The flood of spring postseason bracket releases continued on Wednesday. Regional baseball brackets were released for Class 3A, 4A and 5A, signaling the official start of the postseason.
In order to advance to the state tournaments, which begin play next week, teams have to win their region.
These brackets were created and seeded, in part, with data from the final RPI standings of the regular season.
Find the full brackets here:
After finishing the regular season undefeated, Mountain Vista earned the top overall seed heading into the Class 5A playoffs.
The Golden Eagles got wins over Heritage, Cherry Creek and Arapahoe this year. Those three teams all finished in the top eight of the final RPI ratings, meaning they'll host regional games as well.
Pine Creek, Legacy, Fruita Monument and Mountain Range are the remaining host teams for 5A.
Defending champion Rocky Mountain is a No. 3 seed in Legacy's region.
A year after missing the 4A state tournament, Windsor enters regionals as the top overall seed. The Wizards finished the regular season with a 18-1 record, the only loss coming at the hands of Holy Family.
Defending champion Valor Christian is the No. 2 overall seed in regionals and will also host this weekend.
Longmont, Fort Morgan, Palmer Ridge, Pueblo West, Denver North and Palisade will also host regional tournaments this weekend.
Lamar enters the 3A bracket as the top overall seed. The Savages advanced to the 3A state tournament a year ago as the top overall seed, but lost the tournament's opening game to Colorado Academy.
They lost 1-0 to Tri-Peaks rival La Junta the next day, ending a disappointing postseason.
The top eight seeded teams also earned the right to host their regional games. University, Eaton, Sterling, Faith Christian, Alamosa, Delta and Bennett round out the host teams for this upcoming weekend.
Defending champion Valley will play as the No. 3 seed in the Sterling region.
