<P> A more subtle, though more significant objection to the error, as sabermetricians have noted, is more conceptual . In order for a fielder to be charged with an error, he must have done something right by being in the correct place to be able to attempt the play . A poor fielder may "avoid" many errors simply by being unable to reach batted or thrown balls that a better fielder could successfully reach . Thus, it is possible that a poor fielder will have fewer errors than any fielder with higher expectancies . </P> <P> In recent times, official scorers have made some attempt to take a fielder's supposed "extraordinary" effort or positioning into account when judging whether the play should have been successful given ordinary effort . However, this still leaves statistics, such as fielding percentage, that are based on errors as a way to compare the defensive abilities of players . </P> <P> Errors also hold significance in calculating the earned run average (ERA) of a pitcher . Runs scored due to an error are unearned, and do not count toward a pitcher's ERA . </P> <P> In Major League Baseball, Herman Long holds the Major League records with 1096 errors in his career between 1889 and 1904 . Bill Dahlen, Deacon White and Germany Smith are the only other players to make 1,000 errors during their MLB careers . All of these players played at least one season before 1900 . The 20th century record is held by Rabbit Maranville with 711 errors . Among active players, Adrián Beltré leads with 275 errors over 2475 career games as of June 14, 2015 . </P>
