GREENSBORO, N.C. – Duke found the perfect remedy for that two-game losing streak at the end of the regular season – a short trip to the Greensboro Coliseum for the Atlantic Coast Conference tournament, an almost unbeatable combination.

Three hard-fought victories later, the third-ranked Blue Devils added another title and wrapped up a no. 1 seed in the tournament that matters most.

J.J. Redick had consecutive 3-pointers down the stretch to give Duke the lead for good, Shelden Williams and Greg Paulus added clutch free throws in the final seconds, and the Blue Devils held off no. 11 Boston College 78-76 yesterday in the championship game.

The Blue Devils (30-3) won the tournament for a record 16th time. Seven have come in the past eight years, an amazing run of superiority for Hall of Fame coach Mike Krzyzewski and his program. Since 1998, the Blue Devils are 25-2 in this event.

This one was far from easy, and not simply because Duke lost the final two games of the regular season. B.C. knocked off North Carolina in the semifinals and rallied from a 10-point deficit in the second half against Duke.

The Eagles (26-7) led 71-68 before Redick, the tournament MVP, took over. The second-leading scorer in Division I made one 3-pointer to tie it before Craig Smith converted two free throws on the other end. Redick then used a pick from Williams to get free and launched another jumper from a few steps behind the 3-point line.

Redick scored 26 points while Williams added 18 for Duke. Hinnant led the Eagles with 20 points and Smith finished with 19 points and 10 boards.

FLORIDA 49, S. CAROLINA 47 A very different Florida team brought the Gators a second straight Southeastern Conference tournament championship in Nashville.

Joakim Noah, one of Florida’s three new starters this season, scored with 11 seconds left, then blocked a shot at the other end, and the 16th-ranked Gators held off South Carolina 49-47 in a sloppy title game in which the Gamecocks nearly pulled off the improbable upset.

Now Florida (27-6) can focus on improving on a second-round loss in last year’s NCAA tournament.

The Gamecocks (18-15) already were the lowest seed ever to play in this championship. With winning the title their only chance of reaching the NCAA tournament, they were trying to become the first team since Arkansas in 2000 to win four games in four days.

IOWA 67, OHIO ST. 60 Jeff Horner scored 14 of his 16 points in the second half and added 10 assists to lead no. 20 Iowa over Ohio State 67-60 in the Big Ten tournament championship game. Adam Haluska added 15 points and eight rebounds for the Hawkeyes (25-8), who won their first conference tournament since 2001.

Jamar Butler had 19 points and J.J. Sullinger added 15 for the top-seeded and seventh-ranked Buckeyes (25-5), who fell short in their quest to win both the regular season and tournament titles.

Iowa extended its winning streak to five games and ended Ohio State’s winning streak at seven. Ohio State’s Terence Dials, the conference player of the year, had 10 points and nine rebounds despite playing only 22 minutes because of foul trouble.

KANSAS 80, TEXAS 68 No. 17 Kansas was terrific outside and played great defense to beat no. 8 Texas in the final of the Big 12 tournament. The Jayhawks (25-7) have won 15 of 16 games, the only loss on February 25 to Texas (27-6).

Mario Chalmers scored 15 points for Kansas, which hit a season-high 12 3-pointers in 24 attempts. Texas forward LaMarcus Aldridge scored only five points on 1-of-5 shooting and was limited to 28 minutes because of foul trouble.

P.J. Tucker, the Big 12 player of the year, kept Texas in it with 16 points and eight rebounds, and Kenton Paulino had 19 points, including five 3-pointers.

Kansas won its first Big 12 title since taking the first three, a run that ended in 1999.
