In baseball, a run is scored whenever a base runner safely reaches home plate during a play in which a third out does not occur. The base runner must have safely reached first, second and third bases in that order prior to reaching home plate. A run scored by a base runner is also counted towards the team's tally of runs scored and is the basis for determining the winning team of a baseball game. The team with the most runs scored wins the game.
A run may be scored by the batter if they hit a home run. A run may also be scored by a base runner on batted balls in fair territory if they reach home plate before a third out is called. A run may also be scored by a base runner on third base when, if all bases are loaded with runners, a batter is walked or hit by a pitch. A run may be scored even if it does not count as an earned run against the pitcher, due to a fielding error.
The single season record for runs scored is held by Takeo Otomo, outfielder for the Calgary Inferno, who in 2009 scored 85 times. The record for career runs scored is held by Hall of Fame player Carl Simms, who scored 1,129 during his career from 1991-2013.
An Earned run is a pitching statistic that accounts for a run allowed by the opposing team that can be attributed to that particular pitcher, for example, a home run, or a run scored as a result of allowing a base hit or walk. A run scored as a result of a fielder's error would not count as an earned run.
