With their perfect ACC season on the line, Duke stars Alana Beard and Iciss Tillis stepped up to make history.

Tillis scored all 21 of her points in the second half and added 10 rebounds, and Beard had 16 points and a career-high 20 rebounds as No. 2 Duke became the first women's team in ACC history to win four consecutive tournament titles with a 77-59 victory over No. 11 North Carolina last night in Greensboro, N.C.

"A dynasty will be complete when we win the national championship," Tillis said. "When I think of a dynasty, I think of national championships. I think we are right there, we just need one more piece of the puzzle."

Top-seeded Duke (31-1) won its 43rd consecutive ACC game, ran through the league undefeated for the second straight season and matched the Duke men (1999-2002) as the only conference teams to win four straight titles.

To do so, the Blue Devils beat North Carolina (27-5) for the ninth straight time in a rematch of last season's final.

* BIG TEN: Mary Jo Noon and Shereka Wright each scored 19 points and grabbed 11 rebounds as No. 10 Purdue beat No. 22 Ohio State, 67-65, to win the tournament title in Indianapolis.

It was the seventh straight season the Boilermakers have been the conference's regular season or tournament champions.

"It's just pride," Purdue Coach Kristy Curry said. "There was never a look in their eye like we couldn't do this, and I think that comes from the classes that were here before them. They play to win instead of playing not to lose."

The third-seeded Boilermakers (26-5) won the tournament for the fourth time -- but first since 2000 -- and advanced to the NCAA tournament for the 10th straight season. Purdue will host first- and second-round games at Mackey Arena.

* PAC-10: Tournament MVP Nicole Powell scored 13 of her 19 points in the first eight minutes and No. 9 Stanford opened up an early lead to defeat 21st-ranked Arizona, 59-49, to win the championship game in San Jose.

The top-seeded Cardinal earned the conference's automatic berth into the NCAA tournament.

Stanford (26-4) was determined to win after losing to Arizona State in the title game in last season's inaugural conference tournament despite going 18-0 in Pac-10 play.

Arizona's players exited the court in HP Pavilion without shaking hands with the Stanford players, but reluctantly returned for the awards ceremony.

Dee-Dee Wheeler led No. 3 seed Arizona (22-8) with 13 points.
