How the Men’s College World Series works

Every year, the best teams in college baseball compete in the NCAA Division I baseball tournament, vying for the chance to play in Omaha at the Men’s College World Series.

Here is how the NCAA Division I baseball tournament works, including the history and format.

What is the difference between the Division I baseball tournament and the Men’s College World Series?

The NCAA Division I baseball tournament is a 64-team tournament in the spring. After two rounds of play (which each consist of multiple games), there are just eight teams left. These eight teams then head to Omaha, Nebraska, for the Men’s College World Series. The MCWS is the culmination of the DI tournament, where the teams compete in two brackets, with the winners of each meeting in the MCWS finals, a best-of-three series to decide the NCAA champion.

When did the Men’s College World Series start?

The first-ever NCAA Division I baseball tournament was in 1947, and would barely be recognized as the same tournament nowadays. The 1947 tournament featured just eight teams, which were divided into two four-team, single-elimination brackets. The two winners — California and Yale — then met in a best-of-three final in Kalamazoo, Michigan. California went undefeated through the inaugural CWS and beat Yale to capture the first title.

• 1949: The final was expanded to a four-team, double-elimination format, and the site changed to Wichita, Kansas.
• 1950: Site moves to Omaha, Nebraska.
• 1954: Field expands to 23 teams. The field size bounces around between 21 and 32 for the next two decades. In the 22 years between 1954 and 1975, the field is never the same size two years in a row.
• 1976: Field expands to 34 teams, where it will stay until 1982.
• 1982: Field expands to 36 teams. Will expand multiple times in the next few years, before settling at 48 teams in 1987, where it will stay until 1999.
• 1988-1998: The eight regional champions are seeded into two four-team brackets. Those two brackets play…
