NCAA Tournament: Brackets set with Duke men, UConn women leading fields

Who will win the men's and women's NCAA Tournament? The 68-team brackets were revealed Sunday.

The march to college basketball's national championship is officially under way.

Duke, Arizona, Michigan and Florida are the teams to beat in the NCAA men's basketball tournament after each earned a top seed in the 68-team bracket Sunday.

The top overall seed in the women's tournament is Connecticut, the reigning national champion and last undefeated team in the country. Joining the Huskies as No. 1 seeds are UCLA, Texas and South Carolina.

The women's Final Four begins April 3 in Phoenix, with the title game April 5. The men's Final Four is on April 4 and April 6 in Indianapolis.

Duke, the ACC champion, earned the men's top overall seed by building a 32-2 record; the Blue Devils haven't lost since Feb. 7. Their credentials are strong with wins over reigning national champion Florida and Michigan, but they will play in a difficult East region that includes Kansas, Connecticut and St. John's.
