Chris Duhon scored 11 and hit a key 3-pointer in the final minute to lift No. 1 Duke past Florida State 56-49 on Thursday night.
J.J. Redick scored 24 to lead the Blue Devils (17-1, 6-0 Atlantic Coast Conference), who have won 14 straight overall and 37 in a row at home. Sean Dockery went scoreless but had two big steals late as Duke remained the only unbeaten team in ACC play.
Duke's home winning streak is the nation's second-longest. Pittsburgh has won 38 in a row.
Tim Pickett scored 16 for the Seminoles (14-6, 3-4), who were trying to beat a top 10 team in three straight games for the first time in school history. Florida State, which has beaten North Carolina and Wake Forest in the past week, fell to 0-14 all-time at Cameron Indoor Stadium.
Florida State also was seeking its first three-game winning streak in the conference in more than nine years.
The Seminoles had beaten the Blue Devils at home each of the past two seasons. But they never had fared well at Cameron, losing their 13 previous games by an average of 21 points.
They hung around most of the way Thursday, playing scrappy defense and giving Duke one of its toughest challenges since it took the No. 1 ranking two weeks ago.
The Blue Devils led by 12 at halftime and took their largest lead at 49-34 on a 3-pointer from Redick with 9:28 to play.
But the Seminoles answered with a 15-2 run, getting a three-point play from Alexander Johnson and a 3-pointer from Pickett to cut the deficit to 51-44 with 3:22 left. Von Wafer then had a stickback and a 3-pointer that cut it to 51-49 with one minute left.
But Duhon had an answer.
Coming out of a timeout, he took the inbounds pass from Daniel Ewing near midcourt, dribbled to the left wing and fired a 3-pointer. The shot swished through with 36.4 seconds to go, giving Duke a 54-49 lead and setting the 9,314 fans into a frenzy.
Dockery then came up with two big defensive plays. After Duhon's 3-pointer, Dockery stole Wafer's inbounds pass and was fouled. He missed the free throw but added another steal on Adam Waleskowski's pass.
Redick added two free throws with 5.7 seconds left to seal it.
The Seminoles played solid defense throughout, contesting Duke shots with their man defense and holding the Blue Devils to 39 percent shooting. They also pulled down 20 offensive rebounds.
FSU shot just 30 percent.
