How do the NCAA baseball regionals work?

The NCAA baseball tournament is not your standard single-elimination, bracket format. The tournament kicks off with the regionals, followed by the super regionals, and ultimately the Men’s College World Series.

Regionals are a double-elimination format, with the 64 teams divided into 16, four-team mini-brackets. The top 16 teams in the nation each host a regional, and each of those 16 teams is the No. 1 seed in its regional. Games begin on Friday in a double-elimination format, with each bracket winner advancing to the super regionals.

Super regionals consist of 16 teams advancing to eight matchups, which are a three-game series. The winner of each super regional advances to the Men’s College World Series, which will see those eight teams split again into two brackets of four, in a double-elimination format. That builds to the Championship Series, which is a best-of-three series between the final two teams.

Who are the top 16 teams?

Here are the top 16 teams in the NCAA baseball tournament, ranked from No. 1 to No. 16. Each of these teams is hosting a regional this weekend, and the top eight are guaranteed to host a super regional … provided they advance.

No. 2 Georgia Tech (48-9)
No. 3 Georgia (46-12)
No. 4 Auburn (38-19)
