Founded on February 2, 1876, to replace the National Association of Professional Base Ball Players, it is sometimes called the Senior Circuit, in contrast to MLB's other league, the American League, which was founded 25 years later. Both leagues currently have 15 teams. The two league champions of 1903 arranged to compete against each other in the inaugural World Series. After the 1904 champions failed to reach a similar agreement, the two leagues formalized the World Series as an arrangement between the leagues. National League teams have won 48 of the 112 World Series contested from 1903 to 2016. The 2016 National League champions are the Chicago Cubs.  - In baseball, a home run (abbreviated HR, also "homer", "dinger", "dong", "bomb", "blast", "goner" , "shot", or "four-bagger") is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home  safely in one play without any errors being committed by the defensive team in the process. In modern baseball, the feat is typically achieved by hitting the ball over the outfield fence between the foul poles (or making contact with either foul pole) without first touching the ground, resulting in an automatic home run. There is also the "inside-the-park" home run, increasingly rare in modern baseball, where the batter reaches home safely while the baseball is in play on the field. When a home run is scored, the batter is also credited with a hit and a run scored, and an RBI for each runner that scores, including himself. Likewise, the pitcher is recorded as having given up a hit, and a run for each runner that scores including the batter.  - The outfield is a sporting term used in cricket and baseball to refer to the area of the field of play further from the batsman or batter than the infield, and in association football to players outside the goal.  - At the end of each Major League Baseball season, the league leaders of various statistical categories are announced.

The pitcher is often considered the most important defensive player, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and closer.  - A right fielder, abbreviated RF, is the outfielder in baseball or softball who plays defense in right field. Right field is the area of the outfield to the right of a person standing at home plate and facing towards the pitcher's mound.
