26-of-66) and were outrebounded 44-34 by the smaller Wildcats.
Kentucky led by eight points at halftime, and Tennessee cut the lead to 51-47 on a 3-pointer by Jon Higgins at the 16-minute mark. Bogans then scored nine points during a 16-2 run to increase the lead to 67-49 with 11:42 to play.
No. 13 Virginia 89, Florida St. 71
Keith Friel scored 15 of his 22 points on 3-pointers to lead five Virginia players in double figures.
Chris Williams added 20 points, six rebounds and three steals for Virginia (12-3, 2-3 Atlantic Coast Conference), while Donald Hand had 15 points, Travis Watson 12 and Roger Mason, Jr. 11.
No. 19 Wisconsin 67, No. 14 Iowa 54
Roy Boone and Mark Vershaw each scored 18 points and Mike Kelley shut down Luke Recker in Wisconsin's victory.
The Badgers (11-4, 2-3 Big Ten), the victims of three straight last-minute road losses, made 29 of 35 free throws in winning for the ninth consecutive time at the Kohl Center.
The Hawkeyes (14-3, 3-1) had a double-digit lead early but were outscored 42-35 in the second half.
Kansas St. 80, No. 20 Missouri 59
Matt Siebrandt scored 20 points and Kansas State held Missouri to 20 percent shooting in the first half.
Just two days earlier, the Tigers (12-4, 3-1) had beaten Iowa State 112-109 in an exhausting four-overtime game, the longest in school history, and moved into The Associated Press rankings for the first time in two years.
Phineas Atchison had 16 points and Travis Reynolds had 13 points and 11 rebounds for Kansas State (8-7, 2-2), whose 86-78 victory over Iowa last month had been its only win over a Top 20 opponent in seven years.
Texas Tech 60, No. 22 Oklahoma 59
Jamal Brown hit a 5-foot bank shot between two defenders with 1.5 seconds remaining to give Texas Tech the victory.
Brown patiently held the ball before finding a crease in Oklahoma's defense and dropping in the game-winner for the Red Raiders (8-7, 2-2 Big 12).
Oklahoma (12-4, 1-3) had taken a 59-58 lead with 29 seconds left on a driving 8-footer by guard Nolan Johnson.
Brown led the Raiders with 18 points, while Andy Ellis had 16 and Cliff Owens 12.
No. 23 Iowa St. 84, Colorado 68
Martin Rancik scored 19 points and Jamaal Tinsley had 16 points, nine assists and six rebounds to lead Iowa State to its 30th straight victory at home.
Iowa State (14-3, 2-2 Big 12) finally managed to finish a game in regulation after playing a total of five overtimes in consecutive road losses to Oklahoma State and Missouri.
The Cyclones built a nine-point halftime lead, made their first five shots of the second half and contained Colorado (11-6, 1-3) the rest of the way with solid man-to-man defense.
Jake Sullivan added 12 points and Kantrail Horton had nine points and eight assists for Iowa State, which shot 58.5 percent and went 8-for-13 from 3-point range.
D.J. Harrison led Colorado with 18 points, while Jamahl Mosley and Michel Morandais each scored 12.
