From wikipedia's college baseball page:
College baseball is <font color="#002bb8">baseball</font> that is played on the intercollegiate level at institutions of <font color="#002bb8">higher education</font>. Compared to <font color="#002bb8">football</font> and <font color="#002bb8">basketball</font>, college competition in the <font color="#002bb8">United States</font> plays a less significant contribution to cultivating <font color="#002bb8">professional</font> players, as the <font color="#002bb8">minor leagues</font> primarily fulfill that role.</p>
As with other intercollegiate sports, most college baseball is played under the auspices of the <font color="#002bb8">NCAA</font> or the <font color="#002bb8">NAIA</font>. The NCAA writes the rules of play, while each sanctioning body supervises season-ending <font color="#002bb8">tournaments</font>. The final rounds of the NCAA tournaments are known as the <font color="#002bb8">College World Series</font>; one is held on each of the three levels of competition sanctioned by the NCAA. The College World Series for Division I takes place in <font color="#002bb8">Omaha, Nebraska</font> in June, following the regular season. The playoff bracket for Division I consists of 64 teams, with four teams playing at each of 16 regional sites (in a <font color="#002bb8">double-elimination format</font>) in late May. The 16 winners advance to the Super Regionals at eight sites, played head-to-head in a best-of-three series. In reference to the University of Mississippi (aka "Ole Miss") baseball team's 37-year absence from the College World Series, OMAHA has also been coined an acronym for "Ole Miss At Home Again". <font color="#3366bb">[1]</font> <font color="#3366bb">[2]</font>The eight winners then advance to the College World Series, a double elimination tournament (actually two separate four-team brackets) to determine the two national finalists. The finalists play a best-of-three series to determine the Division I national champion. In <font color="#002bb8">2009</font>, the winner of the College World Series was the <font color="#002bb8">LSU Tigers</font>.</p>
