The boys basketball state tournament field will be decided this week, and some of the state's best will tumble and have to get ready for spring break.

Three No. 1 seeds have already been ousted, only one of which was in the Star Tribune's statewide Minnesota Top 25 rankings. That was No. 5-ranked Hopkins (26-2), which lost to No. 4-rated Wayzata (25-4) in the Class 4A, Section 6 championship Tuesday night.

The other two section favorites to fall were Southwest Christian in Class 2A, Section 5 and Springfield in Class 1A, Section 2.

All four classes are represented in the Top 25. The top team in each classification is No. 1 Cretin-Derham Hall in Class 4A, No. 2 Mankato East in Class 3A, undefeated and ninth-ranked Albany in Class 2A and No. 25 Cherry in Class 1A.

Also undefeated are No. 8 Tartan in Class 4A and No. 11 Waseca in Class 2A.

All schools are Class 4A unless noted.
