The National League of Professional Baseball Clubs, known simply as the National League (NL), is the older of two leagues constituting Major League Baseball, and the world's oldest extant professional team sports league. Founded on February 2, 1876, to replace the National Association of Professional Base Ball Players, it is sometimes called the Senior Circuit. The other league of Major League Baseball is the American League, founded in 1901 (sometimes called the "Junior Circuit" because it started 25 years after the NL). The two league champions of 1903 arranged to meet in the World Series and, after the 1904 champions failed to do likewise, the two leagues have arranged to meet in that annual culmination of the American baseball season, failing to do so only in the strike-shortened 1994 season. National League teams have won 44 and lost 62 of the 106 World Series played between these two leagues from 1903 to 2010. The San Francisco Giants are the reigning League Champions; they went on to defeat the Texas Rangers in the 2010 World Series. This was the first time the franchise has won the World Series since moving to San Francisco. The New York/San Francisco Giants and the Brooklyn/Los Angeles Dodgers lead the league with 21 National League titles each, while the St. Louis Cardinals are the National League team with the most World Series wins, 10.
