In the 2002 World Series, both the Angels and the Giants made the playoffs as wild card teams.
The world series
In all, there are 30 Major League teams. The New York Yankees are the best by far with 26 World Series wins.
American Professional Baseball is made up into 2 divisions or leagues. After a season of play and a couple of weeks of playoffs the 2 leagues, the American and National send their champions to the World Series. Although called the World Series there are only American teams participating. The recent World baseball classic showed American baseball is not the only dominate team around.
The Tampa Bay Rays represented the American League and the Philadelphia Phillies represented the National League. The Phillies won the series in 5 games. EC
30 teams
While the NHL is the top, the best, pro league in the world with 30 teams, there are many pro leagues throughout the world. There are at least 6 pro leagues in North America alone besides the NHL. Then you must consider that Sweden, Russia, Finland, Czech Republic, Slovakia, Germany, ETC, have their own pro leagues. For example there are at least three levels of pro hockey in Sweden alone that I know of. I haven't counted all teams in all leagues, but I would be safe in saying that there are at least several hundred pro teams in the world, even in Australia.
I assume you mean MLB (Major League Baseball)... Each of 30 teams play 162 games during the regular season. Four teams from each of the two leagues make the playoffs. The first round is a 5 game series, the second round is a 7 game series and the third round (the World Series) is a 7 game series.
soccer is the sports that has most pro leagues. It even has a World cup.
Every league in the world of football there is on fifa 11 except for 2
The Seattle Mariners, the Washington Nationals, and the Texas Rangers are the only teams that have never made it to the World Series.
There are 2 leagues. American League and National League.
There have been alot of teams that have won the world series after starting 4-2.
