Thirty teams battle from March to October for the 2019 Major League Baseball's World Series title. In MLB's regular season, they are divided into American and National leagues. Inside each league, they are regionalized into divisions according to their location. Only the best ones advance to the playoffs.
Since the creation of the World Series in 1903, eight franchises appeared in Major League Baseball and disappeared. This list doesn't take into account teams that disappeared before that date when American and National leagues had its own championships.
- Baltimore Terrapins
- Buffalo Blues
- Indianapolis Hoosiers
- Newark Peppers
- Brooklyn Tip-Tops
- Chicago Whales
- Kansas City Packers
- Pittsburgh Rebels
Some of the franchises had to relocate to survive. These teams still exist, but they changed their home city, their playing ground, their badge and their colours.
- Boston Braves became Atlanta Braves.
- Kansas City Athletics became Oakland Athletics.
- Montreal Expos became Washington Nationals.
- Philadelphia Athletics became Oakland Athletics.
- St. Louis Browns became Baltimore Orioles.
- Washington Senators 2 became Texas Rangers.
- Brooklyn Dodgers became Los Angeles Dodgers.
- Milwaukee Braves became Atlanta Braves.
- New York Giants became San Francisco Giants.
- Seattle Pilots became Milwaukee Brewers.
- Washington Senators became Minnesota Twins.
Many people miss the Montreal Expos, which hosted home games at the city's 1976's Olympic stadium. Las Vegas and Portland have shown interest in opening a franchise in recent months. The latest news como from Raleigh, North Carolina. The city is very interested in having a team and won't spare efforts to have it.
