INDIANAPOLIS - Duke was selected as a No. 1 seed in the NCAA tournament for a record-tying 10th time Sunday, while Connecticut and Villanova led the Big East's unprecedented eight teams in the field with top seeds of their own.
Memphis was the final No. 1 chosen among tournament's 65 teams.
Duke's 10th No. 1 selection matched North Carolina for the most ever. It is Connecticut's fourth top seeding and the first time for both Villanova and Memphis.
Eight Big East teams broke the conference's own previous record of seven, which it had shared with the Big Ten. The Big East did it in 1991; the Big Ten in 1990, 1994, 1999 and 2001.
This year's bracket features six teams each from the Big Ten and Southeastern Conference. The Atlantic Coast, Big 12, Missouri Valley and Pac-10 each had four teams chosen.
Among the teams which had been mentioned as possible at-large teams but weren't selected were Cincinnati, Creighton, Florida State, Hofstra, Maryland, Michigan and Missouri State.
Duke (30-3), assigned to the Atlanta regional, will open the tournament Thursday near home in Greensboro, N.C., against Southern University. Also at Greensboro, eighth-seeded George Washington (26-2), the only Division I team with less than three losses, faces ninth-seeded North Carolina-Wilmington.
The other teams in that part of the bracket will play at Jacksonville, Fla., with fifth-seeded Syracuse, the upset winner of the Big East tournament, against 12th-seeded Texas A&M, and fourth-seeded LSU facing Iona.
Texas is the No. 2 seed in the Atlanta regional. The Longhorns, who lost to Kansas in the Big 12 tournament championship game Sunday, will play Pennsylvania in Dallas in a doubleheader with seventh-seeded California against 10th-seeded North Carolina State.
The other games in that regional are at Auburn Hills, Mich., with sixth-seeded West Virginia against No. 11 Southern Illinois and third-seeded Iowa, the Big Ten champions, against No. 14 Northwestern State.
Memphis (30-3), which lost just one game in Conference USA this season, heads the Oakland Regional and will play Oral Roberts, which was last in the tournament in 1984, at Dallas in the first round.
The other game in that doubleheader will have eighth-seeded Arkansas against No. 9 Bucknell, which had the upset of last year's tournament, beating Kansas in the first round.
At Auburn Hills, fourth-seeded Kansas will play Bradley, while fifth-seeded Pittsburgh faces No. 12 Kent State.
UCLA was the No. 2 seed in the regional and the Pac-10 champions will play Belmont, making its NCAA debut, at San Diego and seventh-seeded Marquette faces No. 10 Alabama.

Connecticut, along with Duke the only teams to be ranked No. 1 this season, is the top seed in the Washington Regional. The Huskies (27-3), who were beaten by Syracuse in the Big East quarterfinals, will play Albany, which is making its first appearance, in Philadelphia. The other game in that doubleheader has eighth-seeded Kentucky against No. 9 UAB. Those teams met in the second round in 2004, with the Blazers stunning top-seeded Kentucky.
Washington, the fifth seed in the regional, plays Utah State in San Diego, while No. 4 Illinois, which lost in the championship game last season, faces No. 13 Air Force, one of the surprise at-large picks in the field.

This will be the 27th tournament for Arizona coach Lute Olson, tying him with Dean Smith and Bob Knight for the most in NCAA history. It is Olson's 22nd straight appearance with Arizona, moving him within one of Smith's record set at North Carolina from 1975-97.
At Salt Lake City, fourth-seeded Boston College, which finished tied for second in its first season in the ACC, plays 13th-seeded Pacific and fifth-seeded Nevada faces No. 12 Montana.
