Ohio State, Kansas, Pittsburgh and defending champion Duke have been awarded the top seeds in this year's NCAA tournament, an expanded version of March Madness that will include 68 teams.
The Buckeyes defeated Penn State 71-60 in the Big Ten tournament final on Sunday and were named the top seed in the entire field. They'll play in the East region.
The tournament — and America's most-celebrated office pool — starts Tuesday with the first of four first-round games — the "First Four," as it's being called by the NCAA. Two of those games will pit the last of 37 at-large teams to make it into the field, an increase of three teams over years past.
Kansas is the Big 12 champion and will play in the Southwest, while Pitt earned a top seed despite losing in the quarterfinals of the Big East tournament and will play in the Southeast.
Duke beat North Carolina to win the Atlantic Coast Conference tournament and edge out Notre Dame for the last No. 1 seed. The Blue Devils, seeking to become the first repeat champion since Florida in 2006-07, will have to travel West to make the Final Four, as that regional is set for Anaheim, Calif.
The tournament concludes with the Final Four in Houston on April 2 and 4.
In the East region, Ohio State will open against the winner of an opening-round game between 16th seeds Texas-San Antonio and Alabama State. No. 8 George Mason will play No. 9 Villanova. No. 4 Kentucky will play No. 13 Princeton and No. 5 West Virginia will play the winner of a First Four matchup between No. 12 seeds UAB and Clemson.

In the West, Duke will start its journey near home in Charlotte, with a second-round game against No. 16 Hampton, while No. 8 Michigan will play No. 9 Tennessee. No. 5 Arizona will play No. 12 Memphis, the Conference USA champion, and No. 4 Texas plays No. 13 Oakland.

In the Southeast, No. 1 Pittsburgh plays the winner of 16th-seeded UNC-Ashville and Arkansas-Little Rock and last year's runner-up, No. 8 Butler, plays No. 9 Old Dominion. No. 5 Kansas State plays No. 12 Utah State and No. 4 Wisconsin plays No. 13 Belmont.
