The College World Series (CWS), officially the NCAA Men's College World Series (MCWS), is a baseball tournament held each June in Omaha, Nebraska. The MCWS is the culmination of the National Collegiate Athletic Association (NCAA) Division I Baseball Championship tournament—featuring 64 teams in the first round—which determines the NCAA Division I college baseball champion. The eight participating teams are split into two, four-team, double-elimination brackets, with the winners of each bracket playing in a best-of-three championship series.
