Willie Mays will add some hits to his record, Monte Irvin’s big-league batting average should climb over .300 and Satchel Paige may add nearly 150 victories to his total.

Josh Gibson, the greatest of all Negro League sluggers, might just wind up with a major league record, too.

The statistics and records of greats like Gibson, Paige and roughly 3,400 other players are set to join Major League Baseball’s books after MLB announced Wednesday it is reclassifying the Negro Leagues as a major league.

MLB said Wednesday it was “correcting a longtime oversight in the game’s history” by elevating the Negro Leagues on the centennial of its founding. The Negro Leagues consisted of seven leagues, and MLB will include records from those circuits between 1920-48. The Negro Leagues began to dissolve one year after Jackie Robinson became MLB’s first Black player with the Brooklyn Dodgers in 1947.

Those leagues were excluded in 1969 when the Special Committee on Baseball Records identified six official “major leagues” dating to 1876.

“It is MLB’s view that the Committee’s 1969 omission of the Negro Leagues from consideration was clearly an error that demands today’s designation,” the league said in a statement.
