DURHAM, North Carolina (Ticker) -- On a night for seniors at Cameron Indoor Stadium, a freshman stole the spotlight.
Freshman Shelden Williams recorded his sixth double-double in the first half and finished with 12 points and a season-high 17 rebounds and Dahntay Jones scored 14 points as Duke defeated Florida State, 72-56, in an Atlantic Coast Conference game.
Williams was hot from the outset as the Blue Devils (21-5, 11-4 ACC) used 13-2 and 13-0 runs in the opening 14 minutes to build a 28-7 advantage. He ended the first half with 11 points and 11 rebounds.
"I'm just out there doing what my team needs me to do - go out there playing hard on defense, helping out when somebody gets beat and trying to go out there and rebound," Williams said.
Jones, who along with fellow seniors Casey Sanders and Andre Buckner was playing his final home game, hit 4-of-8 from the field and all five attempts at the foul line.
"You've gotten to know them longer," Duke coach Mike Krzyzewski said. "They're more a part of you, and I believe a kid doesn't become completely a part of you until his senior year. In his senior year, the end is coming. You're closer to becoming a man, you have leadership and more responsibilities."
The win extended Duke's home winning streak to 28 games and put it in line for a share of the ACC title. The Blue Devils will clinch with a win over North Carolina on Sunday and a Wake Forest loss to North Carolina State on Saturday.
"I know a few guys who have lost their last games and just for us to win, it means a lot," said Sanders, who scored four points. "It means a big deal to me and I'm sure the rest of the seniors."
Daniel Ewing netted 12 points and freshman Shavlik Randolph added nine as Duke easily avenged a 75-70 loss at Florida State on February 2.
Mike Mathews scored all of his career-high 18 points in the second half for the Seminoles (13-13, 4-11), who ended the regular season with their 16th consecutive conference road loss.
Williams scored six points as Duke motored out front, taking a 13-2 lead on Randolph's bucket. After Anthony Richardson's layup got the Seminoles within 15-7, Williams sank a layup to ignite a 13-0 run.
Williams, who also had four blocks, fouled out with 2:53 remaining. His 17 boards were the most by a Blue Devil since Elton Brand grabbed 21 against Fresno State on November 27, 1998.
"Sheldon has been playing really well," Krzyzewksi said. "Our board play was excellent, our defense was excellent."
The Blue Devils held a 40-20 halftime cushion and grew the lead as big as 57-31 on Ewing's 3-pointer with 14:03 to go.
"It was obvious from the outset of the game that we weren't prepared, especially mentally and emotionally," Seminoles coach Leonard Hamilton said. "Duke's pressure caused us to make poor decisions. We turned the ball over and became impatient."
Chris Duhon scored 10 points for Duke, which held a 39-29 rebounding advantage but shot just 39 percent (22-of-56) from the field and committed 21 turnovers.
Richardson netted 15 points and Tim Pickett 11 for Florida State, which shot 41 percent (22-of-54).
The big difference was at the foul line, where the Blue Devils made 24-of-28 and the Seminoles were 8-of-15.
